SCRIPT ENVIRONMENT for Heyu scripts
SCRIPT ENVIRONMENT for Xtend scripts
Heyu is a program for controlling an X-10 "CM11A" home control device.
See the heyu(1) man page for usage information.
This page contains information regarding the capabilities of Heyu
version 2 for launching scripts upon reception of specified X10 signals
or special conditions. The word 'script' as used here encompasses
not only shell scripts but also executable binaries and shell commands,
in fact, any valid command line.
(The auxilliary program Xtend by David Shaw which was required by
earlier versions of Heyu for this functionality is no longer needed or used.)
In order to launch scripts the Heyu state engine daemon must be running.
It is started manually by executing 'heyu engine', or can be configured
to start automatically with the 'heyu start' command by including the directive
"START_ENGINE AUTO" in the configuration file. If the Heyu configuration
file is changed, the daemon must be restarted by executing 'heyu restart' -
the existing daemon will re-read the configuration file and incorporate
Scripts to be launched are each defined in the Heyu configuration file with a
SCRIPT directive. This directive (more fully explained below) defines
the launch conditions under which a command line will be executed and the command
line itself. For each event, i.e., X10 signal or special condition, encountered
by Heyu the list of SCRIPT launch conditions are tested in the order the SCRIPT
directives appear in the configuration file. The command line is executed for
the first set of corresponding launch conditions which are satisfied. Any given
event can normally launch no more than a single SCRIPT command line, but see
section "SCAN MODE" below to override this restriction.
There are eight types of scripts which can be launched by Heyu:
Normal scripts are launched by an X10 function signal, e.g., 'on', 'off',
etc., which can be either sent or received.
Address scripts are similar to normal scripts but require only an
X10 address signal.
Powerfail scripts are launched when the restoration of AC power following
an interruption is reported to the computer by the CM11A.
RFFlood scripts are launched when an unbroken stream of RF signals
are received by the auxiliary input daemon heyu_aux.
RFJamming scripts are launched by an RF Jamming signal
reported by older firmware versions of RFXCOM receivers.
Timeout scripts are launched at expiration of a countdown time specified
by the user with a 'heyu settimer n hh:mm:ss' command or by a script with the
'@settimer n hh:mm:ss' precommand.
Exec scripts are launched only from the command line with the
'heyu launch <scriptname>' command, not by any signal or hardware condition.
Sensorfail scripts are launched when a sensor with a heartbeat
(i.e., which periodically reports its current state), fails to report in the
specified time, however they are now deprecated.
As of heyu-2.9, when an inactive sensor is detected Heyu generates the pseudo-signal
"Inactive" which appears to have been transmitted by the sensor. The function
"inactive" can be used in the launch conditions for a Normal script the same
as any other function, however one difference is that the "changed" launched condition
refers only to the transition from Active to Inactive rather than a change in
the data value as for real signals. The directive "HIDE_UNCHANGED_INACTIVE YES|NO"
(default NO) determines whether the unchanged pseudo-signal is displayed in the
monitor and logfile.
Sensorfail scripts are ignored under this new system.
The config directive "INACTIVE_HANDLING OLD" can be used to revert to the
The Heyu state engine daemon (heyu_engine) interprets X10 signals, both those
received over the AC power line via the CM11A interface, those sent to the
interface from the Heyu command line, and those RF signals transceived or
forwarded from the heyu_aux daemon. It keeps a record of the effect of these
signals upon each X10 module identified in an ALIAS directive in the
configuration file (or the default module). See the x10config(5) man
page for details about this.
Heyu classifies each X10 signal by its source, which will be one of the
sndc - Sent from the Heyu command line.
snds - Sent by Heyu executed from a normal or address script. (*)
sndp - Sent by Heyu executed from a power-fail script. (*)
sndm - Sent by an uploaded macro when initiated by a Timer.
sndt - Sent by an uploaded macro when initiated by a Trigger.
snda - RF transceived to power line code by the heyu_aux daemon.
rcva - RF signals forwarded from the heyu_aux daemon.
rcvi - Received over the AC power line.
rcvt - A Trigger signal which initiated an uploaded macro.
(*) When that script is launched by the Heyu state engine daemon.
The launch conditions for a script requires that the source or sources
to be allowed to launch the script be specified if other than the
default 'rcvi'. Using the source keyword 'anysrc' is equivalent to
specifying all the above mentioned sources except 'snds'. If you
are new to using Heyu scripts, including 'anysrc' in the launch
conditions for your scripts is probably a good idea until you gain
Note that a CM11A does NOT report the individual addresses and
functions when a macro is executed, only the fact that a macro at
EEPROM address XXX has been executed. Heyu determines the individual
addresses and functions from a copy of the EEPROM memory image it
stores in file 'x10image' when a schedule is uploaded to the CM11A.
Neither does the CM11A report the actual X10 signal which triggers
a macro, at least not reliably. Again, Heyu determines this from the
stored memory image file. (The CM11A firmware allows Heyu to distinguish
up to six different triggers for the _same_ macro.)
Each X10 standard module in the system can be in the major states
On, Dimmed, and Off. They are not mutually exclusive - a
module that is in the Dimmed state is also considered to be in the
There are additional major states for X10 security sensors and remotes,
e.g., Alert, Clear, Active, Inactive.
In addition, there are minor states: Addressed, Changed,
A module is considered to be in the ModuleChanged state when the
last X10 signal matching its housecode and unit caused a change in its
A module is considered to be in the Changed state when:
It's in the ModuleChanged state -OR-
If the X10 signal matching its housecode and unit is the first
valid signal encountered since start or restart -OR-
For sensors with a heartbeat, if the sensor first becomes Inactive
or returns to Active status.
(A signal is considered "valid" if it is supported by the module type in
Addressing is a feature built into module firmware and emulated
in the Heyu state engine.
A standard X10 module becomes Addressed when it receives an
X10 address code matching its own housecode|unit address.
It becomes unaddressed when it receives an X10 address code not
matching its own address after having received _any_ X10 function
code on the same housecode -or- when it receives the 'alloff'
(all_units_off) function on that housecode.
The X-10 company has not been consistant with their designs and some,
but not all, dimmer modules which support the 'lightsoff' (all_lights_off)
command will become unaddressed after receiving that command, and
some dimmer modules will become unaddressed after receiving the 'lightson'
(all_lights_on) command. Similarly there are some modules, usually
X10 camera power supplies, which are not unaddressed by the 'alloff'
SwitchLinc and other modules which support the 'preset' function
automatically unaddress themselves insofar as a subsequent 'preset'
function is concerned immediately after receiving any X10 function code.
The state tables maintained by the Heyu state engine daemon include
common flags which can be set or cleared by Heyu commands. The state
of one or more flags, "flagNN" or "notflagNN", can be included as part
of the conditions determining whether a script is to be executed.
Heyu counters set a "counter-zero" ("czflagNN") flag when the corresponding
counter NN value is zero. Heyu user-configurable countdown timers set
a "timer-zero" ("tzflagNN") flag when the corresponding timer NN is zero.
Heyu's security commands set flags,
e.g., 'armed', 'disarmed', etc., which can also be tested as part
of the launch conditions. If the LONGITUDE and LATITUDE directives are
included in the user's configuration file, the flags 'night' and 'dark'
and their negations 'notnight' and 'notdark' can also be tested in
the launch conditions.
The user can choose to run in a mode compatible with the heyuhelper
feature of Heyu 1.xx, a mode compatible with (most) Xtend scripts, or
with the full features of Heyu scripting. For heyuhelper, put
the directive SCRIPT_MODE HEYUHELPER in your configuration file,
otherwise specify (or take the default) SCRIPT_MODE SCRIPTS.
When SCRIPT_MODE HEYUHELPER is specified, all the other script-oriented
directives described below except SCRIPT_SHELL and SCRIPT_CTRL are ignored.
If an executable script named 'heyuhelper' exists on the user's path,
it is launched every time Heyu receives an X10 function over the AC power
line via the CM11A interface. One difference from Heyu 1.xx however is
that the heyuhelper script is NOT launched when an uploaded macro
For those anxious to get started without having to understand all of
Heyu's extended scripting features, just take the default for
SCRIPT_MODE, add one or more simple SCRIPT directives like the
following to your configuration file, and run 'heyu engine' to
start the Heyu state engine (or 'heyu restart' if its already
running). The simple SCRIPT format for (normal) scripts is:
SCRIPT <Housecode|unit> <function> anysrc :: <command line>
The Housecode|Unit, function, and keyword "anysrc" taken together describe
for Heyu the launch condition, i.e., the condition under which
the command line is to be executed.
The Housecode|Unit can be an ALIAS defined in the configuration file.
The keyword "anysrc" allows Heyu to satisfy the launch condition regardless
of the source of the X10 signal, e.g., whether received over the power
line or sent from the command line. Later you may wish to restrict the
source(s) of the signal to specific ones from the list of sources above.
SCRIPT porch_light on anysrc :: echo "Porch light has been turned on" | mail
The above sends an email to you whenever the X10 'on' signal for the
housecode|unit aliased to 'porch_light' is received over the power line
or sent from the command line.
SCRIPT C1 off anysrc :: play ssb.wav; heyu turn tv_set off
When remote X10 signal 'C1 off' is received, play the Star Spangled
Banner .wav file, then turn off the TV set. Users outside the USA
can substitute a .wav file for "O Canada", "God Save the Queen", or
whatever TV station signoff music is usual in their country. :-)
Note: The '::' (two colons) is a mandatory separator between the
launch condition (e.g. 'C1 off') and the command line.
Unless redirected elsewhere, any text output from a launched script
will be written to the log file.
Address scripts are similar to normal scripts but the keyword 'address'
is substituted in place of any and all function names. Example:
SCRIPT A1 address anysrc :: mysound.sh volumeup
SCRIPT A2 address anysrc :: mysound.sh volumedown
For powerfail scripts the simple SCRIPT format is:
SCRIPT -powerfail :: <command line>
SCRIPT -powerfail :: heyu on night_lights
Define for Heyu a script to be launched and the conditions for
launching it with a SCRIPT directive in your configuration file.
Any number of SCRIPT directives may appear in the configuration
The format is:
SCRIPT [-l label] <launch conditions> :: [options] <command line>
<launch conditions> tell Heyu under what conditions the script is
to be launched. See the section LAUNCH CONDITIONS below for full
details. <launch conditions> may alternatively (or additionally)
be specified with a LAUNCHER directive in the configuration file.
Launch conditions are tested in the order they appear in the
configuration file. The command line will be executed for the
first (and only the first) set of launch conditions which are satisfied,
i.e., only one command line can be executed per X10 signal or special
The script label is optional so long as all the launch conditions
are specified in the SCRIPT directive. If omitted, Heyu will create a
label for display purposes of the form 'Script_NN', where NN is the
line number of the SCRIPT directive in the configuration file.
If script labels are provided, they must be unique for each SCRIPT
A script label is mandatory when any launch conditions are separately
specified with a LAUNCHER directive - Heyu needs it to match up
the launcher with its corresponding script. But most users probably
won't bother with the LAUNCHER directives.
The symbol '::' (two colons) is mandatory, to tell Heyu when
the list of launch conditions ends and the command line begins.
When a script is launched, Heyu provides additional environment
variables containing information from Heyu's record of the state
of each module, plus a few other variables to simplify writing
the script. The script options allow some variation in the
type and format of these environment variables.
Script options are:
-xtend (or simply -x) - Provide an environment compatible with Xtend scripts.
-rawlevel (or simply -r) - Include native dimlevel of modules instead of
percentage of full On level in the Heyu environment, i.e., for standard
modules 0-210; for preset modules 1-32; for extended code modules 0-62; for VDATA
modules 0-255. This option is incompatible with the -xtend option.
-noenv (or simply -n) - Provide no environment variables beyond those
which already exist in the user's environment.
-quiet (or simply -q) - Heyu will normally display the script label
along with the full command line in the log file when a script is launched.
This option directs Heyu to display only the script label - useful if you
have a very long command line and dont want to clutter your log file.
-qquiet (or simply -qq) - This option directs Heyu suppress
display of even the script label in the log file when a script is launched.
It may be useful when you have a bunch of interrelated SCRIPT directives
and having the launching of all of them displayed in the log file is more
confusing than instructive. However please use this only after you have
confirmed that your scripts are working correctly and reliably.
Script options must be placed between the '::' separator and the
start of the command line.
SCRIPT D1 off :: -x myxtend.sh
See the section SCRIPT ENVIRONMENT below for a description of these
LAUNCH CONDITIONS FOR NORMAL SCRIPTS
The launch conditions tell Heyu under what conditions a script is
to be launched. Each time an X10 function is sent or received (or
a power-fail signal is received - more about this in the next section),
Heyu will test to see which (if any) of the conditions are satisfied.
The testing is performed in the order in which the conditions are
specified in the configuration file, and stops once the conditions
are matched and a script is launched.
For normal scripts, each set of launch conditions specifies the
affected housecode|units, the function or functions, optional
function mode keywords, the allowed source(s) of the functions,
and optional flag conditions.
HU functions [keywords] [sources] [flags]
The housecode|units string 'HU' must always come first and must always include
a units list even when a function like 'alloff' (all units off) is specified.
Using an asterisk ('*') in place of a units list, 'H*', will launch on any unit
1-16 but in the context of a launch condition will launch even when no units are
addressed, so can be used when it is desired to specify a launch when one of the
specified functions is received for that housecode regardless of unit addresses.
An alias may be used in place of a housecode|units string. Functions,
keywords, and sources may appear in any order after that.
Whether included within the SCRIPT directive or separately in LAUNCHER
directives, multiple launch conditions for the same script may be
continued on the same line by separating each group of conditions with
a semicolon (';'), i.e.,
HU functions [keywords] [sources] [flags]; HU functions [keywords] [sources] [flags]; ...
Functions which can be specified in a launch condition are any of the
native X10 functions: on, off, dim, bright, lightson, lightsoff,
alloff, preset, extended, hail, hail_ack, status, status_on,
status_off, data_xfer. Also functions allon, xpowerup, and vdata.
The general functions 'anyplc' or 'anyfunc' in a launch condition
will match any of the above.
RF signals received from X10 security remotes and sensors via the
heyu_aux daemon provide the additional functions disarm, arm, alert,
clear, panic, slightson, slightsoff, sdusk, and sdawn. The general functions
'anysec' or 'anyfunc' will match any of these.
RF signals from RFXSensor 1-Wire temperature, humidity, and barometric pressure
sensors which can be used in launch conditions are rfxtemp, rfxtemp2,
rfxrh, rfxbp, rfxlobat, rfxvad, rfxpot, and rfxvs. The general functions
'anyrfx' or 'anyfunc' will match any of these.
For more details see man page x10rfxsensors(5).
RF signals from RFXMeter power, water, gas, and pulse meters and counters
which can be used in launch conditions are: rfxpower, rfxwater,
rfxgas, rfxpulse, and rfxcount. The general functions
'anyrfx' or 'anyfunc' will match any of these.
For more details see man page x10rfxmeters(5).
RF signals from Oregon sensors which can be used in launch conditions are:
oretemp, orerh, orebp, and orewgt.
For more details see man page x10oregon(5).
RF signals from DigiMax 210 Thermostats which can be used in launch
conditions are: dmxtemp, dmxon, dmxoff, and dmxsetpoint.
For more information see man page x10digimax(5).
The 'allon' function is Heyu-defined
and in reality is just the 'on' signal when sent to
all 16 unit codes on a housecode. (Note: 'allon' as used in Heyu 1.xx
is the same as 'lightson', which is not the case here.)
The 'xpowerup' function is sent by X-10 2-way modules like the LM14A and
AM14A at power-up following an AC power interruption of at least a few seconds
Heyu also defines three 'generic' functions: gon, goff, and gdim.
The generic 'gon' encompasses any of: on, lightson, allon, preset level 32, or
extended preset level 62 or 63.
The generic 'goff' encompasses any of: off, lightsoff, alloff, preset level 1,
or extended preset level 0.
The generic 'gdim' encompasses any of: dim, bright, or any preset or extended preset
levels between the limits specified for 'gon' and 'goff'.
One or more functions can be specified in each launch condition. The logic
used when the HU contains more than one unit and/or there is more than one
function is illustrated in the following example:
SCRIPT A1,3 on off flag4 notflag7 :: myscript.sh
is equivalent to:
IF (A1 is addressed OR A3 is addressed) AND
(function On is received OR function Off is received) AND
flag4 is set AND flag7 is not set
If a macro is uploaded to the CM11A EEPROM memory and a powerline
trigger (e.g., "A1 on") is defined for it, the macro will
only be triggered when the powerline address signal immediately precedes
the powerline On function, with no intervening address or function
signals. Inclusion of the 'trigemu' keyword in the launch conditions
emulates this behavior.
Example: If the sequence "Addr A1, Addr A2, Addr A3, Func On A" is
received in that order, a script will be launched with the launch condition:
but not with the launch condition:
A2 on trigemu
because the Addr A3 signal intervened between the Addr A2 and the
Func On A signals.
Note: the 'trigemu' keyword is ignored for lightson, lightsoff,
alloff, and extended functions in the launch conditions.
In the default 'signal' mode, whether or not a script is launched
depends only on reception of the function at the housecode|unit as
specified in the launch condition and is independant of the module
at that address.
Inserting the keyword 'module' in the launch conditions results in
X10 signals being 'filtered' by the attributes of the modules before
the launch conditions are tested. For example, a script otherwise
programmed to be launched when the 'dim' signal is received would
not be launched if the module at the particular housecode|unit happened
to be an appliance module (as defined in the ALIAS directive).
Inserting the keyword 'changed' in the launch conditions inhibits
launching a script unless the function causes a change in the major
state of the module, i.e., if it's in the Changed state. For example,
the launch condition 'A1 off changed' will not launch the script
if the module at A1 is already in the Off state when the 'off' function
In the case of RF signals received from the auxiliary input daemon heyu_aux
(source RCVA), any difference in the data from the previous transmission
at the same housecode|unit address is considered a change. (The difference
in the data for it to be considered changed may be configured for Oregon
The keyword 'changed' automatically implies the filtering otherwise performed
when the keyword 'module' is specified and doesn't require separately
See section "SCAN MODE" below for the usage of these keywords.
By default, a script is launched only when the X10 function is received
over the AC power line (rcvi) by the CM11A interface. This can be extended
to other sources by including one or more source keywords in the launch
conditions. For example, 'A1 on sndc' would launch the script if
the function is either received over the power line (per the default rcvi)
or sent from the Heyu command line.
The source keyword 'anysrc' can be used to represent the sources
sndc, sndm, sndt, sndp, snda, rcvi, rcvt, rcva. It excludes the source 'snds'.
The source 'snds' can be separately specified if
you really have to use it, but ONLY when you have verified that its
use won't result in a script loop. A script loop WOULD result
in the following simple (and obvious) case:
SCRIPT A1 on rcvi snds :: heyu turn A1 on
however the possibility of a script loop may not be quite so obvious when you
have multiple and/or more complex SCRIPT directives.
Note that the default source or sources can be changed with the
LAUNCHER_SOURCE directive in the configuration file.
One can disallow default sources by prefixing the source with 'no',
e.g., 'norcvi', 'nosndm'. The keyword 'nosrc' has a special use - it has
the function of cancelling out all of the default sources. It must
always be accompanied by one or more actual source keywords if a script is
to be launched.
Warning: Functions with sources 'sndm' or 'sndt' are processed by Heyu
at the time it receives the signal from the CM11A that a macro has been
executed, which may be some time - seconds or even minutes depending on
the length of the macro - before the functions are actually transmitted
by the CM11A. Thus the state of the modules as recorded by Heyu will
be incorrect before the functions are actually transmitted. In addition,
the CM11A will not accept further commands while it's in the process
of transmitting the macro commands, so an attempt to send another command
may time out. To avoid these problems, the 'heyu wait' command can be used
to defer execution of a launched script until all macro commands have been
SCRIPT A1 on sndm :: heyu wait; (($X10_B2 & $isOn)) && heyu on C3
Flags which may be tested as part of the launch conditions are: state flags
which reflect the corresponding state of a module (see heading STATE FLAGS
below); common software flags flag1...flagNN set or cleared by Heyu state
commands; the counter-zero flags czflag1...czflagNN; the timer-zero flags
the global security flags disarmed, armed, notarmed, armpending, home, and away;
the flags night, dark, and their negations notnight and notdark; plus the
"local flag" security switch or low battery condition swhome, swaway, swmin,
swmax, and lobat transmitted by security remotes and sensors. (When
used by themselves, home or away imply armed.) RFXMeter sensors set
a testable 'rollover' local flag at the first signal after the counter
rolls over from its maximum value (0xFFFFFF) to zero. A local 'rollover'
flag is also set for other sensors which store and transmit cumulative
data, e.g., Oregon rain sensors.
The common flag "true-if-set" keywords are flag1, flag2, ... , flagNN. The
flag "true-if-clear" ("true-if-reset") terms are notflag1, notflag2, ... ,
notflagNN. Similar "true-if-clear" keywords are recognized for counter-zero
and timer-zero flags, e.g., notczflag1, nottzflag10;
Inclusion of one or more of the flag keywords in the launch condition
means that each and every flag state must be TRUE in order for the
script to be executed. In other words, the flag state is AND'd with
all the other launch conditions.
SCRIPT B1 on rcvi flag4 flag6 notflag8 :: my_command
In the above, my_command will be executed when the B1 On signal is received
only if flags 4 and 6 are set and flag 8 is not set (clear).
SCRIPT back_door alert armed rcva :: heyu on siren
In the above, the module controlling a siren is turned on when the
back door is opened and the door/window security sensor on that door
transmits the alert signal while the system is armed.
SCRIPT motion_sensor on night :: heyu on porch_light
The above will turn on the porch_light only if the On signal
from the motion_sensor is received between Dusk and Dawn.
SCRIPT motion_sendsor on dark :: heyu on porch_light
The above is similar to the previous one, but the condition
is that the motion_sensor signal is received between
Dusk+Offset and Dawn-Offset, where Offset is defined by the
config directive ISDARK_OFFSET.
State flags are global and can be used in the launch conditions for any
script. They are TRUE when the corresponding state or flag state of a Hu
address is TRUE. Their use can simplify Heyu SCRIPT directives by making
it unnecessary to use shell logic to check the state of a module.
Up to 32 state flags may be used in a launch condition and each must be
TRUE for the script to be launched.
The format for a state flag consists of the state and Hu address separated
by a colon (':') with no embedded spaces, e.g., "on:B7" or "on:Porch_Light".
Like other flags, state flags are not case sensitive _except_ for an
alias label (like "Porch_Light") if used, since alias labels are always
case sensitive. If an alias label is used, it must be for a single unit alias.
The list of states which can be included in a state flag follows, but run
'heyu stateflaglist' to make sure you have the current list. In the following,
Hu is the Housecode|single_unit address or Alias label.
Prefixing a flag with "not" is the negation for all state flags.
on:Hu Hu is in the On state
off:Hu Same as noton:Hu
dim:Hu Hu is in the Dimmmed state
alert:Hu An Alert signal has put Hu into the alert state.
clear:Hu A Clear signal has put Hu into the clear state.
auxalert:Hu An AuxAlert signal has put Hu into the auxalert state.
auxclear:Hu An AuxClear signal has put Hu into the auxclear state.
sdusk:Hu An sDusk signal has put Hu into the sdusk state. (GB10, DM10)
sdawn:Hu An sDawn signal has put Hu into the sdawn state. (DM10)
valid:Hu A supported signal has been received since start.
active:Hu A valid signal has been received before INACTIVE_TIMEOUT.
inactive:Hu No valid signal has been received before INACTIVE_TIMEOUT.
addr:Hu The X10 module at Hu is in the addressed state.
tamper:Hu The tamper flag has been raised for sensor Hu.
chg:Hu The last signal on H resulted in a change of state for Hu.
lobat:Hu The low battery flag has been raised for sensor Hu.
rollover:Hu The rollover flag is raised for sensor Hu.
swmin:Hu The swMin flag has been raised for sensor Hu.
swmax:Hu The swMax flag has been raised for sensor Hu.
tmin:Hu The Tmin flag has been raised for sensor Hu.
tmax:Hu The Tmax flag has been raised for sensor Hu.
rhmin:Hu The RHmin flag has been raised for sensor Hu.
rhmax:Hu The RHmax flag has been raised for sensor Hu.
bpmin:Hu The BPmin flag has been raised for sensor Hu.
bpmax:Hu The BPmax flag has been raised for sensor Hu.
main:Hu The Main flag has been raised for sensor Hu.
aux:Hu The Aux flag has been raised for sensor Hu.
heat:Hu The DigiMax Heat flag has been raised.
set:Hu The DigiMax Setpoint Temperature Set flag has been raised.
init:Hu The DigiMax Initialazation Init flag has been raised.
Please note that for sensor signals in particular, the flag negation
does not necessarily imply an opposite state, e.g., until a valid
signal is received, both alert:Hu and clear:Hu may be FALSE, so that
notalert:Hu does not imply clear:Hu.
Similarly, after a start and until the first valid signal is
received or until an initial INACTIVE_TIMEOUT interval, both active:Hu and
inactive:Hu will be FALSE.
When a signal is received by the heyu_engine daemon, Heyu by default
scans the list of SCRIPT launch conditions and executes the command
line for the first one where its launch conditions are satisfied.
As there are occasions when it would be convenient to have more than
one SCRIPT command line be executed upon receipt of a signal, this
default behavior can be modified with a combination of the configuration
directive LAUNCHER_SCANMODE and launch condition keywords 'continue'
The config directive LAUNCHER_SCANMODE can take the parameters BREAK
or CONTINUE, with the default being BREAK. The parameter BREAK provides
the default behavior described above. With parameter CONTINUE, Heyu
will execute the command line for all SCRIPTs where the launch conditions
The scan mode specified by LAUNCHER_SCANMODE can be overridden for
individual SCRIPTs by including the keyword 'continue' or 'break'
in the launch conditions. Following are some simple (trivial) examples.
SCRIPT -l DimLights A1 on rcvi continue :: heyu turn B1,2,3 dimb 10
SCRIPT -l TurnOnTV A1 on rcvi :: heyu turn tv_set on
SCRIPT -l TurnOffTV A1 on rcvi :: heyu turn tv_set off
In the above example, receipt of signal "A1 On" results in the command lines
for both DimLights and TurnOnTV being executed. TurnOffTV is not
executed because the scan mode reverts to BREAK when TurnOnTV is executed.
SCRIPT -l DimLights A1 on rcvi :: heyu turn B1,2,3 dimb 10
SCRIPT -l TurnOnTV A1 on rcvi break :: heyu turn tv_set on
SCRIPT -l TurnOffTV A1 on rcvi :: heyu turn tv_set off
The above works the same as the first example - the 'break' keyword
in TurnOnTV tells Heyu to stop scanning once its launch conditions are
Tip: In most cases users will find it more convenient and less confusing
to keep the default "LAUNCHER_SCANMODE BREAK" and use the 'continue'
keyword where required.
It's ESSENTIAL to understand what happens in Heyu when using the
continue and break features.
When a signal is received by heyu_engine, Heyu starts scanning the list
of launch conditions and tags those where the conditions are satisfied.
It stops scanning when a launch condition is satisfied and the scan mode
is BREAK. Heyu then goes back and executes in order the command lines for
all SCRIPTs which were tagged in the first pass.
Several things to keep in mind:
When more than one script is executed, the launch condition for subsequent
scripts may no longer be true if conditions are modified by a preceding
script, but the script is launched nevertherless.
SCRIPT -l ResetFlag A1 on rcvi flag1 continue :: @clrflag 1
SCRIPT -l DoSomething A1 on rcvi flag1 :: something.sh
In the example above, both scripts will be executed if Flag 1 is set
when signal A1 On is received. But when script DoSomething is executed, condition
flag1 will no longer be TRUE since the flag will have been cleared by execution
of the previous script ResetFlag command line. This may be important if the shell
script "something.sh" relies on the value of environment variable $X10_Flag1 or
calls 'heyu flagstate 1' to direct its operation.
Secondly, when multiple shell commands or shell scripts are executed, the
order of actual command execution is determined in part by the operating system,
with each script getting its multitasking time slices (typically 10 milliseconds).
(This does not apply to the internal engine precommands like @clrflag which are
executed within heyu_engine before shelling out the remainder of the command line.)
LAUNCH CONDITIONS FOR ADDRESS SCRIPTS
Launch conditions are identical to those for normal scripts except the
keyword 'address' is used in place of any and all functions. Neither
functions nor the keywords 'changed', 'signal' or 'module' may
be specified for address scripts. (Likewise, the keyword 'address'
may not appear in the launch conditions for normal acripts.) The launch
conditions may include sources and flags as for normal scripts.
Note that the launch conditions for address scripts are evaluated each
time an address signal is encountered and those for normal scripts
each time a function signal is encountered, so it's possible to have
multiple script launchings for what might appear to be a single X10
command but which in reality is two separate events.
LAUNCH CONDITIONS FOR POWERFAIL SCRIPTS
For powerfail scripts, the launch conditions always start with the
special keyword '-powerfail' (note the '-' prefix) and may optionally
be followed with flag conditions. (Module addresses, functions, and sources
are not applicable for powerfail scripts.)
As with normal scripts, each of the specified flag conditions must be TRUE for
the script to be launched, and the same flag1, flag2, ..., flagNN and
notflag1, notflag2, ..., notflagNN keywords are valid. Security flags
(disarmed, armed, armpending, home, away) may also be tested, however they
may not be valid if the computer has been powered down during the power
In addition there are two special flags, 'boot' and 'notboot' which
are valid only for powerfail launchers. The boot flag is set by the
Heyu relay daemon at the time it is first started and cleared a few
If the boot flag is included in the launch condition,
then the script will be launched only if the powerfail signal is received
immediately following the startup of the Heyu relay
daemon, i.e., if the CM11A is polling for a clock update at the time
Heyu is first started.
Conversely, if the notboot flag is included in the launch condition,
the script will be launched only if the powerfail signal is received
after the initial refractory period of a few seconds.
If neither the boot nor the notboot flag is included, then the script
will be launched regardless of the time the powerfail signal is received.
Note: A powerfail script can be launched at startup ONLY if Heyu is
started with the 'heyu engine' or 'heyu start' commands, else the
state engine daemon won't be running in time to catch the powerfail
signal at startup.
LAUNCH CONDITIONS FOR RFFLOOD SCRIPTS
An RFflood signal is issued with the "started" flag when an RF flood
is first detected, then again at increasing longer intervals while the
flood continues. Another RFflood signal is issued with the "ended"
flag when the flood ceases. Either of these two flags can be tested
in the launch conditions along with any of the other flags.
Housecode|unit addresses, functions, and sources are not applicable
for RFFLOOD script launch conditions.
LAUNCH CONDITIONS FOR RFJAMMING SCRIPTS
An RFJamming signal is issued with either the "started" or "ended"
flag as reported by an (older) RFXCOM receiver, and with the "main"
or "aux" flag depending on whether the signal originated with the
master or slave RFXCOM receiver. All of these flags can be tested
in the launch conditions along with any of the other flags.
-rfjamming started aux
Housecode|unit addresses, functions, and sources are not applicable
for RFJAMMING script launch conditions.
LAUNCH CONDITIONS FOR SENSORFAIL SCRIPTS
Sensorfail scripts are deprecated and ignored in favor of the Inactive
pseudo-signal unless config directive "INACTIVE_HANDLING OLD" is used.
If Heyu has not received any signal from a security sensor with a
heartbeat, either a normal alert or its periodic "alive" signal, in
the interval specified by the INACTIVE_TIMEOUT directive, it can
launch a '-sensorfail' script. Any of the global flags may be included
in the launch conditions.
LAUNCH CONDITIONS FOR TIMEOUT SCRIPTS
Heyu can launch a script when a countdown timer set by the user
reaches zero. The particular timer must be specified. Any of the
global flags may also be included.
-timeout timer2 flag3
LAUNCH CONDITIONS FOR EXEC SCRIPTS
Exec script launch conditions may include only global flags, i.e.,
State flags, e.g., on:B7, dim:A4
flag1 ... flagNN, notflag1 ... notflagNN
czflag1 ... czflagNN, notczflag1 ... notczflagNN
night, notnight, dark, notdark.
disarmed, armed, notarmed, armpending, home, away, tamper.
-exec armed away night flag1
If there are no flags in the launch conditions the "::" separator is
still required, e.g.,
-exec :: <command_line>
Launchers are an alternative way of specifying the launch conditions
for a script. They can be useful when you have multiple or very complex
sets of launch conditions, otherwise most users will probably find it
more convenient (and less confusing) to include all the launch conditions
in the SCRIPT directive.
The format for a launcher directive in the configuration file is:
LAUNCHER <script_label> HU functions [keywords] [sources] [flags]; HU functions [keywords] [sources] [flags]; ...
where the mandatory script_label (no -l switch is used here) must match
the label in the SCRIPT directive to which it applies.
SCRIPT COMMAND LINE
The command line can be any valid command line for the OS and shell,
including shell commands and logic, shell scripts, binary executables,
and multiple strings of these delimited by semicolons.
In addition, there are internal engine precommands which can be used
at the beginning of the command line to set flags and countdown
timers. These are processed by the engine before the remainder of the
line, if any, is actually launched as a child process. Their use
guarantees that their functions are carried out in the order the
scripts are launched, as opposed to the order in which child
processes might actually execute them as direct commands when there are
multiple child processes launched in rapid succession.
These precommands are: @arm, @disarm, @setflag, @clrflag, @settimer,
@setrtimer, @clrtimers, @clrspend, @vdata, @vmdata, @setcount, @inccount,
@deccount, @decskpz, @decskpgz, @decskpgziz, and @null. They take the
same parameters and operate the same as the corresponding direct commands
without the '@' prefix. (The @null does nothing and can be used as a
placeholder to serve as an empty command line, which would otherwise
generate an error message.) They are not used as parameters to Heyu but
as stand-alone commands, and must appear in the command line before any
SCRIPT A1 off :: @settimer 7 0
SCRIPT A1 on :: @setflag 3; @settimer 7 5; heyu on A2
The @decskpz, @decskpgz, @decskpnziz (decrement/skip) precommands and
@null precommand don't have corresponding direct commands. In addition
to decrementing the counter, a @decskpxxx also terminates further
execution of the command line ("skips") when the decrement and skip conditions
The '@decskpz N' decrements counter N and skips if the result is zero.
The '@decskpgz N' decrements counter N and skips if the result is greater
The '@decskpnziz N' decrements counter N and skips if the result is
non-zero or if the counter is initially zero. It emulates the similar
command in computer languages where the counter is a variable which can
be considered to have negative values. Insofar as Heyu is concerned, it
will skip when the result is greater than zero, not skip when the counter
is first decremented to zero, but then skip on further _attempted_
decrements since a zero Heyu counter cannot be decremented further. In
other words its function is to "decrement and skip on non-zero then run
only the first time the counter goes to zero".
If counter 7 has previously been set to the value 3 and we have:
SCRIPT A1 on :: @decskpz 7; heyu on A2; ...
then the remainder of the command line following the @decskpz precommand
will be executed on the first and second "A1 on" signals but ignored for
subsequent "A1 on" signals. Conversely, if we start with the same
counter setting and have:
SCRIPT A1 on :: @decskpnziz 7; heyu on A2; ...
then the remainder of the command line will be ignored until the counter
reaches zero, when it will be executed. The remainder of the
command line will also be ignored if the value of the counter is initially
zero since it can't be decremented further.
SCRIPT ENVIRONMENT for Heyu scripts
When the -xtend option is NOT specified, Heyu provides a number of
environment variables which can be used by scripts. Here is a
summary - see below for descriptions and examples:
X10_A1 ... X10_P16
x10_<alias> ... (Note lower case prefix 'x10_')
whatLevel, isAppl, isSpend, isOff, isOn, isAddr, isChg, isDim, isAlert, isClear, isAuxAlert,
isAuxClear, isValid, isActive, isInactive, isSdusk, isSdawn
isLoBat, isRollover, isSwMin, isSwMax, isMain, isAux, isTamper, isTmin, isTmax, isRHmin, isRHmax,
isBPmin, isBPmax, isSet, isHeat, isInit.
X10_Housecode, X10_Unit, X10_LastUnit, X10_Function, X10_function, X10_Source, X10_UnitAlias, X10_Linmap
X10_BrightVal, X10_DimVal, X10_RawVal
X10_Flag1, X10_Flag2, ... , X10_FlagNN
X10_Timer1, X10_Timer2, ..., X10_TimerNN
X10_Counter1, X10_Counter2, ..., X10_CounterNN
X10_Year, X10_Month, X10_MonthName,
X10_Day, X10_Hour, X10_Minute, X10_Second, X10_WeekDay,
X10_WeekDayName, X10_isDST, X10_DateString, X10_GMT
X10_DawnTime, X10_DuskTime, X10_SysTime
X10_Disarmed, X10_Armed, X10_ArmPending, X10_Home, X10_Away
X10_swMin, X10_swMax, X10_swHome, X10_swAway, X10_LoBat
The environment variable X10CONFIG contains the full pathname of
the configuration file in effect for the Heyu state engine.
Unless overridden, instances of Heyu executed by a script will
therefore automatically use the same configuration file.
For each housecode|unit 'Hu', the state variable 'X10_Hu=bitmap'
where the bit values in 'bitmap' are defined by mask variables
of the form 'isXXX'.
(Run heyu masklist to insure having a current list.)
'whatLevel' (Bits 0 through 7 represent the module dim level, or for
security devices, the security data byte).
'isAppl' Unit has no Dim/Bright attribute.
'isSpend' Status pending bit.
'isOff' Unit is not in the On state
'isAddr' Unit is Addressed
'isChg' Unit is Changed
'isDim' Unit is Dimmed
'isValid' A supported signal has been sent/received.
'isClear' The sensor is in the Clear state.
'isAlert' The sensor is in the Alert state.
'isAuxClear' the sensor is in the AuxClear state.
'isAuxAlert' The sensor is in the AuxAlert state.
'isSdawn' The security sensor is in the sDawn state.
'isSdusk' The security sensor is in the sDusk state.
'isActive' A signal or heartbeat has been received within
the INACTIVE_TIMEOUT interval
'isInactive' No signal or heartbeat has been received within
the INACTIVE_TIMEOUT interval.
'isOn' Unit is in the On state.
The module dim level will be either the integer 0 through 100
representing the percentage of full brightness, or the native
module level (0-210, 1-32, 0-62, or 0-255) if the -rawlevel script
option is specified. (The dim level for an appliance module will
be either the lowest value if it's Off or the highest value
if it's On.)
Note that for states controlled by sensor signals, e.g., Alert/Clear,
the sensor will be in neither corresponding state following
start or restart until a Valid signal is received, or in the case
of Active/Inactive until the INACTIVE_TIMEOUT interval has elapsed.
For each single-unit ALIAS defined in the configuration file, the
state variable 'x10_<alias_label>=bitmap', e.g.,
where <bitmap> is as described above.
For X10 Security and other RF devices, the variables 'X10_Hu_vFlags'
and 'x10_<alias_label>_vFlags'. These are bitmaps with bits which
may also be tested with masks. Run heyu masklist for a complete
current list, but here are some commonly used ones:
'isLoBat' Low battery flag
'isRollover' Rollover flag.
'isSwMin' Door/Window sensor Min switch
'isSwMax' Door/Window sensor Max switch
'isMain' Main channel of two-channel sensor
'isAux' Aux channel of two-channel sensor
'isTamper' Tamper flag
'isTmin' Min temperature flag
'isTmax' Max temperature flag
'isRHmin' Min Relative Humidity flag
'isRHmax' Max Relative Humidity flag
'isBPmin' Min Barometric Pressure flag
'isBPmax' Max Barometric Pressure flag
'isSet' DigiMax Setpoint temperature is Set mode flag
'isHeat' DigiMax Heat mode flag
'isInit' Digimax Initialation Init flag
Note that the prefix for ALIASes is the lower case 'x10' to avoid
possible conflict with the other Heyu environment variables which
are prefixed with the upper case 'X10'. The configuration
directive ENV_ALIAS_PREFIX can be used to revert to the upper case
prefix for compatibility with existing scripts if absolutely
necessary but is deprecated.
Mask variables are used to test the state variables without
having to remember the bitmap values.
Example: In the bash shell, the construct
(($x10_porch_light & $isOn))
will return TRUE ( > 0 ) if the module aliased to porch_light
is in the On state, and
level=$(($x10_porch_light & $whatLevel))
will recover the brightness level of the module aliased to porch_light.
Note: The bash construct above is compact and convenient, but is not
defined by POSIX. Other shells will have to use the POSIX compatible
[ $(($x10_porch_light & $isOn)) -ne 0 ]
to test the state of the module.
The mask variables should always be used instead of the
numeric values for testing the state of a module. The numeric
values (for the Heyu environment) may change in a future release
of Heyu. (The bit representing 'On' is however guaranteed to
always have the highest numeric value, so that a test for 'On'
like the example in the Xtend documentation $X10_B4>=128 will
continue to work so long as the mask is used rather than the
numeric value, i.e., $X10_B4>=$isOn.)
Details of the function which launched the (normal) script:
where 'X10_Unit' is the last unit _in X10 order_ of the
addressed units which resulted in launching the script, while
'X10_LastUnit' is the last addressed unit for that housecode
(which may or may not have resulted in launching the script).
'X10_UnitAlias' is the label of the alias corresponding to
the address 'X10_Housecode' and 'X10_Unit'.
'X10_Linmap' is a bitmap of all the addressed units which resulted
in launching the script, with 1 = unit 1, 2 = unit 2, 4 = unit 3,
8 = unit 4, etc.
where signal_source is "rcvi", "rcva", "sndc", etc. (Without the quotes.)
where <func> is one of the following (as appears in the Heyu
monitor and/or logfile):
AllOff, LightsOn, On, Off, Dim, Bright, LightsOff,
Extended, Hail, HailAck, Preset,
DataXfer, StatusOn, StatusOff, StatusReq, AllOn,
xPowerUp, vData, vDataM, Panic, Arm, Disarm,
Alert, Clear, Test, sLightsOn, sLightsOff, secTamper,
rfxTemp, rfxTemp2, rfxRH, rfxBP, rfxVad, rfxPot, rfxVs,
rfxLoBat, rfxOther, rfxPulse, rfxPower, rfxWater, rfxGas,
rfxCount, dmxTemp, dmxOn, dmxOff, dmxSetpoint,
oreTemp, oreRH, oreBP, oreWgt
As above, but <func> is lower case and where applicable can
be used as a Heyu command, e.g., 'heyu $X10_function Hu'.
(Note that the leading "X10_" remains upper case.)
And only when <func> is 'Preset':
And only when <func> is 'Extended':
And only when <func> is 'Dim' or 'Bright':
'X10_RawVal' (2-210) (Unsigned for both Bright and Dim)
'X10_DimVal' (2-210) (+ for Dim, - for Bright)
'X10_BrightVal' (2-210) (+ for Bright, - for Dim)
And only when <func> is 'Arm':
'X10_swHome' Logical (0 or 1)
'X10_swAway' Logical (0 or 1))
And only when <func> is 'Arm' or 'Alert' or 'Clear':
'X10_swMin' Logical (0 or 1)
'X10_swMax' Logical (0 or 1)
And only for -timeout scripts:
'X10_Timer' (= timer number 1-NN which launched script, or "armtimer")
And only for -sensorfail scripts:
'X10_Sensor' (= Housecode|Unit of sensor)
For RF data from X10 security, entertainment, RFXSensor, RFXMeter,
Digimax, and Oregon transmitters:
'X10_Vdata' or 'X10_vData' (0-255)
Temperature data from RCS compatible thermostats and remote thermometers
as X10_H0_Temp and x10_<alias_label>_Temp.
For RF data from RFXSensor 1-wire temperature, humidity, and barometric
pressure sensors: X10_Hu_Temp, X10_Hu_Temp2, X10_Hu_RH, X10_Hu_BP, X10_Hu_Vs,
X10_Hu_Vad, X10_Hu_Vadi, and X10_Hu_Pot. Also the alias versions of these
variables, i.e., x10_<alias_label>_Temp, etc.
For RF data from RFXMeter Power, Water, Gas, and Pulse meters and counters:
X10_Hu_Power, X10_Hu_Water, X10_Hu_Gas, X10_Hu_Pulse, and X10_Hu_Count.
Also the alias versions of these variables, i.e., x10_<alias_label>_Power, etc.
The variable X10_rollover has the Boolian value 1 or 0 depending whether or
not the 'rollover' local flag was set in the meter or counter signal which
launched the script.
For RF data from Oregon Temp/RH/BP sensors: X10_Hu_oreTemp, X10_Hu_oreRH,
X10_Hu_oreBP. For BP sensors which transmit a weather forecast: X10_Hu_oreForecast.
Also the alias versions of these variables, i.e., x10_<alias_label>_oreTemp. etc.
For RF data from Electrisave and CM113 power monitors: X10_Hu_elsCurr and
X10_Hu_elsPwr, and the alias version of these variables.
For RF data from Owl CM119 power monitors: X10_Hu_owlPower, X10_Hu_owlEnergy,
and the alias version of these variables.
Note: None of the environment variables relating to a housecode|unit
and function which launches a script exist for Powerfail, Sensorfail, RFFlood,
RFJamming, or Timeout scripts.
The flag environment variables, X10_Flag1 ... X10_FlagNN have values
1 or 0 when the corresponding flags are respectively set or cleared.
The user coundown timer environment variables, X10_Timer1 ... X10_TimerNN,
have the remaining times in seconds before timeout.
Variable X10_ArmPendingTimer has the time in seconds before the ArmPending
state will become the Armed state.
The counter environment variables, X10_Counter1, ..., X10_CounterNN have
the values 0-64K in those counters.
The Calendar/Clock variables for today's date and time:
'X10_Year' (e.g., 2004), 'X10_Month' (1-12), 'X10_MonthName' (Jan, Feb, etc.),
'X10_Day' (1-31), 'X10_Hour' (0-23), 'X10_Minute' (0-59),
'X10_Second' (0-59), 'X10_WeekDay' (0-6), 'X10_WeekDayName' (Sun, Mon, etc.).
'X10_isDST' is a logical variable which is TRUE if Daylight Saving Time is
currently in effect.
'X10_DateString' is an ASCII string with the date and time formatted as
displayed with events in the Heyu monitor and log file.
The variables 'X10_DawnTime', 'X10_DuskTime', and 'X10_SysTime', which
have the values for today's Dawn and Dusk time and the current system time.
All are expressed as seconds after 0:00:00 Civil (wall-clock) Time, although
Dawn and Dusk are computed by Heyu only to the nearest minute.
(Dawn and Dusk are defined by default to be synonymous with sunrise and sunset,
although this definition may be changed with the configuration file
directive DAWNDUSK_DEF. Their calculation require that the LONGITUDE
and LATITUDE of the user's location be defined in the configuration file,
otherwise these variables will be undefined. They will also be undefined
when there is no actual Dawn or Dusk event, as in polar latitudes during
various seasons of the year.)
The logical variable 'X10_isNightTime' which is TRUE between the
times of Dusk and Dawn.
The logical variable 'X10_isDarkTime' which is TRUE between the
times of Dusk and Dawn offset by +/- the number of minutes defined by
the configuration directive ISDARK_OFFSET. The default is 30 minutes,
meaning this variable will be TRUE between Dusk + 30 minutes and
Dawn - 30 minutes.
SCRIPT motion_detector on :: ( (($X10_SysTime > $X10_DuskTime)) ||
(($X10_SysTime < $X10_DawnTime)) ) && heyu turn outside_lights on
will result in turning on the modules aliased to 'outside_lights'
when the motion detector module sends the 'on' function, but only
between Dusk and Dawn. Note: This must all be written on one line.
Somewhat simpler in this case however is the equivalent:
SCRIPT motion_detector on :: (($X10_isNightTime)) &&
heyu turn outside_lights on
The variables 'helper' and 'bighelper'. These have the same format
as the command line argument passed to the heyuhelper script when the
directive SCRIPT_MODE HEYUHELPER is chosen, e.g., a1Dim. They allow
an existing heyuhelper script to be run under SCRIPT_MODE SCRIPTS by
specifying the command line in the SCRIPT directive as
SCRIPT <launch condition> :: heyuhelper $helper
SCRIPT <launch condition> :: heyuhelper $bighelper
This difference is that 'bighelper' will supply the housecode|unit
for every affected unit as successive command line arguments, whereas 'helper'
will supply the housecode|unit only for the last affected unit, the
same as in the heyuhelper feature of Heyu 1.xx.
For bighelper, the affected unit arguments will appear in reverse
X10 unit order, i.e.,
10, 2, 8, 16, 12, 4, 6, 14, 9, 1, 7, 15, 11, 3, 5, 13
so the first script argument will be the same for either helper or
The environment variable 'X10_Expire' contains the number of
days (0-365) before expiration of an uploaded schedule, or a
negative number with the following meaning:
-1 SCHEDULE_EXPIRED (Schedule must be reloaded)
-2 NO_EXPIRATION (Schedule contains no timers)
-3 NO_RECORD_FILE (No schedule has been uploaded)
-4 BAD_RECORD_FILE (File x10record is corrupted.)
(These are the same numeric values which would be displayed upon
execution of 'heyu upload cronstatus'.)
SCRIPT ENVIRONMENT for Xtend scripts
Xtend (http://www.jabberwocky.com/software/xtend/) by David Shaw
is an auxilliary program for launching scripts based on
received X10 power line signals. Heyu now provides internally all the
same functionality (and more) and Xtend is no longer needed.
The additional functionality of Heyu requires changes in the
environment provided for the script which make it incompatible
with scripts written for Xtend. For compatibility with existing
Xtend scripts, the -xtend script option tells Heyu
to instead supply the more limited but Xtend-compatible environment,
The environment variable X10CONFIG contains the full pathname of
the configuration file in effect for the Heyu state engine.
Unless overridden, instances of Heyu executed by a script will
therefore automatically use the same configuration file.
The state variables 'X10_Hu=xtend_bitmap' for each housecode and
unit 'Hu', where the bits in xtend_bitmap now have these values (which
correspond with Xtend's):
32 Unit is addressed.
64 Unit is an appliance module i.e., has no Dim/Bright attributes.
128 Unit is On.
The three mask variables 'isAddr', 'isAppl', and 'isOn', with values
appropriate for Xtend.
