o beeper.enable, beeper.disable, beeper.toggle
o shutdown.return, shutdown.reboot, shutdown.stayoff
On many devices, these commands are unreliable, so before using them you must verify that these work as expected (see Shutdown Issues).
Vendor support is absent for this driver, so if you need some features that are currently not available, provide ample documentation on what the driver should sent to the UPS in order to make this work. If more information would be available on the binary protocol, it would probably be possible to make ondelay and offdelay configurable. So far, nobody has taken the time to investigate what we should tell the UPS to make this work, and CyberPower isnt willing to share this with us.
If the shutdown.return command on your UPS doesnt seem to work, chances are that your UPS is an older model. Try a couple of different settings for offdelay. If no value in the range 6..600 works, your UPS likely doesnt support this. In order to get the expected behaviour, it requires shutdown.stayoff (when on battery) and shutdown.reboot (when on mains). The driver will automatically fallback to these commands if shutdown.return fails, and tries to detect which one should be used when called with the -k option (or through upsdrvctl shutdown).
This isnt bullet-proof, however, and you should be prepared that the power will either not be shutdown or that it doesnt return when the power comes back. All models supported by the binary protocol and many supported through the text protocol are affected by this.
The CyberPower OP series dont offer direct voltage, charge, frequency and temperature readings. Instead, they will return a binary value that needs conversion to the actual value.
The exact conversion needed is unknown at the time of this writing, hence an estimation was made based om readings from actual devices. This may (probably will) be off, possibly a lot. Unless you can tell us the exact mapping between values from the UPS and actual readings, dont bother to complain. Weve done the best we can based on the limited information available. Remember, a UPS isnt a measuring instrument.
