NAME

       powerpanel - Driver for PowerPanel Plus compatible UPS equipment

NOTE

       This man page only documents the hardware-specific features of the powerpanel driver. For information
       about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

       This driver supports CyberPower BC1200, PR2200 and many other similar devices, both for the text and
       binary protocols. The driver will autodetect which protocol is used.

EXTRA ARGUMENTS

       This driver supports the following optional settings in ups.conf(5):

       protocol=[text,binary]
           Override the default autodetection of the protocol.

       manufacturer=value
           If you don’t like the autodetected value, you can override this by setting it here.

       model=value
           Like manufacturer above.

       serial=value
           Like manufacturer above.

       ondelay=value
           Time to wait before switching on the UPS (1 - 9999 minutes, 0=indefinite). Only available with the
           text protocol driver (see Support Status).

       offdelay=value
           Time to wait before shutting down the UPS (6 - 600 seconds). Values below 60 seconds will be
           truncated to 6 seconds intervals, values above 60 seconds to 60 seconds intervals. Only available
           with the text protocol driver (see Support Status).

VARIABLES

       Depending on the type of your UPS unit, some of the following variables may be changed with upsrw(8). If
       the driver can’t read a variable from the UPS, it will not be made available.

       input.transfer.high
           writable: high transfer voltage point in V

       input.transfer.low
           writable: low transfer voltage point in V

       battery.charge.low
           writable: remaining battery charge percentage for low battery warning

       output.voltage.nominal
           writable: nominal output voltage in V

       ups.start.battery
           writable: allow cold start from battery

COMMANDS

       Depending on the type of your UPS unit, some of the following commands may be available.

       •   test.battery.start.quick, test.battery.stop

       •   beeper.enable, beeper.disable, beeper.toggle

       •   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).

       •   shutdown.stop

SUPPORT STATUS

       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 isn’t willing to share this with us.

SHUTDOWN ISSUES

       If the shutdown.return command on your UPS doesn’t 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 doesn’t 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 isn’t bullet-proof, however, and you should be prepared that the power will either not be shutdown
       or that it doesn’t return when the power comes back. All models supported by the binary protocol and many
       supported through the text protocol are affected by this.

KNOWN PROBLEMS

       The CyberPower OP series don’t 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, don’t bother to complain. We’ve done the
       best we can based on the limited information available. Remember, a UPS isn’t a measuring instrument.
