powerpanel - Driver for PowerPanel Plus compatible UPS equipment
This man page only documents the hardware-specific features of the
powerpanel driver. For information about the core driver, see
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.
This driver supports the following optional settings in ups.conf(5):
Override the default autodetection of the protocol.
If you don't like the autodetected value, you can override this
by setting it here.
Like manufacturer above.
Like manufacturer above.
Time to wait before switching on the UPS (1 - 9999 minutes, 0
indefinite). Only available with the text protocol driver (see
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).
Depending on the type of your UPS unit, some of the following variables
may be changed. If the driver can't read a variable from the UPS, it
will not be made available.
writable: high transfer voltage point in V
writable: low transfer voltage point in V
writable: remaining battery charge percentage for low
writable: nominal output voltage in V
writable: allow cold start from battery
Depending on the type of your UPS unit, some of the following commands
may be available.
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
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.
If the shutdown.return command on your UPS doesn't seem to work,
chances are that your UPS is of 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
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.
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
