Thanks, we'll add that to the list. We have a few updates queued up for when we 
cut the next release, and one of them is a similar model:


Note that the EPFCLCD models seem to have some of the same issues as the PFCLCD 


There are enough Cyber Power quirks that they get their own category in our 
issue tracker :-)

I'm not sure there's much we can do about this one. The UPS publishes a dummy 
value (sometimes shows up as 16V, sometimes the same as the nominal voltage), 
but I have heard that even the CyberPower software doesn't have a way to report 
the battery voltage.

It should be possible to fix this one at some point:


We just got a contribution of some code to be able to patch the descriptor data 
coming back from the UPS, but we would also need to adapt that to be specific 
to the Cyber Power devices. Not sure if that will make it into the next 
release, though.

Your NAS firmware may take care of this, but you will want to make sure that 
your shutdown delay is greater than 60 seconds - the UPS only takes values in 
whole minutes, but NUT represents time in seconds (and rounds down,
