Nut upsuser - Oct 2020 - Can't get CyberPower UPS to work with Raspberry Pi 4

actual battery voltage.
Here's what I was thinking of:

https://github.com/networkupstools/nut-ddl/blob/8995562a0253e980d36f6bdddfe09c9f2c866657/Cyber_Power_Systems/Cyber_Power_Systems__CP1500PFCLCD__usbhid-ups__2.7.1__01.dev#L11-L13

"CyberPower states that battery voltage is not supported in this model of
UPS. [CP1500PFCLCD; circa 2014]
It's not even shown in their 'PowerPanel' software."

Thanks so much for all the help! It looks like at present I've at least got
a working configuration that I need to test and fine-tune, am I
interpreting this correctly?

Yes. If you're good with the default NUT behavior of shutting down when the
UPS signals LB (low battery; per upsc, seems to be at 10% charge or 300 seconds
left, whichever comes first), it's just a matter of testing the shutdown
command, and any power sequencing (including any auto power-on settings on the
motherboard) issues on the way back up.

If not, there are ways to either adjust the UPS low power thresholds, or ignore
them completely. Roger Price has a good enumeration of alternate shutdown
strategies in his Configuration Examples document linked here:

As I just mentioned in my reply to Gene, it would be handy to have the output of
"upsrw" and "upscmd -l" for your UPS. Those commands show
the read/write variables and instant commands that the NUT driver detects,
respectively.
