I was able to plug in my UPS and get it to kind of work. The only way I am able to tell it works is that when I unplug the UPS the system will automatically shutdown about a minute or 2 later. When I go to the reporting, there is nothing there. Are there auxiliary parameters that I need to set for the reporting to work correctly? I have the UPS connected over USB.
From an SSH/Shell window type: upsc ups and you should get a report of data from the UPS.
Doing that gives me the following output:
Init SSL without certificate database
Error: Unknown UPS
it should be upsc ups@localhost, at least that works for me
Edit: Nevermind, didn’t know upsc ups is enough to show the stats…
Doing either command does not give me any info, just the error I posted above.
What UPS do you have (make/model)?
Cyber Power CP1000PFCLCD (as in the title of thread)
What, you expect me to read? 
You should be able to ignore the first message. The second message means the UPS name is not “ups”. Try upsc upsmon as that could be a used name as well. If that fails try upsc upsmon@localhost
If that stuff fails…
What are your settings for the UPS Service? A screen shot goes a long ways. It is good that TrueNAS shuts down, but it is odd that you cannot communicate with it directly.
Still didn’t work. Added screenshot to original post.
I was able to find the list of UPSes connected by running the command upsc -L. That then gave me the connected UPS “Cyberpower-CP1000PFCLCD”. To then list the UPS settings I tried upsc Cyberpower-CP1000PFCLCD which worked. It seems its dependent on what you set the identifier as. Changing the identifier to “ups” the reporting started working. Not sure if that is a bug or just really poor documentation on the setup of a ups. I was following the official documentation when I set it up and they didn’t mention anything about the requirements for the identifier or the reporting being dependent on having the UPS named “ups”.
Is there a way to change the reporting to show runtime in minutes instead of days? Days is pretty useless, as I don’t know there is a UPS in existence that would have a runtime of days.
I already filed a bug report for that, I agree that “Days” so not a good value.
