PLM 2413S status in programs

[FBoucher]

My Polisy is currently powered by a CyberPower UPS and I'm exploring ways to get notified when my Polisy is on battery and have a few hours or less of operation. The use case is rather simple. In case of being away for a weeks/months, I would have to alert a close friend that I need home surveillance. So:

1. Is it possible for my Polisy to communicate directly with the UPS? On the UPS, there are RS232 and USB connectors. There is also a software provided by CyberPower that allows status feedback to a computer. Any way to integrate?

2. For my Insteon devices, I have a PLM 2413S connected to my Polisy via the DB9 port. The PLM is directly connected to my house electrical grid. During a power outage, the PLM will stop communicating with the Polisy. It looks like the PLM is not listed as part of the nodes. Is there a way to monitor the PLM status in programs?

3. If I can't use the PLM status, is it possible to monitor another Insteon device for an "unknown" status?

4. Other ideas?

Home Assistant.  I run the NUT (Network UPS Tools) which appears to have most cyber power units on it's hardware  compatibility list.    The UPS plugs into the Pi running HA, and various items show up as entities in HA.

I'm not using Cyberpower but here's what I'm getting from my APC:

Most of which I don't actually use...

I also have HA updating a State Variable in ISY.... I haven't finished building it out yet, but the purpose to make sure lighting is where is should be after power restore.  Insteon returns to it's previous state, but if we passed into another time period things may not be correct.

I suppose your HA on Pi also runs on your UPS. For now, my HA is a VM on my Media server that is not running on UPS. I can probably move it to my File server that is running on UPS but running low on RAM. I'll give it some thought.

Would you know of other solutions?

I don't, I fought with that issue for years.  Until I added the NUT add-on.   The NUT server doesn't have to run on the same machine as the HA and the NUT integration, but it wouldn't make sense to have HA go down when the power was out.

True, especially if HA is part of the solution.

NUT can also run on a firewall-router running pfsense, possibly others.

That's true, but part of the problem above was that HA itself wasn't running on a machine with backup power.
