From what I understand the TrueNAS web ui does not have support for monitoring or controlling more than one UPS. Are there any guides for how to do this? I feel like this may be a common issue. I've searched these forums and found a number of posts about it.
My understanding is that you would have to install NUT as primary / master on another device like a pi, nuc, pfsense router, etc. and configure a dummy UPS that shows the higher battery status of the two UPS's. Then in TrueNAS, you setup as secondary / slave and monitor the dummy UPS to handle the shutdown.
In my case I have a pi setup as the master monitoring 3 UPS's. All UPS data cables plugged into the pi.
1 UPS "network1" powers the modem, router, pi, switches.
2 UPS "servers1" and "servers2" power the servers. (2 servers, dual PSU, 1 PSU into each UPS)
So far, I have the pi correctly monitoring the UPS's.
I have not setup a dummy yet as I wanted to confirm that is the correct / recommended way to do it.
If anyone has done this for the APC BGM1500B I'd certainly appreciate any help you can provide.
Also, does TrueNAS gracefully shutdown any VM's and Jails during a NUT system shutdown, or do you need to create a custom shutdown script to do that?
