Liebert UPS Communication/Service

[JaredG]

I've got HexOS installed and working great so far! Now I'm wanting to set up some conditions that will shut down my system before my UPS runs out. Or at the very least safely shut down on battery operation.

From the research I've done so far I know that this is something I'll have to set up in the TrueNAS UI>system>services section. 

I've found the NUT compatibility list and my UPS is not explicitly listed (Liebert PST5 850VA/500W); however, I would like to do some testing to see if I can get any of the drivers working. 

I'm not very familiar with the TrueNAS shell yet so I'm not sure how to go about testing this. 

Looking for some direction or references about where to start, or how to go about this.

Thanks!

wish i could help but that compatibility list confuses me too, i never got around to even purchasing a ups because of it.

@JaredG Out of curiosity do you have Home Assistant?

I personally ended up connecting my UPS to this and then i use the truenas integration so i can shut it down with automations if needed. As i had a lot of issues with the UPS setup in truenas and i think at one point there was a bug where it wouldn't show any telemetry.

@Mobius its too bad there isn't a more common UPS standard for network devices. I bought this UPS well before even thinking about building a NAS, compatibility wasn't a concern then. Weird we go through all the work of making our storage drives redundant but the actual power is less of a concern. 

@Theo Unfortunately, I don't have home assistant, I'm invested in a couple different ecosystems so porting all my hardware over to a new platform isn't a priority for me yet. That is a clever work around though! How are you implementing HA? I've heard that having a separate system is more stable than running it in a VM.

funny enough im less worried about my power going out than i am worried about a family member turning off or unplugging my power strip.
You'd think a heads up to not touch this outlet that is in a super hard to reach place would be enough.

So i personally have HASS running on an RPI5. And have the NUT Server + Client running on that seamlessly (Once set up, again docs are not ideal, had to manually specify the usb port.) 
I started my HASS journey running on a VM on a mac mini, but prefer running bare metal for stability sake, and simplicity of attaching devices.

But when i set up my remote Hex server at my parents, i installed HASS on the VM inside the TNUI (Tried the App, but too many network issues) + VM is super easy to passthrough the usb device for the UPS + A zigbee dongle.
