How to add a UPS to my bare metal HA unit

Configuration
1

I’m running Home Assistant in a bare metal NUC 11 box and trying to find a way to power the box via an APC UPS. My problem is that I can’t find any way to configure shutdown options in HA? I see some posts regarding using NUT to shutdown VMs and dockers from a UPS being monitored over the network but for my situation I will have the UPS connected to the HA appliance via USB serial cable and monitored directly by HA. Is this possible?

Yes - assuming HAOS. Mine does this.
Set NUC to boot on power up.
Run nut addon on haos.
Use nut integration to connect to nut addon
Plug in USB set automations for your shutdown threshold.

If not haos you’ll need to run Nut - probably in a container.

I don’t see any boot on power up setting in HA. Where do I set it?

Edit: Is this a bios setting?

That’ll be a BIOS setting.

Thanks, so Network Ups Tools integration/plugin will work even if there isn’t any network involved?

Yes. (with more than 10 characters for the post)

Check the social section. I made an entire video all about what you’re trying to do - even for a NUC. :slight_smile:

Thanks but search seems to be broken. No matter what terms I use I get exactly the same results and none seem to be relevant.

There’s an entire thread with no one but me posting in it. Shouldn’t be that difficult to find…

Finally got a chance to get everything setup. Addons and integrations are installed and working. I see entities that suggest they are settings to control when the host gets shutdown and restarted but the docs don’t have any info regarding details on any of these entities. I’m looking to shutdown the host at a battery charge level of say 30% and boot the host when power is restored for 60 seconds. What configurations do I need to adjust for this?

Also, thanks to @exx for the video.
