I’m in the exact same boat. I have a Jellyfin server configured and ready to go whenever something happens to really piss me off. This nearly was it until I saw that my lifetime Plex pass I bought 10 years ago will make it still be free for my family.
Why is your Roku TV even on the Wi-Fi if you just block its internet?
It’s probably that. While on cellular my IP isn’t 192.0.0.4 (but it is in 10. space), but there’s probably some v6 somewhere in the way.
I can’t get it to have network connection while my phone is on cellular data. On wifi it’s fine.
I used mostly this, but had to customize it a bit I think to get things working right. NUT feels like a super finicky system, but in the end it does work. My biggest issue right now is that it only reports a new status update to Home Assistant every few minutes, so the actions don’t really get a chance to trigger before the server shuts down. It also shuts down with the UPS at way too high of a percentage remaining, so I need to figure out how to make it wait just a little bit longer before the power down. It wants to power off like < 2 minutes after the power goes out…
I’ve got a project to look forward to. Have my Proxmox server with a UPS, running NUT to watch the battery percentage and power down gracefully if the % gets too low. I have Home Assistant watching that so it’s supposed to notify me before that happens. It’s not notifying me though, so I gotta look into that. I know it’s not working this morning because the power went out, so now I’m just sitting here theorizing instead of actually looking at it. 🙃
Great! I’ll use Button Mapper to remap that button to open Plex (or Jellyfin if I end up committing to switching to it).
