Will any UPS work with Linux? (lemmy.world)

I'm down to the last few hours of discounts here. I need to get my NAS and my server onto a UPS months ago. Both are already set to come back on when power restores. We rarely have power outages and have solar panels (no house battery though), so a full outage is even rarer.

I understand that a UPS can send a shutdown signal when power is lost. Is this a universal standard or format for this? If so, what keywords should i use when searching for compatible products? My father told me to look for one with Ethernet ports. I just want to make sure everything is compatible. I go out of town occasionally and as well as preventing data loss, I also need everything to go down and come back up automatically so I don't have to call a friend, neighbor, or my spouse to go mess with stuff for me.

UPS brands considered (alternatives welcome): APC, Cyberpower

Systems protected, Synology DS 220+ & BeeLink MiniPC running Debian 12.

Also, for anyone who has helped me out previously in my self-hosted journey, thank you! Things are going great and I have a few useful docker images running various services and have set up grub btrfs snapshots to easily fix my screwups. This community has been incredibly helpful.

I just bought a random UPS at MediaMarkt back in the day in Poland and calculated that it would be able to power all the CCTV cams, the CCTV recorder, a raspberry pi and the modem which is connected to a long range WiFi antenna for at least half an hour. This worked very well for a couple of years until the battery gave up. The one I had had a ethernet port but I never bothered to set it up to send the signal.

Mine was running at my parents summer house in Poland while my parents live in Germany and I in Sweden and now in Korea, so if something breaks down it's down for up to a year until someone goes there to fix it.

Right now everything is down, my dad was there a couple of month ago and said that a marten chew up the Ethernet cables. Sadly my dad couldn't fix it so now I hope I will be able to get there during Christmas.

Yup, batteries need to be replaced every 3-5 years. Make sure you account for that cost when purchasing.
