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.
There isn’t a standard that is broadly-adopted, but NUT (https://networkupstools.org/) has reverse-engineered drivers for nearly every UPS out there, usually each brand has their standard so as long as the brand is supported it will work. (NUT is also what TrueNAS, Synology, QNAP, etc use internally for their UPS support)
I’ve had good luck with using NUT with APC UPSes (both consumer models and buying used enterprise rack-mount models).
One cool thing you can do with NUT is share the UPS state over the network, so that multiple machines can respond to the power state instead of just the machine that is plugged in via USB directly.
