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.
