If you have a NUT server configured then you can depending on UPS vendor. My APC can and that’s how I pull it into HA.

A lot of UPSs will have power metering as well if you’re not already on one.

My rack server uses 150W idle. Granted that’s 2 processors and 48 cores, 256GB ram, and 8 case fans that you can’t cycle less than 35% even though they don’t need to be anywhere near that high.

Yeah, email is one of the more annoying things to self host. Google rejects mine because my ISP has all their non static IPs on block lists (even though my IP hasn’t changed once since I’ve been with them it’s still not “static”, can’t change the reverse DNS) and I’m not paying 150% more a month for a business account to get a static IP. I ended up just using a free email relay. Still had to setup SPF, DKIM, DMARC, and all that jazz still.

Compounding fines. If they’re not gone in a week double it and fine them again. Continue until they’re removed.
