For that, I’d highly recommend a power conditioner with outlet controls (and preferably sequencing).
Most are pretty expensive, but you can get something like a surgex squid or a gude expert power control for a few hundred here and there, which will give you great data on power usage as well. You can also grab an older model with serial and/or relay controls, and use a pi or whatever is handy to trigger it. Actually have a setup like that in a few racks for clients (mostly orange pis and a couple of Asus tinker boards).
Hope your trip goes well!

This is something that even larger corps struggle with. My old company would buy some other company, lay off a bunch of people, others would quit, and then it was shocked Pikachu faces all around when That One Thing stopped working in an office they turned into a ghost town and, well, no, nobody was going to be there until Monday morning to power cycle etc. True lights out/OOB reachability is WORK. And there’s always going to be a SPOF somewhere that requires hands on-site.
Do what you can, when you can. And thank you for all that y’all have done so far.
