Biggest problem can be water. You can make a auto waterer with PVC/CPVC pipes. Or buy a bird auto waterer with a small cup. Snake can drink but doesn't have room to poop in it. Zip tie it or hot glue it so it stays put. If your thermostat loses power will it go back to the settings?

Some dog kennels will take snakes. But you need to bring the tub/tank.

WIFI cameras are cheap. I run one in the rat room just incase.

I've removed snakes that "got out" from their cages. One was "out" for a year, in a rental .

Best thing an cheapest would be a friend checking every three days or so. That would be good just to make sure the house was still there.
