I have a bunch of things at the office set to automatically turn off at a certain time or on command. It's helpful in that I don't leave something running that really shouldn't be, like a laminator, overnight. After that I decided to put an Alexa plug on anything that could potentially be a fire hazard if left on, like the air purifiers and fans.
It's hardly a bulletproof solution but it's better than the old solution of, "Oh shit, I think I left X running… welp, time to waste 40 minutes driving back and forth."
