Or maybe not automate destructive devices. Might be simpler and more responsible anyway, since equivalent harm can be had if your kids ask Siri to warm up the house...

Automation bugs are dangerous on any home device. I once accidentally programmed an infinite recursive loop on all the lights in the house so had on and off signals being sent nearly simultaneously. Scary and not a good thing but easy to do particularly with wifi and mqtt messaging. Had to shut main power off. Luckily only one light switch broke.
