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.
