How to keep lights out after bedtime?

Different families have different use cases. I personally don’t see this as “Weaponizing,” families have used multiple methods for keeping little kids from turning switches on and off for literally generations. You can buy dozens of babyproofing switch locks at Home Depot, Walmart, or on Amazon now, they just aren’t smart.

My only concern is that most of the dumb ones have a method that allows an adult to still use the switch when needed.

If you use a smart switch cover, you’ll still have that option with many models . But otherwise it could get tricky.
