I had a couple stuck on walls where I always wished I had put light switches. They toggled lights on and off using ESP-01 microcontrollers. Another one was in my daughter’s bedroom where I had rehung the door to swing the opposite way so she could leave the door partway open without the hall light shining in her face in bed. As the batteries died I replaced them all with buttons run by newer ESP32s… if any of that makes sense.
That’s pretty cool! What would you use them for?
