I may have gone slightly overboard with the home automation. I have added my daughter's hamster to Home Assistant.

(also, that lil' guy can run!)

@grapefrukt hello, may I ask how you did this? Thanks.
@nya_su esphome on a little microcontroller with wifi hooked up to a ir distance sensor. the wheel happens to be black so i put a piece of white tape on it and tweaked the sensitivity of the sensor so it triggers on the tape. that's it!
