I built this “Thing” cause I wanted to monitor the temperature in my house while away in winter months. As you likely realize if your heater quits and your plumbing freezes … its a bad day!
I would upload a video to show it working but … well … I cannot!
Wait this works …
Next winter I plan to put one of these on my K40’s aquarium heater to keep the bucket warm, pump on and tell me the garage temperature even when I am away.
