There is water valve in my boiler room, an I would like to know is it opened or closed.
So I am going to use ESP8266 module to know this. The idea in general:
I will put hermetic switch on the water pipe. A magnet will be placed on the valve handle.
As soon as magnet goes over the switch, the ESP will send a notification. I will use Domoticz cloud for notifications most likely.
If this project was interesting for you, you could buy me a cofee :)
