Hi guys,
I have a water heater with a mechanical stem thermostat inserted at the bottom.
I want to put a small DS18B20 thermostat on top of it and connect it to a sonoff th16 so I can read the data.
I bought a bunch of DS18B20, a 3.5mm jack terminal and took the wires from an ethernet cable.
Than I connected them according to this info:
I tested the entire installation on to see if it works, but there was no reading and the DS18B20 heated really bad (burned my finger).
Am I missing something? it should be a really simple circuit…
Thanks!
Naor
