I'm trying to "hack" my heating device.
I need to build a variable resistance controled remotely with Domoticz.
The goal is to send the value I want to put.
4500 -> 4500 Ohm
4200 -> 4200 Ohm
Any idea how to do this ? With Arduino ?
Explanations :
The outside thermal sensor is broken, a new one is way too expensive !
