Unfortunately that won’t work, as the heater goes through a start-up and shut-down process - so switching the 12v on and off would either just not work or break something.i would just use a mosfet or relay to switch the main 12v supply on/off
then some kind of temp sensor that the pi can interface with, to measure its temp
and then implement the entire thermostat logic on the pi
just slap a fixed resistor value where the pot goes, and turn the 12v on/off instead
If I keep the existing controller, I could just control the on/off and let the controller deal with the temperature. That is the simple (easy) solution, but I’d like to be able to do the temp via Raspberry Pi too - but appreciate it May be too difficult / not possible
