Hey guys, I have been searching for a way to do this and coming up empty handed. I have a gfk-160a fireplace blower. On it there is what looks like a volume control knob to control the fan speed. It has two wires on it. I'm guessing this is an analog potentiometer.
How could I build something digital to control the fan speed from my phone or from Alexa?
The problem I have now is that in order to change the fan speed I have to take the front of the fireplace off to get to the knob. Bad design.
Hopefully you guys can help
