URGENT Heater Help Needed

Hi elm

There is a "strange" implementation of the keyfob functionality. You start the preheat by pressing the button twice rapidly and the preheat starts. Sometimes.

Have fun resoldering

Very good info .. thanks again.

I was already DIY some electronic over arduino/STM32 baords, RF modules and different type of sensor modules .. so .. I'm fully prepared for the soldering job ... worst case .. I waste one of my two keyfob

My main idea was to be able to pre-heat before the program pre-heat start (for get 20min pre-heat on the coldest morning) .. so clicking from home without looking at the car .. so maybe at the end it will not work .. anyhow .. it sounds a easy and "fun" project.
