really impressive that you managed to do that in an evening. would be interesting to see a more lenghthy video of your process to arriving at the method that controlled the timming. I imagine you arrived there by tracing the button to the GPIO on the STM and the looked for functions that where using that particular pin based on the STM memory map?

Cool fix.

Was really hoping we would get a RV fan we could use with Home Assistant and/or Nodered

Hi, i stumbled on your channel looking at CAN bus videos. looking to intergrate a fan very similiar to this one. (hatch open and close, fan in and out, and fan speed) how easy would it to to perform those signals through CANbus? is this possible through firmware or installing a relay board to control those signals.

Nicely done any chance you can show the motor I wonder how easy it is to add a motor and Arduino to a manual window

what manufacturer :-P and how much? looks like a neat shed fn if you have 12V solar system/batteries
The onboard LED shoud light if the motor is actuated to show problems with the gearbox and lever :-P
