get the status of your windows. sensor is between your handle and the window.
- replace xc6220 footprint with the one from KiCAD
- add a button for wifi reset
- battery connector rotate it: open should be on top
this project contains of two pcbs.
This PCB is the sensor. It has three hall sensors placed on a 0.6mm pcb.
