 The firmware radio decoding is inspired by 1) RF-Bridge-EFM8BB1 (Portisch) and 2) rc-switch projects.

+THIS IS A WORK IN PROGRESS and should not be used by typical users.  
+
+Erasing and reprogramming the microcontroller is cumbersome without the official programmer.  
+I am using the microcontroller as a pass through to ESPHome now.  
+So the code is a mess for selecting other uses.  
 
 That said, decoding of protocols 1 and 2 seems to work reliably.  
 For example door reed sensors - both stock and modified - have been successfully decoded.
