Sommer Pro+ to ESP Adapter (Wemos mini boards)

This project lets you control a Sommer Pro+ garage door using a printed circuit board that's easy to solder thanks to only through-hole components and a plug and play design. The board simply clips into your wall control.

Features :

• Control opening and closing
• Retrieve door open or closed status
• Retrieve the status of the carriage lamp
• Forward original Keypad and Light connector

Compatible doors : S 9050 pro / S 9050 pro+ / S 9060 pro / S 9060 pro+ / S 9080 pro / S 9080 pro+ / S 9110 pro / S 9110 pro+

**Compatible boards: ** D1 mini (ESP8266), D1 mini Lite (ESP-8285), S2 mini (ESP32-S2FN4R2), C3 mini (ESP32-C3FH4), S3 mini (ESP32-S3FH4R2)

Tip

If you are looking for a Zigbee or Thread version, you can easily use a ProtoBoard to adapt the D1 pins with another smaller ESP32-C6 or ESP32-H2 board.
