Upgrade your garage door opener with the alternative to ratgdo F Chamberlain. This new product is a great alternative to the Ratgdo and less costly. With its advanced features, you can easily connect it to your home WiFi network and control your garage door from anywhere using home assistant or home kit. If you add it to home kit, you can even use siri!

The pcb is designed to work with Chamberlain (yellow learn button) or Liftmaster 2.0 (yellow learn button). Note, the jackshaft wall mounted 8500/RJ020 & 8500C/RJ020C have a yellow learn button, but they use Security 1.0 protocol and will not work. This pcb can work with Security 1.0 (purple learn button) but it remains experimental and no support is provided.

This pcb comes with no firmware. You will have to setup yourself. This pcb will work with paul's firmware, other firmware, or the homekit firmware.

You will receive the 1x circuit board and d1 mini. You will need a microUSB wire. All circuit boards are tested before being sent out.

Shipping can be combined if you want more than 1 unit.

This pcb does NOT include a transformer on this board. Please see v2.5 in another ad if you want a transformer which will allow you to power it using a 6v to 30v battery from your chamberlain or liftmaster battery instead of a micro USB.
