rat-ratgdo VS OpenGarage-Firmware

You may actually need a little bit of extra information to recreate the little PCB board that the ratgdo software relies on to interface the espressif to the terminals of your opener.

It's not terribly complicated but for reasons that are polarizing to many in the garage-door-automation society, the author of the software, although leaving the code completely open source is averse to publishing schematics for the PCB board itself, so others have had to step in and reverse engineer these.

I believe, although I have not verified because I haven't tried this myself, that this site provides both the schematics you need as well as information necessary to Flash the software onto your ESP device.

Personally I went with OpenGarage https://opengarage.io/. I have been using OpenGarage for 3+ years now. It has been amazing.

If anyone is lazy, but wants the functionality and insists on open source….check out https://opengarage.io/ ($50) which offers similar functionality. I switched to a MYQ door opener which made the opengarage need obsolete, but I’ve been happy with MYQ - however it does require cloud access.

I switched to opengarage.io - after trying a few garage door automation devices that utilized door sensors.

I recently got some Matter-capable IoT lightbulbs to try, and I am not impressed. They seemed to have all the same problems I've experienced with previous IoT products (connectivity issues, state de-sync between device and "edge router", firmware updates take ~10 minutes per device).

Then there are problems specific to Apple's IoT stack - like how it's impossible to set an RGB capable light to a ~specific~ white color temperature. Instead you get a shade picker and you have to guess what the color temperature is.

The best IoT experience I've had is with OpenGarage[1] using regular old WiFi, but overall I'd still never rely on IoT products for anything critical.

I got a opengarage thing instead. No door sensor. Uses ultrasonic sensor to see if the door is open or closed. All one piece, hardwired to power. It's been rock solid.
