ratgdo [https://paulwieland.github.io/ratgdo/] already exists and works great.

For the current roadblock, it appears it was due to cloudflare bot protection [https://community.home-assistant.io/t/the-current-state-of-m...]

I haven’t previously heard about the ratgdo, but I recently did this myself with an ESP8266, relay, garage door remote, and Tasmota for the firmware. It works flawlessly with MQTT/Homeassistant. The individual components (excluding the opener) are < $10.

You are missing the beauty of the ratdgo. The ratdgo has open source firmware that implements the encrypted serial communications needed to control and get status (open/opening/closed/closing) from Chamberlain / Liftmaster garage doors (without needing the myQ hub).

Ordered it, thanks. I saw it in the article too.

Glad people like this exist.
