was it ratgdo by chance?

40 bucks, HA, and about half an hour each (mostly fiddling with the ESP/shield pcb wiring inside the light cover of the opener from the awkward overhead-on-a-ladder position) for me to no-cloud smartify two chamberlain MyQ openers. Special sauce is that the device can MITM the "Security2.0+" signal and emulate the discrete functions of the wired wall remote, not just act as a dry contact relay on the motor.

Result is that separate entities are created not just for the door open(ing)-clos(ing) states, but also for the obstruction sensor and a separate switch to turn the opener's light on or off remotely, all exposed (as MQTT topics) in HA.

This looks like what I want. I’m confused though: what is the radio? WiFi? Zigbee?

[ChainOfFools]

Yeah sorry, it's Wi-Fi. It talks to an mqtt broker and that's how home assistant sees it. or anything else that also talks mqtt.

Perfect, thanks!
