rat-ratgdo

Second this product. I wanted an Ethernet version so I made my own (it's integrated into esphome and the circuit is documented here https://github.com/Kaldek/rat-ratgdo). Apart from general usage, I use mine to tilt the garage door a small amount if it detects bad air quality in my shop (using an IKEA air quality sensor via home assistant).

Left out is a bit of the saga of ratgdo and that it's not actually open source hardware. There is a separate effort in that space - https://github.com/Kaldek/rat-ratgdo I have no issues with closed hardware and making money. However, the ratgdo maintainer will actively delete any references to other alternatives which I think is poor form and leaves a bad taste. Especially since his product relies so heavily on other open-source such as esphome, as well as the Security+2.0 protocol work that is out there (eg. https://github.com/argilo/secplus )

You may actually need a little bit of extra information to replicate a handful of traces (i.e.on breadbpard) present on the little PCB 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. It appears that this project has gone from a very minor side hobby an actual business for the author, and the PCB schematics are pretty much the only IP moat he has, without them he's just providing a very easily (and cheaply) replicated PCB assembly service. I believe, although I have not verified because I h
