I remember there being a few. Let me check what I’m using and I’ll updated this post.
Ok. So I used homebridge-chamberlain
https://www.npmjs.com/package/homebridge-chamberlain
I remember now selecting this one because you don't have to mess with ApplicationID and it's just a little simper to set up than home bridge-myq as a result.
Testament to how stable all this is: I couldn't even remember the directory I installed it in on the Pi. I just never have to touch it!
Awesome! Now I need to get me some Raspberry Pi or a MacMini so the Homebridge won’t disengage every time my iMac goes to sleep.
Sorry for the detour everyone!
