Have you implemented support for adding a second ultrasonic sensor to monitor two car garages? Since I’m unable to update my firmware OTA, I’m looking to replace it with a DIY one similar to this:
OpenGarage DIY
I’m also interested in seeing what your DIY solution looks like.
Support is close for an API only implementation of a second door monitor, something you can use with a home automation setup, Alexa or Apple Homekit but adding support for a second door into the UI or the Android app is quite significant and I suspect wouldn’t be a priority to ever incorporate into the official firmware. So my thought is to add it but in a compatible way with the official firmware so making it available only via an API call.
