I, too, installed an open source garage door opener, and I’m loving it

This is not egregious behavior, at least on the scale of garage door opener firms. And Aladdin’s app works with Google Home and Amazon Alexa, but not with Home Assistant or my secondary/lazy option, HomeKit/Apple Home. It also logs me out “for security” more often than I’d like and tells me this only after an iPhone shortcut refuses to fire. It has some decent features, but without deeper integrations, I can’t do things like have the brighter ceiling lights turn on when the door opens or flash indoor lights if the garage door stays open too long. At least not without Google or Amazon.

I’ve seen OpenGarage passed around the Home Assistant forums and subreddits over the years. It is, as the name implies, fully open source: hardware design, firmware, and app code, API, everything. It is a tiny ESP board that has an ultrasonic distance sensor and circuit relay attached. You can control and monitor it from a web browser, mobile or desktop, from IFTTT, MQTT, and with the latest firmware, you can get email alerts. I decided to pull out the 6-foot ladder and give it a go.

Installing the little watching owl

You generally mount the OpenGarage unit to the roof of your garage, so the distance sensor can detect if your garage door has rolled up in front of it. There are options for mounting with magnetic contact sensors or a side view of a roll-up door, or you can figure out some other way in which two different sensor depth distances would indicate an open or closed door. If you’ve got a Security+ 2.0 door (the kind with the yellow antenna, generally), you’ll need an adapter, too.
