The Internet of Garage Door Openers

While RF remote garage door openers are pretty neat, if you want to control it via the web or MQTT, then the GaragePack by ‘achmed20’ looks like a very good solution. A Wemos D1 mini ESP8266 board is used for control, along with a relay to actually trigger the door and an ultrasonic sensor to determine the state of the door. A PIR sensor can also be added for a security system and/or to automatically turn on lights, and theoretically such a system could be expanded however you like.

The Wemos board powers everything here, so if you’d like to build one yourself, you’ll just need to make the proper connections and insert them into the excellent 3D-printed case. Once assembled, the device should be mounted above the garage door, so that when it rolls up it senses the door reflecting the signal. Presumably this would preclude the use of the PIR sensor unless remotely mounted, though if you have your door open, you’re probably not too worried about intruders at that instant.

The web interface for the project is refreshingly simple, with a big gray icon to open and close the door. The icon also shows the door status and whether movement is detected. Files for the build are available on GitHub.
