In response to Relicense under an OSI approved license · Issue #2 · Genie-Garage/aladdin-python-sdk · GitHub I decided to cobble together a ESPHome-powered wireless* garage door remote. (*=Wireless in respect to the doors. The device is USB-powered 
). This is really hacky in my opinion, but I really hope it inspires others to take it to the next level (if you do, please share!).
I think my favorite part about this is that the remote is powered by the ESP8266. The final product is powered by a 4-inch micro-USB cable from my Home Assistant Yellow.
Parts
(all links are for reference. I recommend shopping around if you plan to attempt this yourself)
- Wemos D1 Mini (ESP8266)
- Adafruit Perma-Proto Quarter-sized Breadboard PCB
- Genie G3T-R remote
- THIRDREALITY Zigbee Smart Garage Door Tilt Sensor ← Any HA-compatible tilt sensor will do.
- 2.54mm/0.1inch Pitch 2 Pin screw terminal.
- Some right angle, 2.54mm/0.1inch Pitch headers
- 22 AWG solid-core wire. This is how I made “pins” on the garage remote, and made the “traces” on the proto-board.

Final product

Inspiration to make this came from Flipper Zeo Genie Recorder. After seeing how they used a Flipper Zero GPIO to control the remote, it just made sense to make this.
