Calibrate the Optical Laser Sensor in Home Assistant

How to calibrate the Garage Door Opener's optical laser sensor that sees if the door is open

Home Assistant users of Konnected's Garage Door Opener can calibrate the optical laser sensor directly from Home Assistant with a simple one-time service call.

After you've mounted the device on the ceiling of your garage and connected and tested the garage door control wire, you can calibrate the distance between the ceiling and the top of your garage door when it's open.

Calibrate the Open Garage Door Distance

1. Make sure that the device is mounted on the ceiling in its final position.
2. Open the garage door. The garage door should roll up directly underneath the device.
3. Open Home Assistant > Developer Tools > Services. Start typing "calibrate_open_garage" and the full service name including your garage door opener's unique name should auto-compete:
   
   
4. Click Call Service. Your device is now calibrated!
