Panel Lift Garage Door Mount for Shelly BLU Door/Window Sensor

Shelly makes a BLE magnetic sensor for fitting to doors and windows to detect whether they are open or closed. I use these with Home Assistant. To use these sensors with my panel type garage doors I designed this adapter which is mounted to the top panel on each garage door. When the garage door panel is vertical (the door is closed) the magnet is near the sensor and it reads as closed. When the door is raised along its track, the panel and the attached sensor mount tilts, and the magnet swings away from the sensor which then reads as open. The sensor designation is "Shelly BLU Door/Window" sensor. Enclosed are two STL model files and eight photos showing assembly, mounting and operation on the garage door.

The procedure is:

1. Print the two model files - PLA, no supports needed. Parts are in photo 01.

2. Hinge the magnet swing to the base using 2 x 2.5mm dia. self-tapping screws - do not tighten completely. See photo 02.

3. Mount the sensor with arrow up on the base as shown in photo 03, and the magnet on the swing pad using the self-adhesive pads that come with the Shelly sensor.

4. Activate the sensor by pulling out the battery tab - photo 04.

5. Ensure the magnet swings freely as shown in photo 05. Also check that the sensor is detecting the magnet correctly - in Home Assistant, the Shelly app or other compatible software.

6. Mounting on the garage panel (upper panel is recommended for best detection of opening and closing) using a couple of self-adhesive pads. Using a self-tapping screw is optional if mounting on the door frame. Pads are recommended to give further distance of the magnet from the garage panel so it doesn't stay stuck to the steel. See photos 06 and 07.

7. when the garage door is lifted and the panel rotates the magnet should swing down and away from the sensor. See photo 08.
