My sensor or departure switch is not detected by the gateway. What should I do?

Remove the batteries, press any of the remote buttons, and reinsert the batteries. You should see a green light blinking on the front of the remote to indicate that it is correctly powered. Install new batteries if you don't see the light, or if it is weak/dim.

 

For connection issues, place the sensor/switch closer to the gateway (20-50 cm) during the detection procedure.
