3. Add sub-devices
   Connect the Bridge before adding the sub-device.
   Access the eWeLink APP and select the Bridge, tap "Add" to select the alarm, and a "Beep" means the Bridge enters the pairing mode. Then seperate the magnet for more than 20 mm from the transmitter until the LED indicator stays on for 1 to 2s, and the pairing is complete when you hear "Beep Beep".
   If the addition failed, move the sub-device closer to the Bridge and try again.
