 ### Pairing
 
 Pair the switch to Zigbee2MQTT by pressing the pair button (found under the back cover next to the battery) 4 times in a row within 5 seconds. The red light on the side should flash a few times and then turn off. After a few seconds it turns back on and pulsate. When connected, the light turns off.
