Hey everyone, I could really use some help here. Just picked up a new Aqara door sensor (the MCCGQ11LM one), and for the life of me, I can’t get it to pair with my Hub M2.
I’m not a total newbie, but I’m definitely not a pro either—let’s call it enthusiastic beginner level. I’ve tried resetting the sensor (held the button until the LED blinked), set the hub to pairing mode, but nothing shows up in the app. It just keeps blinking and then gives up.
Hub firmware is up to date, plenty of Zigbee devices already connected and working like a charm, so it’s not a range issue (sensor is literally 2 feet away from the hub during pairing).
Is there some hidden trick I’m missing? Do I need to sacrifice a goat under a full moon or something to get this thing to connect? 
Appreciate any guidance or weird voodoo rituals that helped others get past this!
@ThermoTamer It sounds like you’re going through quite an adventure with your Aqara door sensor! Let’s see if we can untangle this mystery together. 
Firstly, you’ve done a great job ensuring that your hub firmware is up to date and keeping the sensor close during pairing. Here are a few additional steps that might help you get that sensor connected:
-
Check the App and Hub Status: Ensure your Aqara Home app is also up to date and that the hub is in a powered-on state. You can verify this by checking the indicator light on the hub.
-
Power Cycle the Hub: Sometimes, simply restarting the hub can resolve pairing issues. You can reset your Hub M2 by pressing the button for more than 10 seconds until the light flashes. Once it restarts, try pairing the sensor again.
-
Confirm Pairing Mode: Make sure the sensor is definitely in pairing mode. If the LED is blinking as expected but not connecting, try holding the reset button for a bit longer to ensure it’s in the correct mode.
-
Reduce Device Load: If you have a lot of Zigbee devices connected, remember that a hub can support up to 32 child devices. Double-check you’re not exceeding this limit.
-
Network Check: Verify that your hub is connected to a 2.4GHz Wi-Fi network. If your router supports dual-band, temporarily disable the 5GHz network to see if that helps.
If despite these steps the sensor still refuses to join the party, it might be worth reaching out to Aqara’s support for further assistance. Sometimes a fresh perspective can reveal hidden solutions.
Hopefully, these tips will help you avoid any further goat sacrifices! Feel free to share how it goes or if you discover any other tips or tricks. Good luck!
