Compatibility Check
Before installation, ensure your existing myQ Smart Garage Hub is model MYQ-G0301 or 821LMB. This add-on sensor will not function with older myQ Garage models (MYQ-G0201 and 821LM).
Installation Steps
- Download the myQ App: If you haven't already, download and install the official myQ app on your smartphone or tablet.
- Prepare the Sensor: Ensure the included Lithium Metal battery is correctly inserted into the sensor.
- Mount the Sensor: Attach the myQ-G0302 sensor to the inside top panel of your second garage door. Use the provided installation hardware (bracket or Velcro strips) to secure it firmly. The sensor uses tilt detection, so proper orientation is important for accurate readings.
- Add to myQ Account: Open the myQ app and navigate to the device setup section. Follow the in-app instructions to add the new door sensor to your existing myQ account. This typically involves scanning a QR code or manually entering a serial number.
- Pair with Smart Garage Hub: The app will guide you through the pairing process with your MYQ-G0301 or 821LMB Smart Garage Hub. This may involve pressing a program button on your garage door opener motor and confirming the connection in the app. The garage door may open during this process to confirm successful pairing.

Operating the Sensor
Once installed and paired, the myQ-G0302 sensor integrates seamlessly with your myQ Smart Garage Hub and the myQ app. You can:
- Monitor Door Status: View the real-time open or closed status of your second garage door directly from the myQ app.
- Open/Close Remotely: Control your garage door from anywhere using the myQ app.
- Receive Alerts: Set up custom notifications to be alerted when the garage door opens, closes, or remains open for a specified duration.

Please note that each myQ Smart Garage Hub is limited to controlling two garage door openers. This add-on sensor is intended for the second door.
Maintenance
Battery Replacement
The myQ-G0302 sensor operates on one Lithium Metal battery. The myQ app will typically notify you when the battery level is low. To replace the battery:
- Carefully remove the sensor from its mounting location on the garage door.
- Open the battery compartment, usually located on the back or side of the sensor.
- Remove the old battery and dispose of it according to local regulations.
- Insert a new Lithium Metal battery, ensuring correct polarity.
- Close the battery compartment and re-mount the sensor securely.
Cleaning
Wipe the sensor periodically with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners, as these can damage the device.
Troubleshooting
- Sensor Not Connecting/Pairing:
- Ensure the sensor battery is not depleted.
- Verify that your myQ Smart Garage Hub (MYQ-G0301 or 821LMB) is powered on and connected to your home Wi-Fi network.
- Confirm the sensor is mounted correctly on the garage door.
- Try restarting the pairing process through the myQ app.
- Delayed Response or Intermittent Connectivity:
- Check your home Wi-Fi signal strength in the garage area. The hub and sensor require a stable connection.
- If you recently changed your Wi-Fi router or network settings, you may need to re-establish the connection for your myQ Smart Garage Hub. Unplug the hub from power for a minute, then plug it back in and follow the app's instructions to reconnect.
- Ensure there are no significant obstructions between the sensor, hub, and your Wi-Fi router.
- App Display Issues (e.g., cannot open/close in list view):
- Some app versions or display modes may have specific functionalities. If you encounter issues, try switching back to the default device view (e.g., side-by-side) within the myQ app.
- General Issues:
- Refer to the myQ app's help section or the Chamberlain support website for detailed troubleshooting guides.
- Ensure your myQ app is updated to the latest version.
