The Smart Garage Control is compatible with most garage door opener brands manufactured starting January 1, 1993 and that have photoelectric safety sensors. Check opener compatibility by manufacturer.

Router compatibility and settings

2.4 GHz is enabled, 5 GHz is NOT compatible
802.11g or 802.11n (802.11 b/g/n) is enabled
DHCP is enabled.
Security is set to WPA2.
Inbound and outbound /TCP port 8883 is open

See more information about router settings and compatibility here.

How to improve your Wi-Fi signal

The Wi-Fi signal in a garage can be diminished because of the structure in the walls. If you have a weak signal in your garage, try the following:

Make sure the router is within 50 ft. of the hub.
Move the router closer to your garage to minimize interference from walls and other objects.
Use a Wi-Fi extender, see a list of tested Wi-Fi extenders.
Use a LiftMaster ® Internet Gateway model 828LM.

Test the door sensor battery

Test the door sensor battery every 6 months or if the Smart Garage Control is not working as expected.

Press and release the test button on the door sensor. The red LED on the door sensor should blink and the hub should beep.
Wait 5-10 seconds, then repeat this test 5 more times (wait 5-10 seconds between each test).
If the LED doesn’t blink or the hub doesn’t beep with each press, try the following:

Make sure you remove the pull tab from the door sensor.
Debris may be present on the battery. Remove the sensor cover and slide the battery out to check.
Replace the battery, see Accessories and Parts.

Change the door sensor battery

Pry the latch panel on the bottom of the door sensor with a coin or screwdriver and lift the top to remove it.
Using a soft non-conductive tool (such as a cotton swab), gently push the coin battery out of the clip.
Gently but firmly insert the new battery into the clip and replace the cover.

Dispose of batteries properly. Replace ONLY with 3V CR2450 coin batteries, see Accessories and Parts.

Erase Wi-Fi settings from the hub

Erasing the Wi-Fi settings allows you to reset the Wi-Fi settings on the hub.

The green LED MUST be on or blinking to erase Wi-Fi settings.
Press and hold the button on the hub until the blue LED blinks.

Reset the hub to factory default

Resetting the hub to factory default will erase the Wi-Fi settings, and removes the device from the myQ account.

Press and hold the button on the Wi-Fi hub until the blue LED blinks then release.
While the blue LED is blinking, press and hold the button again until the blue LED pauses then blinks or beeps. The Wi-Fi hub is set to factory default.

To install and connect the hub, see Connect Your Smart Garage Control.

Update my network settings in the myQ App

When you replace your router or update any of your home network settings or password, you need to update the settings in the myQ app and reconnect your Smart Garage Control.
