Bought a second sensor (MyQ-G0302) for my other garage door from Walmart and the documentation says it is compatible with both MyQ Garage (G0201) and MyQ Smart Garage Hub (G0301). The hub led flashes but does not beep when I press the test button during the setup. After that the hub shows yellow light blinking whenever I press the test button on the sensor. But cannot get the app to add the new sensor. Pl. help.
