What to know before buying

Compatibility is model-specific. Check the garage opener against meross's compatibility list before buying. Setup calls for a 2.4GHz Wi-Fi network with a strong signal, and the listing says the two sensors should be less than 1 inch apart when the door is closed. The unit connects by wire to the existing opener.
