Why does the Meross app show the garage door as open when it's closed?


You can troubleshoot as the following steps:

1.Make sure the two magnetic sensors are close to each other, within 3cm(1 inch), when the garage door is fully closed and vice versa;

2.Unplug and plug the sensor cables, check there’s no any wire damage;

3.Do not install the sensors directly on any metal rails. For instance, you can use the material such as PVC to isolate the sensors from metal to avoid magnetic interference.

4.Factory reset the smart garage door opener and set up it from the scratch.

5.Completely reinstall Meross app.
