Why This Happens in Real Homes
If the Meross opener shows Unknown status, the door sensor is usually misaligned. This guide checks sensor placement, wiring, and app settings to restore status updates. In day-to-day use, this usually looks like App shows Unknown status; Door opens and closes; Sensor LED off.
Most cases trace back to Sensor magnet misaligned; Sensor wire loose; Sensor mounted on wrong panel. The fix works best when you go step by step instead of changing multiple settings at once.
A practical order for this issue is: Check Sensor Alignment -> Inspect Wiring -> Verify Mount Location -> Test in App. After each step, test the exact behavior that was failing so you can confirm what actually solved it.

Use cable clips to keep the sensor wire from snagging on the door track.
This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.
