- Sensor magnet reversed

Problem Description
A reversed status usually means the sensor magnet is mounted backwards or on the wrong panel. This guide fixes sensor placement and updates status.
Why This Happens in Real Homes
A reversed status usually means the sensor magnet is mounted backwards or on the wrong panel. This guide fixes sensor placement and updates status. In day-to-day use, this usually looks like App shows open when closed; Status flips incorrectly; Door opens and closes.
Most cases trace back to Sensor magnet reversed; Sensor mounted on wrong panel; Sensor gap too large. 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 Magnet Orientation -> Mount on Top Panel -> Reduce Gap -> Test Status. After each step, test the exact behavior that was failing so you can confirm what actually solved it.

Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Use cable clips to keep sensor wires away from moving parts.
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.
