Why Is My Meross Garage Door Status Reversed in the App
- Sensor magnet reversed
- Sensor mounted on wrong panel
- Sensor gap too large
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.
Symptoms
- App shows open when closed
- Status flips incorrectly
- Door opens and closes
- Sensor recently installed
- Magnet alignment uncertain
- Status updates delayed
Recognize these? Here's what usually causes it.
Common Causes
- Sensor magnet reversed
- Sensor mounted on wrong panel
- Sensor gap too large
- Sensor wiring loose
- Firmware outdated
- Sensor needs recalibration
Most fixes happen in the first 3 steps.
Verify status after each adjustment before final mounting.

Step-by-Step Solution
Check Magnet and Sensor Orientation
The Meross garage door opener uses a magnetic reed switch sensor to detect whether the door is open or closed. The sensor has two parts: a wired sensor unit and a separate magnet. If these are mounted in the wrong orientation, the status reads reversed (showing open when closed and vice versa). Flip the magnet 180 degrees so the opposite pole faces the sensor, or swap the positions of the sensor and magnet.
Mount Sensor on the Top Door Panel
For a sectional garage door, mount the sensor on the top panel (the panel closest to the ceiling when the door is closed). Mount the magnet on the track or wall directly next to the sensor so they align when the door is fully closed. If mounted on a lower panel, the sensor may trigger at the wrong point in the door travel, causing incorrect status readings.
Reduce the Gap Between Sensor and Magnet
The magnetic reed switch has a limited detection range — keep the magnet within 1 inch of the sensor. If the gap is too large, the sensor cannot detect the magnet and defaults to the wrong state. Use the included mounting bracket or add a small shim to bring the magnet closer to the sensor. Test by opening and closing the door and watching the status in the Meross app change.
Test Status Changes in the App
Open the Meross app and watch the garage door status while manually opening and closing the door. The status should change from Closed to Open within 2-3 seconds of door movement. If the status changes but is still reversed (shows Closed when Open), the sensor polarity needs to be swapped — try rotating the magnet 180 degrees or moving it to the opposite side of the sensor.
Update Controller Firmware
In the Meross app, go to your garage door device > Settings (gear icon) > Firmware Update. Install any available updates. Some firmware versions have fixed sensor state detection logic that was previously inverted on certain hardware revisions. After the update, test the door status again.
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.
