Diagnosis
This is a sensor calibration issue. The iSmartGate thinks the 'tilt' angle of the door when it's down still counts as 'open'. It doesn't know where the true 'closed' position is.
How to Fix It
You need to manually re-teach the sensor the open and closed positions. In the iSmartGate app, go to the main screen for the door having the issue. Tap the three dots or 'Settings' for that door. Look for 'Calibrate Sensor' or 'Sensor Settings'. You'll see instructions to move the door to a specific position. Usually, it's: 1) With the door fully closed, tap 'Set Closed Position'. 2) Then, open the door fully and tap 'Set Open Position'. The app will take readings and should now report accurately.
If That Didn't Work
The tilt sensor might have come loose and is now pointing at a different angle. Check that it's still securely stuck to the top section of your garage door, with the arrow pointing upwards. If it's rotated, the readings will be wrong.
Heads Up
If you have a sectional door that doesn't go completely horizontal when open—like one that curves into the garage ceiling—the sensor might get confused at the top of travel. In the sensor settings, there's often a 'Door Type' option. Try switching it from 'Sectional' to 'Tilt-Up' or vice-versa and recalibrate.
