Problem Description

Your Aqara curtain motor fails to complete the calibration process where it learns the open and closed positions of your curtain track.

Symptoms

  • Motor stops before reaching track end
  • Calibration completes but positions are wrong
  • App shows calibration error message
  • Motor reverses direction during calibration
  • Open and close limits are swapped
  • Motor makes grinding noise during calibration

Recognize these? Here's what usually causes it.

Common Causes

  • Physical obstruction on curtain track
  • Motor installed in wrong orientation
  • Track has too much friction or resistance
  • Curtain fabric caught in motor wheels
  • Battery too low for full calibration run
  • Previous calibration data corrupted

Most fixes happen in the first 3 steps.

Warning

Do not force the curtain open or closed during calibration.

Step-by-Step Solution

1

Inspect the Curtain Track

Remove the motor from the track and manually slide the curtain from fully open to fully closed. The curtain should glide smoothly with minimal resistance.

2

Verify Motor Installation

The Aqara curtain motor has an arrow showing which direction it should face. Ensure this matches your track layout.

3

Charge Motor Fully

Calibration requires the motor to travel the full length of the track multiple times. Charge to 100 percent before starting.

4

Reset and Start Calibration

In the Aqara app, go to the curtain motor settings and select Reset Position Limits. Then select Calibrate.

5

Fine-tune Positions

After auto-calibration completes, use the manual adjustment feature to fine-tune positions.

Quick Solutions

Clear all obstructions from track
Verify motor orientation matches track
Clean and lubricate curtain track
Check curtain fabric is not jammed
Fully charge motor before calibrating
Factory reset motor and recalibrate

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.

Pro Tip

Applying silicone-based lubricant to the curtain track before calibration reduces friction.

Real-World Insight

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.

What Usually Goes Wrong
  • Physical obstruction on curtain track
  • Motor installed in wrong orientation
  • Track has too much friction or resistance
  • Curtain fabric caught in motor wheels
  • Battery too low for full calibration run
