Aqara Shutter Switch H2 EU - Failed calibration with two motors

SalvoV · January 31, 2026, 8:52pm

Hi there,

We recently installed Aqara Shutter Switch H2 EU for all our shutters at home. They work like a charm, except for one case.
We have a large terrasse door with shutters that are split into two individual segments, each controlled by an individual motor.
We had a single analog switch that controlled both motors. The Aqara Shutter Switch H2 EU is able to drive both motors, but it fails during calibration. It is not able to detect the travel limits when both motors are connected.

I tried connecting one motor only (tried with both motors) and in that case the calibration works without issues. But then when plugging the second motor, the switch doesn’t detect the limit when actuating the motors together. The shutters open / close correctly but the switch only “stops”/“turns off” only after some timeout (3-5 minutes).

Did anyone encounter a similar issue?

Thanks in advance for any help!

Hi! I just installed the H2 EU myself. Since you are using two motors on one switch, the Smart Calibration likely fails because the switch cannot correctly detect the current drop when the motors stop (the combined load curve confuses the sensor).

However, I noticed in the app that there is a ‘Custom Calibration’ (Lab) option below the Smart Calibration button. Have you tried using that? This should allow you to set the opening/closing times manually, bypassing the automatic current detection.
