I mounted today my Smart Lock U200 Lite. All good, but I cannot calibrating directly. I tried to calibrate with door closed, of course. But, seeing that it gives an error, I tried also with open door. The same situation. First lock and unlock is ok, but the secont - error.
Can you do a manual calibration?
What firmware are you running?
I tried only manual calibration (directly), with long press set button. I did not added the Lock in Aqara Home yet. So, I don’t know the firmware.
And what happens if you start the automatic calibration?
Hello, my practice shows that during the first installation, you need to perform automatic calibration (with the door closed) and then perform manual calibration.
Install the Aqara app, it’s easier to install the door lock.
