Dual R3 Motor Calibration issues

1

I have a window blind motor that I set up with a Dual R3. When I first set up the device in the app, it works fine when pressing up/down/stop. It gives me the warning to calibrate the motor. When I do this, it will turn the device for 2-3 mins and then show as calibrated. However, after calibration… Nothing works. Not open/close/stop. When delete the device and set it up again without calibration… It works. Any way to just have the app use “seconds” to open or close without calibration?

Are you saying that after calibration, tapping to open/close/stop the device will not respond?

Yes, that is correct.

Could you please record a video and send it to us in the Feedback ticket?
We’ll do a check on it.

I have installed a Dual R3 to drive my 1/3 HP garage door motor. It works fine using the app to open and close with a 300W load limit to stop it at either fully opened or closed.
The app reminds me each time I open it to calibrate the motor. As the motor has no limit switch installed, when I first tried to use the calibrate feature it ran in one direction and stopped with the motor still trying to run for a few seconds before I chickened out and manually stopped it.
I would like to understand how the calibration works and if it does require limit stops on the motor, how can I prevent the warning to calibrate the motor each time I open the app showing.

@Erin I have the same problem over here.

This was the old switch:

I removed it and connected it like this to the Dual R3:

Here it is doing the calibration automatically:

It stopped there, this was the 3rd time calibrating.
1st and 2nd time calibrating it went well and went back to the starting position.
Problem is: Every time after calibration it will not work in the app.

I tried 3 way rocker switch and 2 way switch, but stay irresponsive.
I should be on the last firmware according to the app.

Is there any solution?

Thanks in advance!
