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? Also how can I prevent the warning to calibrate the motor each time I open the app?
We will add the manual calibration feature in the next OTA, please wait for the update.
Hi @Daniel_Zhan
I have the exact same issues, except that my garage door needs a 360W load limit to work properly (lower value will stop it before being fully closed/opened).

Do you know if the 360W limit can be raised, as it seems to be the maximum supported value in the app. Why not allowing any value here finally ?
-
Do you have an ETA for the manual calibration feature and do you have more details for this feature ? how it is supposed to work ?
Thanks a lot for anwering me.

The DUALR3 will monitor the motor current while calibration. The current will decrease dramatically when the motor approaches the limit end, when the current is decreased to 1/2, we consider that the motor reaches the end. The current calibration solution requires the limit switch.
The ETA of the manual calibration feature is Jan, we are working on this now.
