refine adjustment after automatic calibration

[Haade]

The module perfectly integrated and calibrated with zwaveJS UI, I realize that on all the shutters of different brands really close (physically) at 70% when shelly announces at the end of the calibration half closing.

After timed tests it turns out that the calibration is carried out in half the time because it is calculated in terms of time. But half of the time actually represents approximately 70% closing of the shutter.

Now after automatic calibration how to calibrate the shutter at mid-stroke is it possible if yes can you give me the instructions to refine this adjustment.?

The only way to calibrate the Wave Shutter is trough the parameter 78 and the S button. The motor has to be connected directly to the Shutter and it should not have any extra electronics apart of the limit switches.
Can you let us know the model of motor you're using, or maybe link to the motor user manual, so that we can try to check why this is happening.

calibration with parameter 78 is correct because the time and open and close is 26 secondes and shutter stop to 50% at 13 secondes

but the movement of the shutter is not correct and it is the same for all brands, when the shutter is in the high position and we ask for a descent the slats go down instantly but once at the bottom there is the delay or the slats group together and it takes some time, this time should not be counted during calibration because it is additional time before total closure. Is there a way to do this manually?

The parameters in the print screen is where the shutter saves and then later draws its calibration data in/from. After calibration you can ask the device what its value is and then change it, subtract or add, however much you want, to customize your system. Time should be in centi seconds.

In the real world, there is a "drift" when the shutter relies only on timer calibration. This adjustment will deteriorate in either direction with usage, not time but times of use, It will eventually correct when it hits an end switch but by then the value will be incorrect for your application and you will have to fix it again.

How do you get to the shutter_uptime downtime parameters ?

The Shutter parameters 74 and 75 are present but currently not functioning, the parameters will be fully implemented in the future release of the Firmware.
