Hi!
I just installed Shelly 2.5 to my roller shutter. To be excact it's not a roller but pergola roof blinds like this:

There is a Somfy motor. I don't know which model, because it's hidden in the frame. It came with a remote to control it.
Wiring from the motor has 4 wires:
Grey - Phase
Blue - Neutral
Black - Direction 1
Brown - Direction 2
I wired Shelly 2.5 outputs to Direction 1 and 2 and left the Grey (phase) connected around Shelly so that my remote workes.
Probably due that 4 wire design I cannot do the calibration, because power to the motor is taking power from the phase wire and there is no power consumtion the direction wires.
I still want to have position control, so my question is how can I achieve this?
Is it possible to measure opening and closing time and just calculate position from there? Movement is linear and same on open and close.
Other option is to somehow measure the phase wire power but i dont have an idea how to feed this information to shelly2.5.
Somehow my Somfy Nina remote knows the position and it works pretty well. Here is manual, but did not find any calibration stuff from there. https://service.somfy.com/downloads/be_v…lnina_io_v3.pdf
