    Hello guys,

    I have a Shelly Qubino Wave Shutter connected inside a wall switch (with up/down push buttons) controlling my window roller blind. The motor in the roller blind is Somfy Maestria WT and needs to be calibrated because it manages the start/stop positions itself, independent of the calibration in the Shelly relay. The problem is that according to Somfy manual, I would need to be able to hold (regular switch) up/down push buttons for about 3 seconds. It seems impossible now with the Shelly relay, as it "overrides" the push buttons with its own logic.

    Please, is there some option/exploit on how could I proceed with the motor calibration procedure without rewiring the wall switch (I have actually 6 such setups)? I have the Shelly relay added in ZWave JS UI and Home Assistant, but I was not able to figure out something there.

    Thank you for any idea. :)
