I have that buttons on my roller shutters. There's a button to down and another to up. The two buttons have a Stop position so if i press the down button the up button goes mechanical (not a press button) to the stop position and the shutter goes all down or stops if i press the stop button pn the down button. On the Shelly 2.5 if i press the down button the shutter goes down but if i press the stop or the up button the shutter goes down again. It's possible to mantain the original effect?
