Shelly Dimmer 2 not dimming on momentary switch.

    Iv just set up a Dimmer 2 and everything is working fine EXCEPT the physical switch on the wall.

    I can turn on/off and dimm via the app and google home.

    I can turn it on and off via the wall switch but I can not dimm.

    The wall switch is a high quality momentary switch connected to SW1

    The "Button Type" is set to "One button mode"

    Anyone else having the same problem?

    I understand you have try to push and maintain for a very short time, and then push again for a longer time until it should began to dim or lit up ? I have the feeling I sometimes have to turn on the light, then click again and keep it just half a second so it doesn't turn off, and only on the second long press the lights are changing their brightness. I have the feeling that the action is not rock-solid, and most of the time it's fine, but sometimes it's capricious.
