Fading bug in the Software? 1.8.5

  • Hi !

    I got a shelly dimmer 2 days ago and installed it. It works well so far. However, there is one little thing that seems like a software bug to me:

    I have my shelly dimmer 2 connected like in fig 2, "no neutral wiring". I'm using 1.8.5, I upgraded immediately when I installed the dimmer so I don't know if the issue also happenes with older firmwares. I think 1.7.1 or so was installed out of the box. I don't remember exactly anymore.

    I have 50 Hz, 230 V. There a 100 W old bulbs connected and I calibrated with leading edge.

    Now the issue:

    When I hit the switch for a short time, it fades the light on to the brigthness it was on the last time I turend it off. If I hit it again for a short time it fades back to off. This is fine.

    However, if the switch is in off and I hit the switch longed, it starts dimming the light towards bright. When I release the button it stops at the current brightness. If now, I hit the buttne again for ashort time to turn the light off, it switches the light off immediately. It skips the fading. I can reproduces this 100 % of the time.

    Is this the right place to report this? If not, where should I put this instead?

    In case this behaviour is intended for some reason, I'ld like to hear the reasoning behind it.

    Thank you very much :)

    If I remember right, short press is always for toggle.

    A new longpress will dim down.

    A ticket to allterco is the right place. (link in lexikon;))

    Have a nice Sunday.

  • Yes short press is toggle between on and off, but that happens with the transition time defined in the settings always, except when the dimmer is in off, then you turn it on by a long press (dimming) and afterwards just do a short press. Then there is no smooth transition to off. Instead it immediately turns off.

    If you turn it on with a short button press, there is a smooth transition to the last brightness. If you then turn it off with a short button press, there is smooth transition to off.

    I think it's wired that the smoothness happening when turing the light off depends on wether you turned it on with a short or a long button press before.

  • FYI: The ticket got a response with first of all I should make a video and send the settings of the device. I sent both.

    Then I got the answer that it's wrong to turn off the dimmer with a short button press and you have to use a long button press in order to dim to 0 % to turn it off. That's kind of odd because that basically means there is a state in which a user could do a short press of a button and that's "wrong". That's super counterintuitive. Furthermore, I set my minimum brightness to 20 %, so I can't even dim to 0 % with a long button press.

    I still think it's a software bug but the service person who answered my ticket didn't really understand the issue and just answered something. :/
