Shelly dimmer turn light on and off immediately

  • Hi all,

    I'm pretty new about Shelly and home automation.

    I recently installed a Shelly dimmer following the scheme: fase/neutro to the Shelly, fase from shelly to the light, fase to the switches (3) and then the signal return to the Shelly.

    It happens, sometimes, when I press the switches that light goes on and then off immediately.

    For what I can see there is always a low tension coming back from the switches wires. I guess that could be the issue.

    I also tested the dimmer with a standalone switch outside the house plant and it work as expected.

    So could be the Shelly dimmer is too sensitive? Is there a way to tune this sensitivity?

    Thanks to all

    Domenico

    This is the problem, you have tosolve.

    Something is wrong with the wiring, please check this.

  • Hi, have you solved the issue? I have the same problem which is there is a problem with multiple temporary switches. There is always some oscillations on the switch wire generated by shelly (when this wire is unplug there is no connection to anything) this may be the problem with the length of the wires because when switch wire is short then there is no issue. Any solution to this? Maybe Shelly lacks some filter which can be added by myself?

  • Ok guys, the problem disappeared as soon as I got the internet connection from my isp after software update there is button debounce parameter which probably fixes the problem.
