  • Hi, I am connecting shelly 1 to 3-ways connection. Although I have neutral wire, lights are flickering. What can cause it?

  • Shelly 1 has absolutely no dimming function. Without neutral, it will not work (as you mentioned). Thus, what could be the reason for flickering? Some hints and questions:

    Is the lamp flickering without Shelly 1?

    What type of bulb is it? Incandescent, halogen, LED, neon tube?

    Double check all electrical connections!

    Shorten the wire ends in order to mask non-isolated parts!

    Don’t use yellow/green wires for live connections!

    Why is one lever of the Wago clamp not aligned with the others?

    Engage an electrician if you should be not skilled enough!

  • There are 4x4W Led lights. They do not flicker without Shelly.

    It is just test. In production there will be correct wires with correct length.

    I had join 4 shelly at home (two of them are in 3-way connection). That is wierd behaviour, but I do not need electrician, my skills are good, but flickering is something what I did not experience (just with this case). I just need some advice to learn something new;).

  • Ok. Due to the fact, there is a simple relay contact in the Shelly 1 between terminals I and O, cause for flickering is not numerous. Do you hear clicking of the relay? Also in circumstances it should not click? Another issue: The terminals of the Shelly 1 could have been broken due to tightening the screws too hard. But this could be identified by stressing the wires while the gadget is powered on.
