Flickering with 4 Philips LEDs

    Hi All,

    I have a Dimmer2 connected to a ceiling light with 4 Philips 4W 2700K 35mA (9290002147) , I guess the bulbs are connected in parallel with each other.

    Firmware is 20221027-104444/v1.12.1-ga9117d3

    Switching on/off works perfect.

    Dimming 20 > 100% works perfect.

    Dimming 0 < 20 works bad, the led's start to flicker/flash, while the light is still too bright.

    I'm migrating from older Xanura A10 to newer Shelly devices, in the past dimming went flawless with A10 dimmer.


    Example of LED bulb:

    I noticed other people have also flickering issues, how can I try to resolve/debug this?

    I tried playing with calibration and anti-flicker-debounce but with no satisfying result.

    Not all dimmable lamps are compatible with the Shelly dimmer 2, or produce unsatisfactory results. Unfortunately, your lamp is probably one of them. However, we have a list where at least some positive feedbacks are to different illuminants:

    Hi there, do you have the Dimmer2 with or without Neutral?

    Dimmer2 needs at least 10w when without N, and also, at least in my case, when without N flickering is an issue (even when using with a Bypass).

    What i did (maybe it will work in your case) is the following:

    My living room ceiling light was with double sw on the wall, so that the 5 lamp light to have 1 sw for the 3 lamps and another for the other 2. I replaced the lamps with Phillips 4watt dimmable candle lamps, but, i had bridged the N on the ceiling with one of the lines going down to the double sw on the wall. Therefore now i have N to connect the Dimmer2. I placed a normal double button sw and everything is working fine.

    Have in mind that from my experience, everything works better if you have N in the wall switch somehow and if you use dimmable lamps DO NOT use 1L.
