    Hi, first of all welcome to everyone :)
    I found myself here because I have a problem, but I hope to be here more often. Not just with questions :D

    To the point. I have an SH+ module from LCNa in the switchgear, both of its outputs are lighting circuits. Up to the point where I was using classic incandescent bulbs everything was ok.
    Now, however, after replacing them all, with LEDs, problems have arisen.
    The first was their flickering, but this was eliminated by disabling the filtering of the outputs.
    Now the problem is that the LED bulbs, despite the outputs being switched off, gently glow.
    This problem disappears when I add one classic bulb to the chandelier. However, this solution is not appropriate in the long term.

    So here the question arises, how to remove this effect occurring with triac outputs. Add additional resistance? How and where? Select it according to?

    Please help.

    Thank you.

    Meaning? A colleague is probably thinking of a classic installation, however, here I think the problem lies elsewhere ;)
    Unless I have misunderstood something.

    Yes, the gentleman from LCN suggested 18 C2GH/C2GR modules (for the whole system), a total cost of over £1,600. Two years down the line, it's hard for my woman to accept another expense. So I would prefer to sort this out quickly, fairly cheaply and stress-free ;)

    Well that means the solution is there. The best thing to do would be to buy 1 copy and give the electrodes the PCB of this module to recognize. From the price of the case, connectors and manufacturer's margin I conclude that there is something amazingly simple inside.

    Here I think is a 1999 version of this module [I infer from the sticker on the capacitor 11/99 source: Link ].

    For happiness you need per channel: 1 film capacitor ?330nF?/ for min. 275V + resistor [which should be decoded, a rectifying diode and an LED?
    In 5£ you can sew a suitable spider.... but it would be better for an electronics engineer to analyse it, because personally, despite its simplicity, I do not understand how it works. :)

    Ps: It seems to me that a similar solution is the Bypass from Fibaro. Cost 30pln/brut/piece. Also expensive... but for a test, probably ok.

    Ps2: It seems to me that the simplest possible so called "transformerless" power supply should be used here [as an artificial load].

    Ps3: I think you can connect in parallel to the actual LED load one of the many 230V LED lights available on alledrogo for about 3,5pln. When you test it let us know how it worked out.
