Sorry for my vagueness; This was the last reply i got, sent BEFORE november. It was after i got my dimmers back that they themselves updated to 2.4. I gave up hope after that and didn't bother to look for any news on this (and the 2 wire solution was sort of working anyway). But of course i ...

[forgot the second part of their reply..]

There’s one more method, that none of our agents suggest till now: please try to connect Dimmer 2 with two wires instead of three, that should at least decrease ripple control effect (bulb flicking).

fwiw. This is part of the response i got from Fibaro Tech support: The situation with Dimmer’s sensitivity for ripple control haven’t change, unfortunately. We aleso haven’t develop any suppressors, in fact it is almost impossible in regard of different frequencies of ripple in given country, some ...

One more update on this... I DID see some improvement by connecting the dimmer with 2 wires, instead of the 3 wire connection. Still some flickering, but noticeably better.

Good news for those with offpeak ripple tone issue's. I received this email via Fibaro support. We are currently testing the new OTS module firmware updates as a closed Beta. This issue is noted in the changelog for the Dimmer 2 upgrades. Specifically… “Reduction of stroboscopic-effect for dimers af ...

Hi, for me the problem is not related to the above mentioned 'alarm frame' setting, but to the so called 'ripple control' system used by the electricity distribution network. This system is used to remotely switch on and off all kinds of public services like street lights etc. A good way to check if ...

Just bought two of these dimmers. It all works as advertised, but every now and then my lights start to flicker in a rhythmic pattern. The strange thing is that both dimmers flicker in perfect sync. It looks as if the dimmers cycle through some sort of program. I made a call to the webshop where i ...
