Hello,
at first a disclaimer. The two Dimmers in question are not related to my other question here (posted without getting a replay since April).
Two of my Dimmers 2 have burned out about two months ago. The Dimmers had been operational without issue for at least 3 weeks, although the house was still unoccupied pending further renovation work. They have been used for demostration purposes and short visits in the evening.
The whole electric installation of the house was overhauled by a qualified electrician who has also installed all of our Fibaro modules (over 40 all together). One day he switched off the FI-Schutzschalter (i do not know the proper translation, so i just call it "Fuse") for the entire floor as he did some other work there. Both LED-installations connected to the Dimmers had been on at the time (Dimming level unknown). When he switched the fuse back on, both LED installations went bright again, but a few minutes later they couldnt be switched off, via the wall switch. He noticed the smell of burned plastic and disabled the fuse again. Then he discovered this:

Both Dimmer modules look like this now.
One of the Dimmer modules was connected to three of these ->

(combined load 33 watts)The other Dimmer was connected to eight of these ->

(combined load 48 watts)The shop (Intuitech, claiming to be the first-level Fibaro support in Germany) is claiming that we are at fault and they can not compensate the burnt out modules (they claim to have sent them to Fibaro, who confirmed that we are at fault).
I do not understand what we have done wrong. The Dimmer 2 module is supposed to support a load of 250 watts and we had the installation done by a professional electrician.
Frankly i am concerned now for safety reasons. The scenario that has happened could is basically the same as a power outage, meaning it could potentially happen again anytime. When the power went back on the lights have been on, so there was power on a melted module beneath a wall switch. I do not know if this could have caused a fire or something. We do have 10 other Dimmer 2 modules in the house and are seriously considering getting rid of them...
