I've had the Fibaro Dimmer module controlling 4 x MR16 halogen lights in my bathroom for over a year - without problem.
About a month ago 3 of the 4 12V transformers packed up within the space of about 1 week. The 4th transformer that continued to work was one I had replaced a few years ago.
So the dimmer module only had 1 working transformer and MR16 bulb connected this month.
Whilst I was hoovering the hallway I kept smelling hot plastic as i moved around. After a lot of sniffing I unscrewed my light switch to discover the Fibaro had melted the corner of its casing and could see a spark/arching from within the unit.
In the corner next to the 'L' connection block terminal I can see inside the unit where it looks like a component casing has popped/cracked too.
I immediately turned off the mains power and removed the unit from the light switch. I'm just glad I noticed it during the afternoon and it wasn't sat there cooking through the night!
I have more of the same Dimmer modules installed and so far have not experienced the same problem, but they were bought around the same time so maybe from the same batch.
Photo attached of the damage.
