I have a 2-gang Quinetic switch in the lounge. One side is for the
ceiling light, the other for the wall lights.

One evening about 6 months ago - and 3 months after it was fitted - the
ceiling light side wouldn't work, but the wall light side was ok. The
next morning both sides worked without problem. Last night about 9 pm
the ceiling light again wouldn't come on, but the wall lights were fine.
This morning everything was back to normal again.

I assume there is a very intermittent interfering signal for the ceiling
light side. If so, it must be very specific as it doesn't affect the
wall lights side at the same time. Anyone else seen this, and does
anyone know exactly what radio system Quinetic switches use?
