Flashing LEDs when fan and lights off

[Mike Johnson]

I understood that's what's essentially been done, but the switch shown is also the light switch!

And I think that is where the problem is, Ghost voltage from the main switch, a snubber should sort it out, two way by chance?

I have the same unit to control my shower fan, it switches two independent LED GU10's in the shower cubicle without any flickering, but then I did wire it in accordance with the wiring diagram in post 7 between the SL and N into the Manrose unit after the switch.

So the switched feed to your LED's is connected to pin 2 of the Manrose thing, they are less than 15W, and they don't flicker!
So much for my theory!

The timer is wired as per instructions and ligjting load is 4x4.8w LEDs, and to act as a snubber I wired the shower light which is a gu10 as the last lamp on the run. I have also tried two (in case one was duff!) 47uF 100r capacitor across every combo of terminals - I'm baffled.
I'm going to try a 1 way switch at the light switch as I am using a two way but in 1 way config.

I really appreciate all the help and advice - I'm struggling with this one!!

Have you tried the capacitor across one of the LED's?

I have, on the first LED in the run, where I switched them. I'll try one of the others now though. I have just changed the switch to a 1w as opposed yo the 2w that I was using - back soon!

To stop the stray voltage in my kitchen flashing the LED's I had to use snubbers on four of the twelve lights.

The one way switch as opposed to a two way would only make a difference if wired two way.

I have fitted the capacitor across one oc yhe other LEDs and no change and swapped 2w for 1w switch.

Managed to upload screenshot of wiring - sorry for rubbish art skills!!!

Not drawn on sketch is DP switch just before timer (between 1st LED JB and timer on sketch).

Put on an additional snubber and re-draw your sketch.
