I'm trying to wire up some dimmable LEDs to a Shelly Dimmer 2.
The LED is a 9W dimmable model.
However I seem to have a lot of issues with flickering, particularly at lower dimmer levels.
This is how I've wired it up:
- Power cord active goes to the middle "L" terminal on the Shelly Dimmer 2
- LED dimmer active goes to the right-most "O" terminal on the Shelly Dimmer 2
- Neutral from power cord and LED dimmer goes to a screw terminal, along with a short bridge conductor down to the "N" terminal on the Shelly Dimmer 2.
This works well at 100% (i.e. not dimmed).
I then did a calibration on the Shelly Dimmer 2.
At 100%, there is no flickering. However, even at 50%, there is very noticeable flickering. 30% it's psychedelic.
I then added a Shelly Bypass, wiring it in parallel on the output line:
It no longer flickers at 50%, however, it still flickers at 30%.
Question:
- In my case, I do have a neutral wire. But should I still be using the Shelly Bypass? (It does seem to make things better, but just wanted to confirm it was the correct thing to do).
- Does anybody have any tips on how to reduce the flickering? I do want to be able to use it at say 20% or 30% output, without flickering if possible.
