HS220 flicker once when turning on

Model: HS220
Hardware Version:
Firmware Version:

I just set up a HS220 today and everything else works fine except for one problem, my default brightness is always 100%, and when I turn on the light, the brightness will flicker like 0%->100%->75%->100%, then it is stable. The light is a LED light, adjustment of brightness just works fine after turning on. I tried to change the fade on speed but that didn't help, any idea what the problem it might be? Any suggestion is appreciated.

What type of dimmable bulb are you using?

@Carl assuming that it is not the bulb, what else would you consider?

Could be the wiring,  It could be electircal noise such as from a motor on a ceiling fan.  Could be a defect.  But usually its the bulb.  There are several types of dimming bulbs and the HS220 is only compatible with  Incandescent/Halogen (forward phase control), based on TRIAC.

@Carl neutral wire nut was loose. I taped it and it does not flicker anymore.

@Carl is there another switch made by TP-Link that is compatible with LED bulbs and is a smart dimming switch?  It's so harder to find incandescent/ halogen nowadays with everything going LED.  Why would they ever make a switch now that doesn't work well with LEDs?

Hi Jack.  Actually TP-Link Dimmable switches do support LEDs.  It supports LED lights based on TRIAC and forward-phase-control, But does not support lights based on PWM (pulse width modulation) and ELV (electronic low voltage) dimming.  So as long as your bulbs are TRIAC or Foward-Phase-Control you should have no issue with the bulb working.

@Carl how can I see if my bulbs are TRIAC?

It should be on the packing or on the bulbs maufacture's website.
