Lights Flickering When Dimming with HS220 and Kasa Smart Dimmable Bulb

2021-12-12 15:02:06

Model: HS220

Hardware Version: V3

Firmware Version:

Hi all,

I have the HS220 installed in 5 rooms with the Kasa dimmable smart bulbs. In 3 out of the 5 rooms the lights flicker when dimming from 100% all the way down to zero. I've checked the wiring. Everything is tight and connected correctly. I don't understand why in two rooms the lights dim fine but in the other three they flicker Everytime when dimmed. Thoughts?

Hello@Ibrahimaf3

1. It is Not recommend to use smart switches with smart bulb together as the ways they work may conflict. Please use them separately.

Smart bulb itself is dimmable and could be controlled in the APP, so we usually do not need another smart switch.

2. Smart bulb may cause some trouble when working with a dimmer:Q9: Will Smart Bulbs work with a dimmer?

Here are some additional information that may help:

- HS220 dimming type is TRIAC based, you may use an incandescent bulb or LED that support Triac dimmer.

- And when smart bulb work with an ordinary switch/ lamp, the switch relay should be ON, so the bulb is on Standby mode and could be reactive from APP

I hope this help.
