Model: ES20M  
Hardware Version: V1
Firmware Version: 1.0.1.0

I installed an ES20M and it causing flickering in my LED lights when set between roughly 50-85%. I swapped out for a KS225 and it does not flicker in this range but I lose the motion sensing capability. I also tried 2 different ES20Ms that seemed to have the exact same issue so it doesn't appear to be a defect. My LEDs are fairly new NDR recessed lights marked as dimming compatible.

 

I replaced with a motion dimmer of a different brand and it had the same issue until I tweaked a setting it had to change the "dimming control timing". Do Kasa switches having anything like this? I only see an option to decrease the minimum brightness which doesn't help in this case as the flickering happens in the mid-range. Or would upgrading to the version 1.8 hardware help? I see a v1 and v1.8 listed on the product page. Mine appears to be the v1.

 

Edited: corrected typo of "KS225M" instead of "KS225".

Hey  @ewolff,

I will need to talk with my team to see what this feature could be referencing before troubleshooting a solution.

 

To get a better clue - What brand were the dimmers that had the feature? What were the settings available?

 

Do you have an example of the lights that you are controlling? This way we can directly compare the specifications of the fixture and lights, such as compatible dimming types and apparently timings..

The feature was on the Leviton D2MSD smart motion dimmer. The setting was under "Bulb Compatibility" -> "Control Timing". Options were "Normal", "Medium" and "Extended". Switching from Normal -> Medium fixed my issue.

 

The lights being controlled were 6x NDR recessed LEDs marked as dimming compatible. I believe this is the specific model: RZR-CCT27-611

 

Thanks,

Ethan

Hey  @ewolff,

Thanks for all the additional information. One last thing: you mentioned that you tried a KS225M, can you double check the model of the device? We do not have a KS225M, but I assume you meant simply a KS225 or other Dimmer?

 

I have reached out to our teams for more information and will get back to you when I get a response. However, going through the documents, I have a feeling that this may have to do with the dimming type of the lights, as I cannot actually verify that the dimming type mentioned on their site aligns with the compatible dimming types of our dimmers. The Control Timing feature is also something that our team has not heard of before, so we are currently looking into its function.

Yes, sorry I meant the KS225. The KS225 did NOT have the issue, but the ES20M did have the issue. There seems to be some subtle difference in their dimming characteristic.
