Hello, Upon further investigation, it turned out that it wasn't the firmware itself that was causing the issue. It was a subsequent layer of adaptive lighting I had overlayed onto it that was masking the symptoms on the version 10. I have confirmed the issue remains on 1.0.8, 1.0.9, and 1.0.10 versions but it has nothing to do with the Kasa devices themselves. The downstream issues are unsupported, we're testing the calling of effects on KL430 from Home Assistant and they were getting hung up; I've now confirmed the issue is with the code in HA not Kasa firmware. Thank you for telling me the updated version of firmware for both versions. Now that you've said that, I recall somebody telling me that in the past.
