Hi @kirit1193 , Thank you for your feedback, We are aware of this issue and will fix it in the next release.

Please update the plugin to version 1.3.1 and try again

Hi @Hanh94, looks like the color control works now, however, the brightness control doesn't work or is missing.

Changing the color automatically sets the brightness to 49% and there is no way to change that from the HomeKit setup. If I set brightness from the Tuya app and change the color in HomeKit it auto-sets brightness back to 49%.

Hi @kirit1193 , Do we know what's causing it and will we try to fix it in the next release.

There doesn't seem to be a brightness parameter, just a Hue / Saturation / Value parameter being sent to the API:

Perhaps if the brightness value is sent as well. This also explains why there is no brightness control for the 'dd' LED strip.

Does that help?

Looks like this is closed in 1.4.0 with a brightness control. Cheers!
