I have created a light device, it gets all the data correctly in the callback hue, brightness, power....

How ever when Google Home changes the hue, I receive the value in the callback, then then I do a update and report... the brightness on Google Home will jump to 100% from where ever it was, and the hue will be shown on the slider for a few seconds and then revert back to what looks like a default color.

Once you leave the device and come back to it, it also looses the hue value on the selector...

Anyone get this to work successfully?

Are you using the default led_light example or is this with your own project? Have you checked the serial terminal logs to see if there's any discrepancy?

I have found a couple things.

I was not implementing Saturation and I think google did not like that so added that...

Also for some reason, when you pick a new hue from the wheel in google home, it cranks up the brightness to almost 100% at times, I understand why due to HSV values that define a color, but would be nice if they left V out of the picture so your whole string of nicely dim leds don't suddenly go full bright!

With some more playing around Alexa however does not adjust brightness when you pick a new color.

So with some code, I got around the google issue and I only allow brightness changes when the data received only includes brightness, no hue or sat data... voila!
