ESP rgbww light goes out of sync

[nicolasbisi]

The problem

I have 2 lights that are being seen by Home Assistant, and I use a helper to control them both at the same time. I notice that my lights are getting out of sync, or losing their limits after a while. One way to easily force it to happen is to enable an effect (always used Random) Before the effect is used, when I move the slider to the warmest colour, we can see that all the values match.

I then turn the random effect on, wait a while, turn it off and set it to the warmest colour again.

Setting the light individually makes no difference. The only way to fix this problem and get them back in sync is to power the off and back on. The same happens with the coldest colour. They don't match after using an effect.

Start by upgrading ESPHome to the latest version. You need to reinstall the ESPHome add-on from the official repo to upgrade to the current version. https://github.com/esphome/home-assistant-addon

I see in the second pic both bulbs are set to 499 mired and seem to have a similar cold/warm ratio, but maybe the brightness of the right one is 1/2 the left one. What would happen next in the second pic if you changed the brightness slider of your helper? If you look at the individual lights in Home Assistant, do they both match the helper?

@bkaufx Thanks for the reply and the link, I didn't know there was another repo. I have updated everything and I'm now running on ESPHome 2022.9.4 I retested everything. I made sure that they were in sync after the update and left "Random" run for a while. I then started moving the sliders (Colour temperature and Brightness), and I'm still seeing it. I moved the light individually to the limits, and they still show different values. On home assistant, it seems that everything is in sync. Doesn't matter where the slider of the group is, the other ones follow, but the log on esphome shows the difference. Visually, the lights are very close, but it's noticeable.
