OH3 Color light bulb and Google Assistant

Hi There,

i have installed two Shelly Bulb duo. I want to expose them to Google Assistant but i dont get it to work.
I configured a new item group with the items described in documentation:

First of all the OH GUI did not suggest a Google tag named “lightPower”. So i used just the Light tag.

In Google there is only a light bulb with white spectrum visible but no color configuration.

I have also an internal group “all_lights” which is not exposed to google. To realize this i created two items for the shelly bulb.
But these items are not synchronized:

I think this is really complicated for just a color bulb…

I dont get it… Any help is very apreciated!


Anyone an idea?

There has been an update release so that also a separate Color item can be configured: Google Assistant | openHAB

Thus, I would suggest to replace the lightColorTemperature with lightColor.

The power item needs to have the lightPower metadata set.
As this might not be selectable yet with the UI, you have to manually assign it.

Only the group item should have the light metadata assigned.
