No devices were found in your openHAB account

Hi,
I try to add openHAB to Google Home. There is the error:
No devices were found in your openHAB account.
In openHAB I have device and I also add metadata like the picture. Any suggestion?

Thank you and regards.

Sorry anyone that can help me, please?
Thank you

Solved.
I use the items file configuration like this and works:

Color pippo "pippo" { channel="deconz:colortemperaturelight:00212E02482D:7cb03eaa00a95bf503:brightness", ga="Light" [ colorTemperatureRange="2700,6999" ]}
