Per la configurazione con gli Assistant avete letto per bene qui?
E visto gli esempi?
The device name imported in the assistant will be label given to the item, and not the item name; usually you can rename devices in the assistants. (item labels are not mandatory in openHAB, but for the Google Assistant Action they are absolutely necessary)
Note that the most flexible configuration is obtained using .items file: see the examples below.
You will need to add tags manually for items created using PaperUI when Simple Mode item linking is de-activated, or for items created using .items file
