Hi Mark,
i have tried to use google home with NHC 1 using myopenhab cloud service. It seems google home requirements are the Lights should have “Lighting” tags (Official Google Assistant Integration for openHAB) to be populated for google home.
Maybe other items should have other tags as well (https://www.openhab.org/docs/ecosystem/google-assistant/).
Please would it be possible to add tags for automatically generated switch (lights) items?
Even writable tags would help a lot.
Tags for NHC items are read only now and it seems this is the reason i can’t see them at google home control.
I have tried to edit Tags using REST API but got readonly error message 
Thanks for any effort regarding this.
Marek
