Hi there, Ken_1.
Your Nest Aware subscription will cover all devices in a single Home/Structure. If you have multiple Homes, then you will need to have a subscription for each home. It does not encompass all of them. Please let me know if you need further assistance.
It looks like we haven't heard back from the OP so I'm going to go ahead and lock the thread. If you have any further questions or concerns, feel free to create a new thread.
Have a great day,
