Per @guzzijones's recommendation logic needed to be added to cycle the sensor if the token is expired based of the TTL of the token

As per comments in #4928 I'd like to see why the existing code to refresh the token isn't working.
There is logic to refresh the token as long as we access via the sensor_service, which in turn calls the get_api_key in the datastore.py (which is where the refresh logic is).
In the example of where this fails, are we trying to access the api client without going through the sensor_service methods? If so, why? Do we need to add more methods to sensor_service instead, so that you can benefit from the refresh key code in there.
OR have we got a bug in that refresh code.

The fact that we restart the service to create a new token is not ideal. yes we 'refresh' the token, but the way we do it isn't the cleanest.
