Air quality addon not showing data

I installed air quality add-on as per the instructions on the bindings reference page. I am using the location settings for things. The airquality.things is parsed correctly but i don’t see any values. I am using the sitemap as in the documentation here

i checked running the api directly with the key and the location settings and the it is returning the correct values.

In the logs, i don’t see the data getting queried. Do i have to any settings for scheduling the fetching of data?

Thanks… Moving the question to the thread mentioned.
