Problem with google_traffic_time polling too often

Got those two sensors, and because Google started charging for using the API, I set the “scan_interval to 600”, thinking that this would mean polling every 10min.
But it’s still polling thound times a day, and now my $300 free polling are used up after 3 days. :frowning:

Is my syntax wrong? The # is there, because I deactivated the sensor now.

That should work. Are you sure you restarted HA after adding scan_interval?

Yes. Several times. And the number grew quite fast (checked on Google’s API page)
