I have this entry in my configuration.yaml:
- platform: generic
name: Fha
still_image_url: https://maps.googleapis.com/maps/api/staticmap?center={{ states.device_tracker.fha_note3.attributes.latitude }},{{ states.device_tracker.fha_note3.attributes.longitude }}&zoom=13&size=500x500&maptype=roadmap&markers=color:blue%7Clabel:P%7C{{ states.device_tracker.fha_note3.attributes.latitude }},{{ states.device_tracker.fha_note3.attributes.longitude }}&key=xxxxxxxxxxxxxxxxxxxxxxx
limit_refetch_to_url_change: true
How to have a bigger zoom to see better the position in the map? Here it is a value of 13. Which are the values available?
