Show Google Maps as a card
Using the generic camera platform you can present any image on the internet as a camera. Starting release 0.27 these urls can also be based on a template. This example uses this functionality to point a generic camera at the Google Maps static image API and pass in the location of a device.
It also leverages the limit_refetch_to_url_change option to ensure that we do not make a lot of requests to the Google Maps API.
