Hi,
I am trying to show the position of my car on google maps. This works ok, but when the car moves, the gps coordinates are not available (LAT, LON=“unknown”) and an invalid map is displayed. How can I prevent displaying invalid GPS coordinates? Any ideas?
type: custom:config-template-card
variables:
LAT: states['device_tracker.golf_position'].attributes.latitude
LON: states['device_tracker.golf_position'].attributes.longitude
entities:
- device_tracker.golf_position
card:
title: Golf
type: iframe
url: >-
${"http://maps.google.com/maps?&z=18&mrt=yp&t=k&q="+LAT+","+LON+"&output=embed"}
aspect_ratio: 80%
