Using entity attribute value inside URL tap action?

[douglasmauro]

Goal

I'm trying to pull in a location GPS (lat/long) to put into the URL of the tap_action. I can't seem to find a way of getting it in there and I've found that the UI/Editor seem to clobber each other ... ie I need to clean the UI with blanks else my config/yaml edits won't take.

Some diff examples I've tried... just to give you an idea of what I'm trying to do

variables:
  lat: states['device_tracker.my_device'].attributes.latitude
  lon: states['device_tracker.my_device'].attributes.longitude

Would allow me to use:

  tap_action:
    action: url
    url_path: >
      https://www.google.com/maps/search/?api=1&query=${lat},${lon}



### Source Yaml

```yaml
(see above)
