I was building an automation/blueprint the other day, and it struck me that we have no way to specify 1 entity in a selector for both tracking the location (entering/leaving a zone) AND sending it a notification.
I worked around this by making the selector work with device_tracker entities provided by mobile_app, and then doing some string manipulation magic to get the notify entity for the same device, but this is far from ideal (e.g., when the ids have been changed by the user, my blueprint would break).
In the ideal world, I’d like to add a “preferred” device_tracker and notify entity to a person, so that we can just use a selector for person, and then perform those actions on a person in our blueprints.
