I agree! I’ve gone looking for this option a few times and always been surprised it is missing.
Also I think adding this option would eliminate (or at least reduce the need for a fix to) this WTH issue. I also rely on device_tracker.see
because there’s no other way to make a custom device tracker out of other state info. But then you have to wait for that state to change after restart in order to trigger your automation and recreate your device tracker. Having a template tracker fixes that since the template can be auto calculated on startup and on entity change.
