If I have a listen state like:
self.listen_state(self.sensorChange, "device_tracker.frank_samsung")
Should I ever expect to see old and new wit the same value in sensorChange? I am seeing it but I’m trying to understand why.
Should I just add if (old==new): return ?
even if old == new there can be something changed.
an entity also has attributes, and with a change there the listen_state is also triggered.
so yeah if you dont want anything to happen, then add a check in the first line from the callback.
Or … just add the values you are looking for on the listen_state line … old=“xxx”, new=“yyy”
