Device Tracking stopped using the Known Devices yaml file and switched to being a built in entity.

This resulted in owntracks reporting dansphone_2 but all the automations were setup for 'dansphone'.
I renamed the known devices file and renamed the entity in HA. This seems to have the tracking and
automations working correctly again.

known_devices.OLD
