Not sure if this is a “bug” or not. Nothing is really “broken”.
I noticed the sensor entity names are prefixed but the binary_sensor is not.
Sensor:
sensor.wirelesstag_attic_main_humidity
sensor.wirelesstag_attic_main_temperature
Binary Sensor:
binary_sensor.attic_main_low_battery
This hurts my OCD.
Also, it would be nice if these used the entity registration feature now so I could then just change the entity id.
