I’ve now determined that when the HA instance is restarted, there is another set of motion sensors added:
BEFORE
binary_sensor.hue_outdoor_motion_sensor_1_motion
sensor.hue_outdoor_motion_sensor_1_light_level
sensor.hue_outdoor_motion_sensor_1_temperature
AFTER:
binary_sensor.hue_outdoor_motion_sensor_1_motion_2
sensor.hue_outdoor_motion_sensor_1_light_level_2
sensor.hue_outdoor_motion_sensor_1_temperature_2
Why would it add a second instance of the sensor…the first one is no longer receiving event updates.
After another reboot, the _2 set of sensors is no longer available and the 1st set is appearing/disappearing every 5 secs again.
