Motion sensors disappearing and re-appearing under "States"

Hey, I dont know if this is a bug or an error Ive caused along the way but I see the below philips hue motion sensors almost “blinking” (disappearing and re-appearing) in real time every other second underneath the “States”-tab in the dev-tools.

To clearify, their status is the same “off” at all times, its the entrie entity thats blinking.

I also sporadically get notifications from Alexa on my phone saying that “Your XX Sensor motion is connected to alexa” (XX=one notification for each of the affected sensornames)

  - binary_sensor.balcony_sensor_motion
  - binary_sensor.bathroom_sensor_motion
  - binary_sensor.bedroom_sensor_motion
  - binary_sensor.cave_sensor_motion
  - binary_sensor.corridor_sensor_motion
  - binary_sensor.hallway_sensor_motion
  - binary_sensor.kitchen_sensor_motion

Any ideas on how I troubleshoot this without resetting my configuration?

EDIT: Error messages in my log gave me one result, 8 days old but unsolved thread:
