Motion sensor no longer operates light

I put a Hue motion sensor in my hallway & it started out working great. Then over time - 2 to 3 weeks - it began to be unreliable. It would work occasionally, but it wouldn’t work on an increasing basis. Finally, it quit working completely.

I’m using a Philips Hue light bulb in a ceiling light that is controlled by 2 switches. I’ve changed the light bulb & the motion sensor - both of which worked in other locations in my house - & the motion sensors wouldn’t turn on the light bulbs.

I have no idea what is wrong. Any help?

Look at your logs for associated errors.

Also look at the traces for your motion automation.
