Hue motion sensor missing

Since latest update my Philips hue are acting weird
Several motion sensors are missing and also I couldnt control my lights

After deleting an adding my 2 bridges back i can control my lights again but the motion sensors are still missing?

Anyone else having this problem or has a possible solution?

Yup I have the same thing. Some show and some don’t and I have no idea why.
I use the temperature readings in calculations and now suddenly get errors in the calculations as the sensors are not available anymore???

Exactly. The latest update resolved it for me

Funny thing! When updated to 2021.4.3, I have the same issue (again). None of my Hue motion sensors are found, and (off topic) all my Zwave devices are gone…
