Hi @Anders_Grauballe, thanks for reporting this. I take it you are using deCONZ. I was able to reproduce the issue and fix it. The issue is fixed in Android version 1.9.2 and iOS version 1.3.3.
After updating Hue Essentials, you will need to reset the motion sensor using the wizard button on the motion sensor screen. Then configure it again using the wizard.
The Android version should be live soon, first in beta. The iOS version will take some more time due to Apple review.
Let me know if this resolves your issue!
