[APP][Pro] Philips Hue Zigbee (Without the bridge)

Trying my luck again.
Unfortunately, a few months ago, my Philips outdoor motion sensor went offline. Now when I want to add it back to my Homey i am unable to complete the addition process. After a while of the Device being added screen it ends with this warning: Unable to Connect.
Batteries are not the problem.
Do you have any idea what could be the problem?

Thanks
