HMIP-SMI55 Disappearance Issue and CCU Restart Solution

Hello everyone, I’m new to the world of smart home technology and I’ve been absolutely thrilled with my recent setup. I’ve installed several HMIP-SMI55 wall motion detectors and they’ve been working perfectly until I decided to restart my CCU. To my dismay, the motion detectors vanished from my system, forcing me to reset them to factory settings and relearn them each time. This has been quite frustrating, especially since I had to adjust my programs every time. I was wondering if anyone else has encountered this issue and if there’s a more permanent solution to prevent this from happening in the future. I’m hoping to find a way to keep my devices stable without constantly reconfiguring them. Any advice or insights would be greatly appreciated! :pray:
