Eufy Cam2c Homekit

Mayb someone can help me.

I have a set Homebase 2 with 2 cam 2c and a battery doorbell.

I added Both of the 2c cams in HomeKit. But since 2 weeks they disappear from HomeKit.

I tried everything, reset homebase 2 (I reinstalled the homebase, 2cams) and reinstalled the HomeKit hub (Apple TV 4K). Every time I reset the homebase2 or the HomeKit certification then the cams do show up in HomeKit for some min’s and they disappear after.

All of the devices, Apple TV 4K etc are updated, had a hard reset etc.

Any tips?
