Tuya lights working for 38 lights, but 7 are offline

I am running OH3 on a rapsberrypi 4. I have 38 tuya lights running over MQTT.
It is working fine. But last week i got 7 new and they stay off line.
The only difference is the 38 are Ledvion RGBCW end the new are Ledvion RGBCCT.
In the app and on the tuya platform they are online and i can controll them.
In openhab and Mqqt-Explorer they are offline
Can somebody help me?
