1wire shows thousands of warnings in the log file

Hi, when I look to the homeassistant.log I can see thousands of entries like this:
“[homeassistant.helpers.entity] Update of sensor.28_176aef422001_temperatur is taking over 10 seconds”
The owserver runs on a Rpi5 with attached 31 sensors DS18B20 in the same network as HA. HA runs on a VM (PVE) with link to this Rpi5
At the same time a NodeRed server is additional connected to the Rpi5 and reads all 31 sensors without any problems or warnings like above. So the network is not the bottleneck-
I have tried to set the precision of the sensors to “temperature9”, “temperature10”, “temperature11” and “temperature12” but no changes .
The temperature is always read from “temperature” and the warnings are still shown in the log.
Does anyone know what could be a cause of?
How can I change the latency of 10 sec (not the polling cycle!) to get rid of the warnings?
