Aquara temperatur sensor sends data in irregular intervals to ConBee 2 integration

I have paired two aquara temperature sensors with my hass using the ConBee II USB stick. Both devices were found and paired using the ConBee 2 integration but for some reason the interval the sensors send data is very variable (varies between a few minutes to more than 5 hours). Does someone know what the issue could be? Humidity data seems to be updated much more frequently than temperature. Is there any way to debug this? I can’t see any activity of the sensors in the logs.
