Aqara door and windows sensor's stop working after some time

Hi all,

I am very new to HA and I’ve set it up with a Pi 4 4GB and Conbee2 zigbee dongle.
I use HASSOS and just a small amount of plugins to try out.
I wanted to try a very basic smart home setup with 3 sonoff thermostat’s and 3 aqara sensors.
I’ve setup zigbee2mqtt and I am kinda happy with it.

What currently bothers me are not reacting sensors. Open windows stay “closed”
When I take a look at the aqara devices log, it’s empty and only some thermostat log’s are visible. in Z2M it’s still connected and visible.

But! → When I completely restart Home Assistant, the log’s appear and the last events are shown. Feels more like HA is going to sleep after a while and stops caring about it’s bee’s.

This bug? is ruining my automation. Is there a way to get more information about why it stops working?

The distance of the sensors doesn’t seem to be the the issue. They range from 1-9 meters.
