core: fritzbox after timeout entities are no longer available

The problem

For some time now, the entities in AVM Fritz!SmartHome are no longer available after a short time in use. A reload of the integration does not help.If you restart the core, the entities are available again and work as usual. Since I missed the exact time since it started, I can not say whether it started since the update of FritzOS to 7.28 or HomeAssistant. A new setup of the integration brought nothing. It works briefly, then again not. I have read through the issues concerning AVM here and the following logs: logs: homeassistant.components.fritz: debug fritzconnection: debug fritzprofiles: debug

I can only find the posted timeout though.

I am running a Fritzbox 7590 with a FritzRepeate 2400, different Fritz!Dect 301, Fritz!DECT 210 and two Fritz!Dect 440.

I don’t know if this helps, just as a little additional information: To help me temporarily, I run a parallel Hombridge with the following plugin https://github.com/SeydX/homebridge-fritz-platform#readme to access the devices in Homekit. Here the problem does not occur.
