HomeMatic lose connection to devices after reboot of host system

[rabesocke]

The problem

I'm new to HomeMatic and integrated several thermostats to Home Assistant. But I have the problem that after every reboot of the host system all thermostats are disconnected from the add-on.

Sometimes it works when I delete all devices and reset them in order to connect them again. But sometimes I have to uninstall the add-on completely.

Environment

• Add-on with the issue: HomeMatic CCU
• Add-on release with the issue: 11.0.5
• Last working add-on release (if known): i started with 11.0.4, but there the error already exists
• Operating environment (OS/Supervised): Home Assistant OS 5.9 64-bit /

I switched to the RaspBerry Matic Home Assistant Addon and it works even after restart.
