Additional context

[spacegaier]

Issue seems to come from here:

Hass-Custom-Alarm/custom_components/bwalarm/alarm_control_panel.py

Line 77 in 9e776bb

from homeassistant.util.ruamel_yaml import JSON_TYPE

The ruamel part has been removed from HA (home-assistant/core#55672), so the import should now be:

from homeassistant.util.yaml.loader import JSON_TYPE

Or could be replaced by a Union if you don't want to rely on HA internals, see https://discord.com/channels/330944238910963714/427516175237382144/893754774149804123
