Using XSense Hub with connected devices be be used in HA Alarm setup

[JuRo1971]

Hi all,
I have a Xsens Hub with different devices connected to the hub. I also use the HA integration. The devices sirine can be executed vi an entity. My ides is now to use these sirenes im my HA alarm setup. In general this is function but the execution of the sirines per device happens in a sequence not in parallel. So I want them ring all at the same time. This is getting very load then :-).
This is my yaml code
alias: Alarm Ton bis zur Abschaltung wiederholen repeat: sequence: - parallel: - device_id: 125e408d803197cc28a7c1dcce23d3aa domain: button entity_id: 6efb893ae899a969eef36c18b6ffd609 type: press - device_id: b10ae617e39eb225b6b01575f9356f18 domain: button entity_id: e32d1ec38025734c4a8fe753b1e42e1d type: press until: - alias: solange, bis Alarm deaktiviert wurde condition: state state: disarmed entity_id: alarm_control_panel.alarmo
Is there something wrong or is this related to the Xsense Hub not possible?
Thanks and greetings
JuRo
