@carnosine Could you perhaps elaborate on the troubles that you had encountered with this scenario?

If you might like, feel free to enable the script’s logging for more info. (If you haven’t yet installed the Home Assistant Log Viewer add-on , I’d recommend installing that. That should add a “Log Viewer” item to your sidebar within Home Assistant.)
