Is it possible to set an alarm on a phone (not a notification) by any means that is of critical importance like fire, smoke, intrusion, water leak, etc that only stops when acknowledged?
I’ve tried https://companion.home-assistant.io/docs/notifications/critical-notifications with high alerts and played with importance https://companion.home-assistant.io/docs/notifications/notifications-basic/#notification-channel-importance but it’s still just notification,
