IoT Alarm Blueprint

A powerful, highly customizable Home Assistant Blueprint for a DIY IoT Alarm System.

Features

Easy Arm/Disarm: Use a simple input_boolean switch to enable or disable your alarm.
Door/Window & Motion Sensors: Automatically filter and select from your existing binary sensors to act as alarm triggers.
Geo-fencing / Away Mode: Optionally select Device Trackers or Persons. The alarm will only trigger if everyone selected is marked as not_home.
Instant Sirens: Trigger multiple sirens, lights, or switches immediately upon an intrusion.
Actionable Mobile Notifications: Get an instant push notification via the Home Assistant mobile app with exactly what triggered the alarm, plus a built-in Silence Alarms button to verify and turn off the sirens directly from your lock screen.
Open Sensor Check & Arming Confirmation: Check for open doors/windows upon arming, with configurable modes: actionable Cancel Arming / Bypass & Arm prompts, warning notifications, or automatic disarming.
Night Mode Schedule: Optionally set a timeframe where the alarm automatically bypasses geo-fencing (allowing you to arm while sleeping inside) and ignores selected sensors (like hallway motion).
