Home Assistant Automation Guide

Automations in Home Assistant allow you to create smart actions based on triggers like time, motion, or device states. This guide explains how to set up automations using both the UI and YAML configuration.

What Are Automations?

Automations consist of three parts:
1️⃣ Triggers – Events that start the automation (e.g., motion detected, sunset, button press).
2️⃣ Conditions – (Optional) Conditions that must be met (e.g., only run at night).
3️⃣ Actions – The result of the automation (e.g., turn on lights, send a notification).

Creating Automations via UI (Beginner-Friendly)

1. Go to Settings > Automations & Scenes.
2. Click Create Automation and choose:
   • Start with a blueprint (predefined templates)
   • Create from scratch (manual setup)
3. Configure the Trigger, Condition (optional), and Action.
4. Click Save & Enable to activate the automation.

Example: Turn on Lights at Sunset

• Trigger: Sunset
• Condition: None
• Action: Turn on living room lights

Creating Automations via YAML (Advanced Users)

For more flexibility, automations can be written in YAML inside automations.yaml.

Example: Turn on Lights When Motion is Detected

Add the following to automations.yaml:

- alias: 'Turn on lights when motion is detected'
  trigger:
    - platform: state
      entity_id: binary_sensor.motion_sensor
      to: 'on'
  action:
    - service: light.turn_on
      target:
        entity_id: light.living_room

How to Apply Changes:

1-Save the file.

2-Restart Home Assistant to apply the automation.
