Home Assistant Automation

Automate smart home devices and create intelligent automation workflows.

Core Capabilities

Device Control

device_commands: lights: - turn_on: entity_id: light.living_room brightness_pct: 80 color_temp: 350 - turn_off: entity_id: light.all_lights

climate: - set_temperature: entity_id: climate.main_thermostat temperature: 72 hvac_mode: heat

media: - media_play_pause: entity_id: media_player.living_room_tv - volume_set: entity_id: media_player.sonos volume_level: 0.5

Automation Templates

automations: morning_routine: trigger: - platform: time at: "06:30:00" - platform: state entity_id: binary_sensor.alarm to: "off" condition: - condition: state entity_id: person.owner state: "home" action: - service: light.turn_on target: entity_id: light.bedroom data: brightness_pct: 30 transition: 300 - service: climate.set_temperature data: temperature: 72 - delay: "00:05:00" - service: media_player.play_media data: media_content_type: music media_content_id: "news_briefing"

away_mode: trigger: platform: state entity_id: group.family to: "not_home" for: "00:10:00" action: - service: climate.set_preset_mode data: preset_mode: away - service: light.turn_off target: entity_id: all - service: lock.lock target: entity_id: lock.front_door

Scenes

scenes: movie_night: entities: light.living_room: state: on brightness: 20 color_temp: 500 light.tv_backlight: state: on rgb_color: [0, 0, 255] media_player.soundbar: state: on source: "TV" cover.blinds: state: closed

Voice Commands

voice_intents:

• intent: "Turn on the lights" action: light.turn_on entity: light.all_lights

• intent: "Set temperature to {temp}" action: climate.set_temperature entity: climate.thermostat data: temperature: "{{ temp }}"

• intent: "I'm leaving" action: script.away_mode

Integration Examples

Energy Monitoring

energy_dashboard: sensors: - sensor.electricity_usage - sensor.solar_production - sensor.battery_level automations: - name: "Off-peak charging" trigger: platform: time at: "00:00:00" action: service: switch.turn_on entity_id: switch.ev_charger

Security System

security: motion_detection: trigger: platform: state entity_id: binary_sensor.motion_front to: "on" condition: - condition: state entity_id: alarm_control_panel.home state: armed_away action: - service: camera.snapshot entity_id: camera.front_door - service: notify.mobile_app data: message: "Motion detected at front door" data: image: "/local/snapshots/front_door.jpg"

Best Practices

• Entity Naming: Use consistent naming conventions

• Groups: Organize devices logically

• Conditions: Always add appropriate conditions

• Notifications: Don't over-notify

• Testing: Test automations thoroughly

• Backup: Regular configuration backups
