Home Assistant Skill

Control smart home devices via the Home Assistant REST API.

Setup

Set environment variables:

• HA_URL — Your Home Assistant URL (e.g., http://10.0.0.10:8123)
• HA_TOKEN — Long-lived access token (create in HA → Profile → Long-Lived Access Tokens)

Safety Rules

Always confirm with the user before performing these actions:

• Locks — locking or unlocking any lock
• Alarm panels — arming or disarming
• Garage doors — opening or closing (cover.* with device_class: garage)
• Security automations — disabling automations related to security or safety
• Covers — opening or closing covers that control physical access (gates, barriers)

Never act on security-sensitive devices without explicit user confirmation.

Entity Discovery

List all entities

curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[].entity_id' | sort

List entities by domain

# Switches
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("switch.")) | "\(.entity_id): \(.state)"'

# Lights
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("light.")) | "\(.entity_id): \(.state)"'

# Sensors
curl -s "$HA_URL/api/states" -H "Authorization: Bearer $HA_TOKEN" \
  | jq -r '.[] | select(.entity_id | startswith("sensor.")) | "\(.entity_id): \(.state) \(.attributes.unit_of_measurement // "")"'

Replace the domain prefix (switch., light., sensor., etc.) to discover entities in any domain.

Replace tts.google_en with your TTS entity and media_player.living_room_speaker with the target speaker.

Call Any Service

The general pattern for any HA service:

curl -s -X POST "$HA_URL/api/services/{domain}/{service}" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"entity_id": "domain.entity_name", ...}'

Batch operations

Control multiple entities in one call by passing an array of entity IDs:

# Turn off all living room lights at once
curl -s -X POST "$HA_URL/api/services/light/turn_off" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"entity_id": ["light.living_room", "light.living_room_lamp", "light.living_room_ceiling"]}'

Error Handling

Check API connectivity

curl -s -o /dev/null -w "%{http_code}" "$HA_URL/api/" \
  -H "Authorization: Bearer $HA_TOKEN"
# Expect: 200

Verify entity exists before acting

HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
  "$HA_URL/api/states/light.nonexistent" \
  -H "Authorization: Bearer $HA_TOKEN")
# 200 = exists, 404 = not found

HTTP status codes

Code	Meaning
200	Success
400	Bad request (malformed JSON or invalid service data)
401	Unauthorized (bad or missing token)
404	Entity or endpoint not found
405	Method not allowed (wrong HTTP method)
503	Home Assistant is starting up or unavailable

Response Format

Service calls return an array of state objects for affected entities:

[{"entity_id": "light.living_room", "state": "on", "attributes": {...}, "last_changed": "..."}]

• Successful call with no state change: returns [] (empty array)
• State read (/api/states/...): returns a single state object
• Errors: returns {"message": "..."} with an HTTP error code

Template Evaluation

The /api/template endpoint evaluates Jinja2 templates server-side. Useful for computed queries.

curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "TEMPLATE_STRING"}'

Examples

# Count entities by domain
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ states.light | list | count }} lights"}'

# Get entity state in a template
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ states(\"light.living_room\") }}"}'

# List all entities that are "on"
curl -s -X POST "$HA_URL/api/template" \
  -H "Authorization: Bearer $HA_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"template": "{{ states | selectattr(\"state\", \"eq\", \"on\") | map(attribute=\"entity_id\") | list }}"}'

Available template functions: states(), is_state(), state_attr(), areas(), area_entities(), area_name(), floors(), floor_areas(), labels(), label_entities(), devices(), device_entities(), now(), relative_time().

History & Logbook

Entity state history

# Last 24 hours for a specific entity
curl -s "$HA_URL/api/history/period?filter_entity_id=sensor.temperature" \
  -H "Authorization: Bearer $HA_TOKEN" \
  | jq '.[0] | [.[] | {state: .state, last_changed: .last_changed}]'

# Specific time range (ISO 8601)
curl -s "$HA_URL/api/history/period/2025-01-15T00:00:00Z?end_time=2025-01-15T23:59:59Z&filter_entity_id=sensor.temperature" \

• Test entity IDs with the list command first
• For locks, alarms, and garage doors — always confirm actions with the user
