Extended OpenAI Conversation

This is custom component of Home Assistant.

Derived from OpenAI Conversation with some new features such as call-service.

Additional Features

• Ability to call service of Home Assistant
• Ability to create automation
• Ability to get data from external API or web page
• Ability to retrieve state history of entities
• Option to pass the current user's name to OpenAI via the user message context

How it works

Extended OpenAI Conversation uses OpenAI API's feature of function calling to call service of Home Assistant.

Since OpenAI models already know how to call service of Home Assistant in general, you just have to let model know what devices you have by exposing entities

Installation

1. Install via registering as a custom repository of HACS or by copying extended_openai_conversation folder into <config directory>/custom_components

2. Restart Home Assistant

3. Go to Settings > Devices & Services.

4. In the bottom right corner, select the Add Integration button.

5. Follow the instructions on screen to complete the setup (API Key is required).

   • Generating an API Key
   • Specify "Base Url" if using OpenAI compatible servers like Azure OpenAI (also with APIM), LocalAI, otherwise leave as it is.

6. Go to Settings > Voice Assistants.

7. Click to edit Assistant (named "Home Assistant" by default).

8. Select "Extended OpenAI Conversation" from "Conversation agent" tab.

Configuration

Options

By clicking a button from Edit Assist, Options can be customized.
Options include OpenAI Conversation options and two new options.

• Attach Username: Pass the active user's name (if applicable) to OpenAI via the message payload. Currently, this only applies to conversations through the UI or REST API.

• Maximum Function Calls Per Conversation: limit the number of function calls in a single conversation. (Sometimes function is called over and over again, possibly running into infinite loop)

• Functions: A list of mappings of function spec to function.

  • spec: Function which would be passed to functions of chat API.
  • function: function that will be called.

3. native

3-1. Add automation

Before adding automation, I highly recommend set notification on automation_registered_via_extended_openai_conversation event and create separate "Extended OpenAI Assistant" and "Assistant"

(Automation can be added even if conversation fails because of failure to get response message, not automation)

Create Assistant	Notify on created

Copy and paste below configuration into "Functions"

For English

- spec:
    name: add_automation
    description: Use this function to add an automation in Home Assistant.
    parameters:
      type: object
      properties:
        automation_config:
          type: string
          description: A configuration for automation in a valid yaml format. Next line character should be \n. Use devices from the list.
      required:
      - automation_config
  function:
    type: native
    name: add_automation

For Korean

- spec:
    name: add_automation
    description: Use this function to add an automation in Home Assistant.
    parameters:
      type: object
      properties:
        automation_config:
          type: string
          description: A configuration for automation in a valid yaml format. Next line character should be \\n, not \n. Use devices from the list.
      required:
      - automation_config
  function:
    type: native
    name: add_automation

3-2. Get History

Get state history of entities

- spec:
    name: get_history
    description: Retrieve historical data of specified entities.
    parameters:
      type: object
      properties:
        entity_ids:
          type: array
          items:
            type: string
            description: The entity id to filter.
        start_time:
          type: string
          description: Start of the history period in "%Y-%m-%dT%H:%M:%S%z".
        end_time:
          type: string
          description: End of the history period in "%Y-%m-%dT%H:%M:%S%z".
      required:
      - entity_ids
  function:
    type: composite
    sequence:
      - type: native
        name: get_history
        response_variable: history_result
      - type: template
        value_template: >-
          {% set ns = namespace(result = [], list = []) %}
          {% for item_list in history_result %}
              {% set ns.list = [] %}
              {% for item in item_list %}
                  {% set last_changed = item.last_changed | as_timestamp | timestamp_local if item.last_changed else None %}
                  {% set new_item = dict(item, last_changed=last_changed) %}
                  {% set ns.list = ns.list + [new_item] %}
              {% endfor %}
              {% set ns.result = ns.result + [ns.list] %}
          {% endfor %}
          {{ ns.result }}

4. scrape

4-1. Get current HA version

Scrape version from webpage, "https://www.home-assistant.io"

Unlike scrape, "value_template" is added at root level in which scraped data from sensors are passed.

- spec:
    name: get_ha_version
    description: Use this function to get Home Assistant version
    parameters:
      type: object
      properties:
        dummy:
          type: string
          description: Nothing
  function:
    type: scrape
    resource: https://www.home-assistant.io
    value_template: "version: {{version}}, release_date: {{release_date}}"
    sensor:
      - name: version
        select: ".current-version h1"
        value_template: '{{ value.split(":")[1] }}'
      - name: release_date
        select: ".release-date"
        value_template: '{{ value.lower() }}'

5. rest

5-1. Get friend names

• Sample URL: https://jsonplaceholder.typicode.com/users

- spec:
    name: get_friend_names
    description: Use this function to get friend_names
    parameters:
      type: object
      properties:
        dummy:
          type: string
          description: Nothing.
  function:
    type: rest
    resource: https://jsonplaceholder.typicode.com/users
    value_template: '{{value_json | map(attribute="name") | list }}'

6. composite

6-1. Search Youtube Music

When using ytube_music_player, after ytube_music_player.search service is called, result is stored in attribute of sensor.ytube_music_player_extra entity.

- spec:
    name: search_music
    description: Use this function to search music
    parameters:
      type: object
      properties:
        query:
          type: string
          description: The query
      required:
      - query
  function:
    type: composite
    sequence:
    - type: script
      sequence:
      - service: ytube_music_player.search
        data:
          entity_id: media_player.ytube_music_player
          query: "{{ query }}"
    - type: template
      value_template: >-
        media_content_type,media_content_id,title
        {% for media in state_attr('sensor.ytube_music_player_extra', 'search') -%}
          {{media.type}},{{media.id}},{{media.title}}
        {% endfor%}

7. sqlite

7-1. Let model generate a query

• Without examples, a query tries to fetch data only from "states" table like below

  Question: When did bedroom light turn on?
  Query(generated by gpt): SELECT * FROM states WHERE entity_id = 'input_boolean.livingroom_light_2' AND state = 'on' ORDER BY last_changed DESC LIMIT 1

• Since "entity_id" is stored in "states_meta" table, we need to give examples of question and query.
• Not secured, but flexible way

- spec:
    name: query_histories_from_db
    description: >-
      Use this function to query histories from Home Assistant SQLite database.
      Example:
        Question: When did bedroom light turn on?
        Answer: SELECT datetime(s.last_updated_ts, 'unixepoch', 'localtime') last_updated_ts FROM states s INNER JOIN states_meta sm ON s.metadata_id = sm.metadata_id INNER JOIN states old ON s.old_state_id = old.state_id WHERE sm.entity_id = 'light.bedroom' AND s.state = 'on' AND s.state != old.state ORDER BY s.last_updated_ts DESC LIMIT 1
        Question: Was livingroom light on at 9 am?
        Answer: SELECT datetime(s.last_updated_ts, 'unixepoch', 'localtime') last_updated, s.state FROM states s INNER JOIN states_meta sm ON s.metadata_id = sm.metadata_id INNER JOIN states old ON s.old_state_id = old.state_id WHERE sm.entity_id = 'switch.livingroom' AND s.state != old.state AND datetime(s.last_updated_ts, 'unixepoch', 'localtime') < '2023-11-17 08:00:00' ORDER BY s.last_updated_ts DESC LIMIT 1
    parameters:
      type: object
      properties:
        query:
          type: string
          description: A fully formed SQL query.
  function:
    type: sqlite

Get last changed date time of state	Get state at specific time

FAQ

1. Can gpt modify or delete data?

   No, since connection is created in a read only mode, data are only used for fetching.

2. Can gpt query data that are not exposed in database?

   Yes, it is hard to validate whether a query is only using exposed entities.

3. Query uses UTC time. Is there any way to adjust timezone?

   Yes. Set "TZ" environment variable to your region (eg. Asia/Seoul).
   Or use plus/minus hours to adjust instead of 'localtime' (eg. datetime(s.last_updated_ts, 'unixepoch', '+9 hours')).

7-2. Let model generate a query (with minimum validation)

• If need to check at least "entity_id" of exposed entities is present in a query, use "is_exposed_entity_in_query" in combination with "raise".
• Not secured enough, but flexible way

- spec:
    name: query_histories_from_db
    description: >-
      Use this function to query histories from Home Assistant SQLite database.
      Example:
        Question: When did bedroom light turn on?
        Answer: SELECT datetime(s.last_updated_ts, 'unixepoch', 'localtime') last_updated_ts FROM states s INNER JOIN states_meta sm ON s.metadata_id = sm.metadata_id INNER JOIN states old ON s.old_state_id = old.state_id WHERE sm.entity_id = 'light.bedroom' AND s.state = 'on' AND s.state != old.state ORDER BY s.last_updated_ts DESC LIMIT 1
        Question: Was livingroom light on at 9 am?
        Answer: SELECT datetime(s.last_updated_ts, 'unixepoch', 'localtime') last_updated, s.state FROM states s INNER JOIN states_meta sm ON s.metadata_id = sm.metadata_id INNER JOIN states old ON s.old_state_id = old.state_id WHERE sm.entity_id = 'switch.livingroom' AND s.state != old.state AND datetime(s.last_updated_ts, 'unixepoch', 'localtime') < '2023-11-17 08:00:00' ORDER BY s.last_updated_ts DESC LIMIT 1
    parameters:
      type: object
      properties:
        query:
          type: string
          description: A fully formed SQL query.
  function:
    type: sqlite
    query: >-
      {%- if is_exposed_entity_in_query(query) -%}
        {{ query }}
      {%- else -%}
        {{ raise("entity_id should be exposed.") }}
      {%- endif -%}

7-3. Defined SQL manually

• Use a user defined query, which is verified. And model passes a requested entity to get data from database.
• Secured, but less flexible way

- spec:
    name: get_last_updated_time_of_entity
    description: >
      Use this function to get last updated time of entity
    parameters:
      type: object
      properties:
        entity_id:
          type: string
          description: The target entity
  function:
    type: sqlite
    query: >-
      {%- if is_exposed(entity_id) -%}
        SELECT datetime(s.last_updated_ts, 'unixepoch', 'localtime') as last_updated_ts
        FROM states s
          INNER JOIN states_meta sm ON s.metadata_id = sm.metadata_id
          INNER JOIN states old ON s.old_state_id = old.state_id
        WHERE sm.entity_id = '{{entity_id}}' AND s.state != old.state ORDER BY s.last_updated_ts DESC LIMIT 1
      {%- else -%}
        {{ raise("entity_id should be exposed.") }}
      {%- endif -%}
