Home Assistant GPT is a custom GPT assistant that interfaces with the Home Assistant API, allowing you to control and query various home devices with ease. This integration leverages the power of GPT-4 to provide an intuitive and responsive experience for managing your home automation setup.

• A ChatGPT Plus account
• Your Home Assistant instance must be web facing.
• You will need to enable the Home Assistant REST API - https://developers.home-assistant.io/docs/api/rest/

• Device Control: Interact with lights and automations.
• Weather Updates: Get summaries and recommendations based on the weather.
• Customizable Entity List: Tailor the GPT to your specific Home Assistant setup.

Here's an example of the GPT calling an automation to turn on the TV in my house.

You can see on the data shared that it determined the correct automation to run, just from the name.

1. GPT Initialization:

   • Create a new GPT named 'Home Assistant'.
   • Use the following prompt, updating it with your entity list: Prompt Link

2. Action Integration:

   • Add Actions using the provided OpenAPI Spec. Ensure to replace the URL with your public address: API Spec Link

3. Authentication:

   • Add an API Bearer Token for authentication. This token should be a long-lived token generated from your user page in the Home Assistant API.

4. Finalizing GPT Setup:

   • In your GPT settings, turn off "Use conversation data in your GPT to improve our models" for privacy.
   • Test the setup in the preview.

5. Publication:

   • When ready, publish the GPT. It's recommended to set it as Private for security.

• Lights: Control and set colors of light entities (e.g., light.office_lights).
• Automations: Trigger automations for various home activities (e.g., automation.boost_main_heating).
• Weather: Provide weather summaries and recommendations (e.g., weather.met_office_brighton_racecourse_3_hourly).

• Voice Control: Integration with OpenAI's Whisper model for voice commands.
• Expansion of Supported Devices: Increasing the variety of controllable entities.
• User Experience Improvements: Continual refinements for smoother interactions.

Contributions are welcome! This project is in its early stages and open to ideas, improvements, and creative enhancements.
