OpenAI’s powerful chat models brings your Home Assistant to life. You can finally build the smart home you have always wanted – a lifelike voice assistant that can be spoken to using natural language and is powerful enough to interrupt your commands and take action. This guide will help you set up an OpenAI ChatGPT integration in Home Assistant – and it’s free!
We will use Sage from Homeway.io, which provides AI services to power Home Assistant’s Assist and Voice. Sage offers assistant chat powered by ChatGPT, DeepSeek, Claude, or Gemini LLM models. It also enables free speech-to-text and text-to-speech, featuring over 50 lifelike voices from OpenAI, Azure, AWS, and Google.
But that’s not all, Sage’s powerful engine allows:
- Home Control – Sage deeply integrates into your Home Assistant to give the chat model a complete understanding of your home and enables it to take action on any device.
- Intelligence – Sage can do web searches for answers, get weather forecasts, look up live sports scores, and more.
- Personalization – Sage saves memories of your preferences and allows you to set timers, reminders, and alarms.
Homeway is committed to your privacy, and Sage is no exception. Sage is built in the most privacy forward way possible. We send a minimal amount of anonymized data to each AI provider and immediately delete the data when the processing is done. See our privacy policy for complete details. Homeway is 100% community-supported, so if you want to help, consider becoming a supporter!
Install the Homeway Add-on
Installing the Homeway add-on for Home Assistant takes about 20 seconds and requires no technical knowledge. If you can access your Home Assistant dashboard, you can install the add-on.
Add The Sage Integration
Once Homeway is installed and connected to your account, Home Assistant will discover Sage’s Wyoming integration. To enable it:
- Open Home Assistant in your web browser.
- Go to the Home Assistant settings.
- Select “Devices & services”
- Find the box in “Discovered” for Homeway Sage.
- Click the “ADD” button.
If you don’t have a Wyoming box in your Discovered section, follow this guide manually to set up the integration.
Create the Sage AI Voice Assistant
Now that the Homeway Assistant integration is ready, head to the Home Assistant Voice Assistant settings to configure it.
- Open Home Assistant in your web browser.
- Go to the Home Assistant settings.
- Select “Voice assistants”
- Click the “+ ADD ASSISTANT” button.
- For “Configuration”
- Name – Anything you want it to be, we suggest “Homeway” or “Sage.”
- Set your preferred language.
- For “Conversation agent”
- Select “Homeway Sage”
- Be sure to enable “Prefer handling commands locally.” This will allow the built-in Home Assistant model to handle actions relating to your smart home devices and pass everything else off to Sage.
- For “Speech-to-text”
- Select “Homeway Sage”
- Set the language you want to speak in.
- For “Text-to-speech”
- Select “Homeway Sage”
- Set the language you want to speak in. Most voices support multiple languages and can even switch in real time!
- Select a speaker voice.
- Homeway Sage offers over 25 voice models from OpenAI, Google, Azure, and more. Try different voices to see which you like best!
- When you’re done, select “CREATE” at the bottom to make the new assistant profile.
- When the profile pop-up closes, locate the assistant profile you created, click the three verticle dot menu, and then select “Set as preferred.”
Setup Your Home Assistant Voice
If you have a Home Assistant Voice (the standalone “Alexa-like device”), make sure it’s configured to use your Homeway Sage assistant profile. To do so, look in your Home Assistant devices list for “Home Assistant Voice” and click it to see its settings. In the “configuration” box, ensure that “Assistant” is set to your Homeway Sage profile.
What Will You Try First?
Now that you have Sage with OpenAI’s ChatGPT set up… try it! Go to any Home Assistant dashboard and open Assist by selecting the chat icon at the top right. You can type text messages to Sage or use your voice.
Be sure to try:
- What’s the weather forecast for today?
- Turn on the Kitchen lights.
- Can you remember to call me <your name>?
- What’s happening in my local news?
- Remind me in 1 hour to take out the trash.
Remember Sage has the power to:
- Create memories about you and how you want to interact with Sage. Sage will make memories independently, but you can also explicitly ask it to make memories, list its current memories, or tell Sage to delete memories.
- Set reminders, timers, and alarms for future events up to 20 days away.
- Control or report information from devices you have set up in Home Assistant.
- Search the web for facts, breaking news, business details, and more.
- Get live weather conditions and future weather forecasts for your local area.
- Get live sports scores and stats or report information about past games.
- Access internet webpages to gather information.
The only limit is your imagination; Sage is standing by and ready to help!
