Are you still staring at Home Assistant notification walls instead of a good summary? What about Home Assistant voice commands? Do they work the way you want? It’s easier (and cheaper) to integrate AI with your smart home than you think.
Both OpenAI and Google offer free API tokens
You just have to feel comfortable sharing your activity.
It sounds crazy, but both OpenAI (ChatGPT) and Google (Gemini) Offer free API access to the company’s cloud-based models. This means you can use GPT-5.5 or Gemini 3.5 Flash without paying a dime.
All of this is done through the free tiers of both companies. The only drawback to using cloud models for free is that you share your inputs and outputs with them. However, if you’re already using ChatGPT or Gemini through the desktop or mobile apps, or website, then you’re already sharing that information with them.
So if you’re okay with sharing input/output tokens with Google or OpenAI, you can use either model completely free in your smart home.
Adding AI to Home Assistant is a simple task
You don’t need to be a programmer to set this up.
So how do you integrate AI with your smart home? Well, start in Home Assistant. Simply navigate to Settings > Devices and services and then search for OpenAI for ChatGPT or Google Gemini.
From there, you’ll need to add your API key from either service. Get an API key It is a simple process. Basically, you just need to sign up for an account on OpenAI or Google Developer Platform, and you’re good to go. With OpenAI, there is one more step you must take enable sharing at API levelbut after that, you’ll be ready to go.
Once you have an API key, simply enter it into Home Assistant and you’ll be pretty close to automating your smart home with AI. After adding the API key to Home Assistant, there are several ways to use AI within Home Assistant, but it all starts with adding that API key.
AI is the perfect way to make your smart home look futuristic
Just be sure to monitor your token usage
The first thing you could configure is voice assistantsheading to Settings > Voice assistants and then create a new voice assistant or edit an existing one. You’ll want to configure the conversation agent on any AI platform you configure.
Then go to Expose and be sure to only expose the devices or entities you want the AI to be able to control. I would be a little demanding with what you expose.—You may not want to give OpenAI or Google access to unlock or lock your home, or view your cameras, for example. However, the more you give AI access, the more you can do in your smart home.
Another option would be to use ChatGPT or Gemini to summarize (or personalize) your notifications. Instead of receiving 37 notifications throughout the day, such as “Front door open”, “Garage door open”, “Garage door closed”, “Washer finished”, “UPS package delivered”, etc., you can receive a summary notification that would look like: “While I was away, a UPS package was delivered at 2:14 pm, the garage door was opened twice, and the washer completed its cycle. No security-related issues were detected.”
You can also use AI within camera plugins, such as Frigate or Scrypted. This means you can use AI to not only say “Person detected” at your front door, but also to say “A man in a red shirt walks down the driveway with a cardboard package.”
These are just a few examples of ways you could use AI in Home Assistant, but the opportunities here are actually endless. The only thing you need to keep in mind is the use of tokens. A few events here or there probably won’t leave you without free tokens every day, but a busy household could get expensive quickly.
I would recommend setting some guidelines with Google or OpenAI on how much you would be comfortable spending on tokens per day.
You’ll most likely be able to use the service completely free, but if there are a lot of packages and door opening requests on any given day, you don’t want to wake up to a $100 API bill.

Don’t underestimate the power of AI in your smart home
You might think your smart home is perfectly fine without AI, and you’d be partly right. He does operate without AI, but your smart home could be much smarter with AI in the mix.
If you’re worried about the security implications of using ChatGPT or Gemini to run your smart home, then it’s really simple run it from a locally running AI on one of your computers.
In reality, you should be running your smart home with AI, whether it’s a cloud-hosted model or a locally hosted model. Home Assistant combined with AI creates a smarter home.
