What is Home Assistant Google Air Quality all about? I’ll be totally honest with you — I rarely thought about air quality. Maybe once or twice a year, if there was a wildfire in the news or a smog alert.
Weather? Sure. Every morning. But the actual air I breathe on a random Tuesday? It just wasn’t on my radar.
And then I had a thought that kind of changed everything.

What If My Home Assistant Could Just Tell Me? 🌬️
I was scrolling through the Home Assistant integrations one day and stumbled on something I didn’t know existed — a Google Air Quality integration. And I thought: “Wait… I can get real-time air quality data right in my dashboard?”
So I set it up. And suddenly I had all these sensors with scientific names and numbers staring at me. PM2.5, Ozone, Nitrogen Dioxide… cool, but what does any of that actually mean?
That’s when the idea hit me — what if I just handed all of that data to an AI and asked it: “Hey, is the air okay today? And explain it like I’m a normal person.”
Home Assistant Google Air Quality — Wait, This Exists?
Turns out Google has an Air Quality API that gives you real-time data about the air around your location. And Home Assistant has an official Home Assistant Google Air Quality integration that connects to it.
Once you set it up, you get around 12 sensors:
- An overall Air Quality Index score (0–100)
- A category label (Excellent, Good, Moderate, Low, or Poor)
- The dominant pollutant (the main bad thing in the air right now)
- Individual readings for PM2.5, PM10, Ozone, Nitrogen Dioxide, Sulphur Dioxide, Carbon Monoxide
That’s a LOT of data. And if you’re a regular human — not an atmospheric scientist — most of those names and numbers mean absolutely nothing.
Which is exactly why the AI approach works so well here.
So I Built It — And It Works Beautifully
Here’s how the whole thing flows:
- Home Assistant Google Air Quality integration pulls the data every 60 minutes
- When the air quality category changes, an automation triggers
- All sensor values get bundled together and sent to an AI
- The AI writes a short, friendly summary
- I get a notification on my dashboard
The result looks something like:
“Air quality is moderate today 🌤️ The biggest concern is fine dust particles (PM2.5). Nothing serious, but maybe keep the windows closed and save the outdoor run for tomorrow.”

What You Need to Make This Work
Without going into all the details (that’s what the live stream is for!), here’s the basic structure:
Piece 1 — The Data Source
The Home Assistant Google Air Quality integration. You need a Google API key and a billing account (Google gives you 10,000 free calls per month — more than enough). The integration does the rest.
Piece 2 — The AI Brain
The Ollama-HA app running in Home Assistant with a cloud or local AI model. This is what reads your sensor data and turns it into a human-friendly summary.
Piece 3 — The Automation
A YAML automation that connects the dots. It watches for changes, bundles the sensor data, sends it to the AI, and delivers the result as a persistent notification.
Each piece is pretty straightforward on its own. The trick is getting them all connected and talking to each other correctly — which is exactly what we’ll do in the live stream.
Why This Automation Actually Matters 🫁
Here’s the thing I didn’t appreciate until I started using this setup:
Air quality isn’t something that’s bad once a year during wildfire season. It changes constantly. Your area might have perfectly fine air in the morning and elevated PM2.5 by afternoon — because of traffic, construction, or just a shift in wind direction.
And for people with asthma, allergies, or small kids — knowing about these changes can genuinely make a difference. Even a simple “keep the windows closed today” can save someone from a rough afternoon.
With the Home Assistant Google Air Quality integration and a bit of AI magic, your smart home watches the air for you. No effort. Fully automatic.
That’s the kind of automation that isn’t just cool to demo — it’s useful every single day.

The Part Where It All Comes Full Circle
Looking back, it’s kind of funny. I went from barely ever thinking about air quality to having my smart home actively watch it for me every single day & every single hour. And every time I get one of those friendly little notifications, I think: “Yeah, this is why I love Home Assistant.”
If you’re into smart home stuff and you want to try something that’s genuinely practical — this is a great project. It’s not hard, it doesn’t cost anything to run, and you’ll actually use it every day.
