The Indoor Air Quality (UK) HACS Integration and Sensor

Now that I have a number of AirGradient sensors around my house, I have all sorts of data I can make use of about the air quality inside it. I now have to figure out how to make use of all that data. Creating a single unified data point for general air quality based on the AirGradient data is the first thing I’m going to do. To do this, I’ll make use of the IAQUK HACS integration.

Adding TVOC to the AirGradient

Once I had my baseline AirGradient sensors built and configured, I wanted to add a few more sensors to it. One of the sensors to be added is an SGP30 TVOC sensor (Total Volatile Organic Compounds).

Adding an LPS22 to AirGradient and Building a Custom Sensor in EspHome

I picked up some extra sensors for my AirGradient DIY kits and didn’t realize at the time that they’re not officially supported in EspHome. So with that I went on the journey of adding my own custom sensor code to EspHome to run them.

Making the AirGradient DIY

I’ve been working on getting air quality measurements going in and out of my house, however there are a lot of cloud connected sensors out there. I wanted these to be all local, though I wouldn’t mind adding to the public datasets for air quality. I ended up coming to AirGradient as the option that I decided to use, these use all open hardware and can be flashed with the custom AirGradient firmware, or with EspHome. I went the DIY route as well to save some money (and I’ll be customizing them a bit too).
