Indoor Air Quality

Bad indoor air quality may make concentration worse as well as exasturbate allergies. As such I would like to take care to improve air quality, both for my home office and my bedroom.

Measuring

It's hard to improve what you can't measure, so the first step is to get some sensors.

Aranet4

I bought the Aranet4 HOME to measure CO2. This device works great, the downside is that its a bit pricey. Preferably I'd get two, one for my bedroom and one for my work enviroment, for now I started off by just buying one.

I'm using a Home assistant Yellow as my hub for my smart home. I would have liked to connect the aranet4 to it, which I think is possible, but I currently don't have bluetooth on the Home assistant Yellow.

The Aranet4 measured CO2 but it doesn't measure Volatile Organic Compounds (VOCs), so I'll still need a device for that.

DIY device

Instead of buying a second Aranet4, I might try and make my own device. Jeff Geerling got a blog post and YouTube video building one that looks good.
