A potential alternative for haters of the cloud: I got an Airthings Wave+ unit. Home Assistant can immediately connect to it via Bluetooth LE and get readings.

It'll be auto detected if it's within range when you put the batteries in, assuming your HA install has Bluetooth support (mine worked out of the box with a Pi 3B.) (Specifically the Wave+ though; the hub apparently will want to connect over wifi instead, so I think it's better to just go for the Wave.)
