I've got a few of the airthings bluetooth units and a wifi gateway that handles bluetooth -> wifi. Works well, sensors seem to be accurate and correlate with things like radon (which dropped once mitigated), CO2 peaks (when more people are around or gas oven is on), temp, humidity etc.
They have a github repo at https://github.com/Airthings and have code for things like uploading data to a local grafana.
It was basically turnkey, the gateway works on batteries or gasp a usb-c. Batteries on the BT only widgets do last a good fraction of a year. I'm using the cloud hosted dashboard, but bought it because I could migrate local when I have the time to setup.
EDIT: I have the viewplus (not waveplus), that acts as a Bluetooth <-> WIFI gateway and has a PM2.5 sensor the view plus does not, and does NOT have any code I've found to read it for non-cloud use.
