Has anyone here written seen or been involved with integrating a DIY Air Gradient air quality monitor. I recently jumped into it with the DIY Pro presoldered version. Looks pretty nice, monitors several thing and you can enhance it by adding your own sensors.
The default setup monitors CO2, Pm2.5 and PM10, temp and humidity. Looks like it will easily add TVOC's as well. I am thinking about creating a virtual driver for it and integrating it into HE. The device has the ability to post its stats to a remote system so with MakerAPI it shouldn't be hard to get it into HE.
