BlueAir AQI Readings Now Working
Magic "Mirror"

The update that came in shortly after my last post on the subject did fix reading data from the air quality sensor on a Blueair air purifier via the Home Assistant integration!

To get the data out of home assistant I'm using an automation to write the sensor reading out to a file, then converting it from pollution concentration to an intermediate air quality index value using python-aqi.

action: notify.send_message
metadata: {}
data:
  message: '"{{ states(''sensor.blue_pure_front_pm_2_5'')|float }}"'
target:
  entity_id: notify.file

I'm now pulling values into a little custom chart module for MagicMirror. The 'ba-aqi2.5' line tracks values from the purifier. It's giving similar readings to the sds011 sensor I have set up in another room, displayed as the lines labeled 'aqi2.5' and 'aqi10'.
