I checked “Air Quality Binding” with “openHAB 2.3.0 Release Build” on Windows and openHABian without problems.
What OS and java-version do you use?
When do you get this warning?
Post your AirQuality-configuration please.

Sorry Harry, I missed your response.
I have just checked todays logs and I see the error every hour.
I am on RPi using openhabian
