Hey Wayne,
Henk here, I am just a few clicks down the road (Dayboro).
I experience similar, the humidity, for example, is 20% off. Personally, I am not too worried about it at the moment and I write it off based upon the sensor locations.
A question I have is your Formaldehyde working?

LOL.. according to the uradmonitor site we are in China… I know China has bought half of Australia farming and agriculture land, but I believe it is still Australia, not China. (Then again with the day to day changes in Canberra we might be China by now… who knows).
