Hi … I’m on 3.03 but I noticed this issue in 3.02 as well.
My temp last 30 day chart is showing an odd value (maybe more) my XML data says that the max temp yesterday (Sunday 12th) was 8.7c - the temp chart for the last 24 hrs agreed. Max temp for -1 day in the 30 day chart is shown as 14.0 deg which is far too warm.
