Perhaps others may have seen this. When I restart weather display after the computer has been off, on the console display, I get large positive spikes on the graph humidity trace, (as much as 8%) and on the temperature minus spikes of around 8 deg, and minus on the dewpoint (around 4 deg). These spikes only happen on restart. On restart of the computer,the data that is entered for the period of time that the computer is off, comes from the meteohub which runs 24/7, so I am puzzled as to why this is happening. Ideas anyone?
