I am developing my own weather station and software. Currently it is just logging temperature, which it is submitting to Wunderground every 5 minutes (PWS ID IGREATBR4). It is mostly working fine, but at 11:20 today Wunderground recorded 0 degrees C (even though the submission was correct, according to my log), and it missed the submission at 11:25 completely (this submission seemed to be correct too). Any idea why this might have happened? Is there anything I can do to prevent it from recording bogus temperatures? Have other people experienced things like this?
Thanks - Rowan
