Just asked this same question on the FaceBook group but I'll give it a try here. Just setup my new Atlas weather station that's replacing my old 5-1. Everything appears to be working fine but both the My Acurite and Weather Underground sites don't show my current info yet. Is there a delay until these sites actually start showing the current weather data? It's been a couple of hours so far and nothing yet.
Settings on both sites show my new Atlas system though, just not broadcasting it.
Thanks
Check the Access "splash page" with a web browser (use the IP address assigned to the Access). If your wunderground information is there and correct, it should be good.
If it's not there, then something in your setup hasn't been completed yet, or something is preventing your Access from receiving its setup info from myAcurite.
Valid weather station data should be flowing to myAcurite first. Wunderground will follow about 10 minutes or so later.
