I've been using Thingspeak to post my data from a ESP8266 for over a year. Sometimes, like right now wunderground stops listening to the posts. I followed everything here: http://wiki.wunderground.com/index.php/PWS_-_Upload_Protocol
Is the upload protocol currently down or something? I've troubleshooted the http posts and it is sending correctly so that looks to me like a problem on wunderground side.
