Hi David, I am curious about that too. I checked on Wunderground stations all over Boulder, over 50 of them and some across the state, and every station updated every 3 to 5 seconds except for my station. Mine updates every 1 to 2 minutes. It was actually more than that at one point, but I would still rather have a closer to real-time update. I've been a weather forecaster over 30 years, and I am not new to running weather stations. In the past, I have always had them hooked up to my own website. This is the first time I am sending data to another server that is not my own. The ambientweather.net has a top reporting time of 1 minute so from them I don't have a choice changing the reporting time to under a minute. I find it really strange that Wunderground is mirroring that very same 1 to 2 minutes that I'm getting from ambientweather. And one last thing, I actually have a later firmware AMbWeatherv4.3.2 then the 2 weather stations a couple of blocks away.
Thanks again for taking your time to chat with me on this. I really appreciate it! -- Greg in Boulder
