Hi Russ and all,
I follow that link which shows me the same data as what I see in the "Raw weather data" link on findU.com's main page. It confirms that data points, which are supposed to show every 5 minutes, are commonly missed, often 2 times in a row. What I am looking for is an explanation for and hopefully a fix for the anomaly. It is quite possible that the data export configuration in my WiFiLogger (addon to Davis Vantage Vue) device is not quite right, but I have no guidance yet as to what the problem might be. It would also be quite useful to know whether I am the only one to see this anomaly. If I am, then we know where to look.
