@Ross A node server for the Davis WeatherLinkIP version 1 API is now available in the node server store.  It's called DavisWeather. It's all based on the demo data available from the API documentation you pointed at which may be different from what an actual station reports.   If you find that something important is missing, set the log level to debug and capture the data being returned for your station and send it to me so I can update the node server.
