Davis Vantage Vue Weather StationI bought this weather station with the Weatherlink IP software in September 2010 purely as a way of monitoring the weather for sailing. It has been useful way beyond what I originally anticipated. I only bought the Weatherlink IP logger because I'm a gadget nut and couldn't resist the idea of plugging it into my home network and sending data to weatherlink.com and the weather underground; however, this functionality alone meant that over the recent cold winter I was able to monitor the internal temperature of my home while I was away on vacation, and thereby watch for any conditions that may have resulted in frozen pipes. Similarly, the indoor humidity sensor has provided visibility for observing the effects of provisioning new dehumidifiers around the house for keeping condensation under control.
The only problem I have encountered was some crashing of the Weatherlink software running on an old laptop - however, this was solved quickly enough by upgrading the Microsoft .NET framework to the latest version. It has been stable since.
All in all, a really excellent, high quality piece of kit. I highly recommend it.
