I recently bought a Vantage Vue, and have been quite happy with it. However, until it arrived, I didn't know it would just 'plug n play' into my Mac so I could start recording data. So I bought an Envoy, which I again thought was plug n play, and found out the wire in the photo of the units, doesn't come with it. So I bought the Weatherlink IP. Those last two purchase were more than what I originally paid for the Vue, console & ISS!
I can return the Envoy, but I prefer it to the Console. I have the console as a '2nd screen' upstairs, and have the Envoy running 7/24 downstairs connected to my router and Mac mini running WeatherCat.
And, what I just found out, like the console, you need to adjust the settings in the Envoy so it works properly. i.e. lat/long, elevation, etc etc...Now that is a pain in the *** to so on a Mac, since the WeatherLink IP and Envoy DO NOT support Macs. I ended up running a trial version of VMWare Fusion to install WeatherLink for PC on my Mac, made the adjustments, now all works well.
I really strongly suggest the use of the IP version of the Weatherlink, since it is plug n play, and if used on a console, should be easier to setup.
