If you're thinking of implementing the ability of using a weather sensor on the local network, might I suggest you add the ability to custom parse a JSON response? I have a uRad Monitor that lets you pull the data. I can help to explain the data if you need.

I love BI Tools, but I'd love it even more if you could add the option to pull the weather from a local device, especially a uRad Monitor... the RESTful API for it is very well documented here, starting on page 5...
