Would like to be able to pull weather data from the apps on my phone. I find wunderground to be much more accurate no matter where you are. Even the stock Apple weather app is more accurate than the LaMetric weather data.
If your looking for low power, it can happily run on a Raspberry Pi - this would probably work and open up a system that allows reporting to Weather Underground as well as various live feeds - our output is at weather.casa.ucl.ac.uk if your interested, so live graphs etc and it links into the lametric...
Just a thought,
