Thanks.
What I meant about the app not being supported and multiple locations, is that the new lacrosse "app" allows you to monitor many different sensors. So you could put the weather station on your house, then add temp sensors to garage, loft, greenhouse etc, and monitor them all on one app. However this doesn't support the 330-2315, and in fact seems to support only devices not yet released, and planned for release in US only.
You're correct in that I could monitor on WU, however quite like the ability to cycle through locations on the Oregon to check at a glance those locations on the display, without going to WU.
The forecast bit seems similar to Oregon and so on, and is useful for wife and family. I would expect this device to keep publishing to WU as long as it's alive.
It's been reduced in price, hence my interest, as I too like the display.
