i have the htc hub enabled to run in the background, however my pinned weather tiles don't seem to update until i open the htc hub. i don't have constant internet connection, i enable it from time to time. i tried leaving it enabled for some time (10 minutes or so) but the tiles didn't update. do you know how often do the weather tiles refresh themselves (every hour etc.)?
I just switched to accuweather from theweather channel last night and went in this morning to settings and enabled live tile which was apparently off by default thew live tile seems to working just fine.
To be honest I can not understand why HTC bothered with their weather and time hub. It looks like it was made simply to mirror their Android products, but why would they do that -- Windows Phone 7 is a completely different and unique OS?
That said, Vadret is the weather app I use. It updates every 30 minutes (I think) but it takes about that long to start displaying information on the tile when it is first pinned. One cool feature it has is it lets you choose the style of your tile. You can choose to have the tile keep with the Metro UI's minimalistic look or you can have a graphic of the current weather conditions. The app itself is also very slick. I tried Vadret, the Weather Channel app, and the simple one by Microsoft, and came away perferring Vadret. Of course, not everyones opinion will be the same.
I also have the HTC hub. Until about two weeks ago, none of my weather apps including HTC would update unless I opened them. I have received a number of updates over the last two weeks and now all live tiles including the HTC hub update automatically and often. I have version 2.3 (build 2121.38311) for the HTC hub.
I always thought it was 3 hours. HTC Hub has worked fine for me, granted I don't care for the weather THAT much, but when I do it works out for me. I mean, how often does the weather change?
3 hours was the default setting in the previous build I mentioned, but you could set it as low as every minute! Selecting this option prompted a confirmation screen with a warning about the adverse effect it would have on battery life. (!)
Here in Saskatchewan, the long term forecast, and current conditions, can change dramatically (10C or more) inside an hour.
