Well, I took me some time to get into Angular but a new enhanced version of this widget is available in beta. It now uses the hourly forecast to get the closest to noon data to display for the coming days. This way you get a more accurate daily forecast stil using the free API.
Before I pull it to master, I would appreciate it if someone with more experience with Angular can take a look at my code to see if it makes sense or not. For instance, I’ve got my doubts about the use of $interval. Fork if you like. Please add the items from the items file.
For everybody else, please wait with this beta until its reviewed.
