so it's been a while, so here's an update:
I created the new connection screen and modules for switches and sensors. I'm currently looking for screenshots of modules I don't own myself (see other thread I created here)
Next steps are updating the UI when one of the modules are changed from another client and adding push notifications.
I'm currently focussing the UI work on WP8.1, all the actual code is being shared across Windows store and Windows Phone. So once the app is finished I'll only need to do some UI work to get it to windows store as well
