Control KNX via smartphone/web

[braest]

Dear,

What are your experiences/suggestion when it comes to a system to interface with KNX/EIB over an KNX/IP router.
Some requirements :
- it needs to be visual and usable from a smartphone
- it should have widgets to integrate other datafeeds like news, temperature, ... from internet sources
- it would be nice if it integrates with other systems like sonos, ...
- it should be user friendly to program and setup

Thanks!

Tim
