Z-wave triggered weather and picture slideshow


I’m new at this and don’t know where to start.
I would like a screen to come out of sleep and display local weather forecast and stream a picture slideshow when presence is detected by a Z-wave motion detector.

Intention is that nobody needs to touch anything and that the screen comes automatically on and off again, based on detected presence.

I was thinking of hooking up an RPI2 to a wall mounted screen and have the RPI2 receive triggers from my Openhab server.

Are there easy ways to do this ?

Kind regards,
