Tommy:
Much appreciated as I would very much like to integrate the control of my SONOS into my Crestron system, but have all but given up based on earlier conversations...I am, however, checking one last thing with my porgrammer that being whethe rit would be possible to build an interface between between SONOS' computer application and the Crestron control system as this may be an easier route...
Await your response...
As I now understand it from PM:ing my friend they no longer play nice together since the latest Sonos SW upgrades. When you make a call Sonos reset the server, making it hard for anything else to control the system. He doesn't use the combination at home, and only partly at work (and they do Crestron programming, among other things).
Edit: I got it explained more thoroughly. Sonos mesh net uses DHCP and when something, like a remote, is inactive for a while it's thrown out to free up an IP address. Crestron, however, uses fixed IP addresses. To get this to work together they ping'ed the server so the Crestron units weren't thrown out due to inactivity. But with the SW change, the server was reset for every ping. They worked on a workaround for that problem, and were finishing it, when they learned that one (other) company would get the exclusive Sonos rights here in Sweden. So it wasn't interesting finalizing it since they couldn't do custom installations selling Sonos. They can use the Crestron for stop/play, but the feedback thing isn't ready - and the visual controller is one of the main selling points for Sonos...
