Problem with update Sonos state


I’ve latest version of Sonos plugin and the UPnP plugin enabled.
I noticed that after power failure that affects Sonos, its status stops to be properly reported.
So Vera never notices that Sonos is offline and (after power on) it has no music source selected.

I’ve tried to figure out how can I manually pool Sonos - but nothing worked in my case.
Is there a way I can force Vera to update Sonos device status?

Also I noticed that SetURIToPlay() also starts playing music. So basically in my case it works the same as PlayURI(). Is there a way I can set URI but without playing it immediately?
