Is there a Sonos widget for iOS 8 and/or Mac OS X?

At home I have a Sonos system. The only thing is to change the track/volume you've got to unlock your phone, open the app, make sure your on the correct group then click the next/previous along with the volume.

Because of this is there a widget to control the Sonos (1st party or not)? This is so I can control it without having to unlock my iPod and open the app.

I would like it if there was one for Mac (Yosemite) as well as iOS 8.

Thanks
