Play state not updating when devices are grouped

Hi,

I use Vera and the Sonos plugin to turn on my amplifier (wall plug) when I start playing music on my sonos and turn it off when the music stops. It is working great if the sonos player is playing alone, but if it is grouped with another player, and the other player is the master, it is not working. The play-state is not updated and the status message for the sonos player is saying “Group driven by xyz”. The result is that my amplifier is not turning on and off…

Please help!
