SONOS commands to group players

[david.rombaut@gmail.com]

Hello, is anyone familiar with commands to group players?
I have found a way to get a player out of the group with this command:

Code:

upnpavcmd(IP_address, 1400, 'BecomeCoordinatorOfStandaloneGroup')

Unfortunately I cannot seem to find anything that does the opposite. I already tried to find the proper commands through Wireshark but it seems rather complicated to me.

Thanks in advance for any suggestion.

BR, David
