When multiple WiiM devices are grouped, how can you use one remote to adjust the group volume?

Usage Tips

You can pair the remote to your group leader (the master device) and then use the remote to adjust the volume for the group. 

To locate the group leader, please launch the WiiM Home App, navigate to the 'Device' tab, and find the first device in the group. 

Notes: Except for the group volume control, you can use the remote to control other functions on the master device, even in a group.
