To group tables within the Sobro App, press the Edit button on the upper right hand corner of the screen. You can then press "Add Group" and drag and drop your tables into the new group. Remember to name your Sobro group when you're done!
Grouping tables in the App does not automatically pair the speakers, it is for control of the lights and sleep system ONLY. Speakers can be paired using the button on the back of the Sobro.
