Abstract
An example implementation may involve receiving, via a radio interface, a radio transmission indicating a particular playback device of a media playback system. Based on the received radio transmission, the implementation may further involve determining that the device is within a given proximity to a zone of the media playback system that includes the particular playback device. Based on determining that the device is within the given proximity to the zone of the media playback system, the implementation may also involve causing the graphical interface to display an indication of (i) an identifier of the zone and (ii) a characteristic of the zone.
