KNX audio and multimedia with Link’nX: Sonos, BluOS, Denon, TV

Link’nX controls the audio players and TVs declared on the gateway, from the KNX bus or in a scenario: playback, volume, mute, favorites or presets, inputs, groups. Each brand has its own declaration, actions and KNX gateway table, with its own commands and DPTs. Choose the path according to the brand and the model.

For Sonos, start by declaring the speaker; the Sonos troubleshooting guide answers the most common problems.

  • The DPT 1.001 pulse commands of Sonos, BluOS, Denon/HEOS and Samsung react to the value 1: the 0 sent on release does not request the opposite command.
  • Absolute volume is set in DPT 5.001, from 0 to 100, for Sonos, BluOS, Denon/HEOS and Samsung. Relative commands differ: signed offset from -100 to 100 in DPT 6.010 for Sonos, 2 dB step for BluOS, step from 1 to 10 in DPT 5.001 for Denon/HEOS.
  • Some functions only exist in scenario actions: BluOS input and groups; Samsung input, channel, app and key. The Sonos favorite, group and URL rows of the table require a procedure set up with support.
  • To power on a Samsung TV over the network, the declaration must include its MAC address, with a compatible model and Wake-on-LAN allowed. For Sony, have the commands and KNX mappings confirmed for your model before activation.
  • Texts in DPT 16.001, such as the current Sonos track, are limited to 14 bytes. Missing feedback means neither zero nor stopped.
