Neumann Connect Wiki

This wiki covers the Neumann Connect Home Assistant integration for Neumann KH DSP loudspeakers: how it talks to the speakers, which entities it creates, and how to solve typical problems. For installation see the repository README.

The device and protocol reference moved. What is known about the Sennheiser Sound Control protocol (SSC) and the speakers themselves - wire format, paths, standby, control mode, EQ, measured limits - now lives in the Neumann KH SSC Reference in the Neumann Control wiki. It applies to every SSC client, including this integration.
