Entities and Polling

Entities and Polling

Which SSC path feeds which Home Assistant entity, and how often it is read. Types, ranges and whether a path can be written: SSC Paths in the Neumann KH SSC Reference.

Source marks: see the legend on Home. Everything on this page is [code] unless marked otherwise.

Poll rates: fast = every cycle (30 s); fast, while enabled = every cycle, but only while an entity that reads the path is enabled (otherwise not polled; the first refresh after setup reads it once); slow = every 10th cycle (5 min), cached in between; setup = read once when the entry is set up; none = never polled.

Identity

Path	Poll	Entity / use
device/identity/product	setup	device model
device/identity/vendor	setup (config flow)	device manufacturer, Neumann check
device/identity/serial	setup	config entry unique ID
device/identity/version	setup	firmware version (device info)
device/identity/hw_version	slow	sensor Hardware version

Standby

Path	Poll	Entity
device/standby/enabled	fast	KH 120 II: switch Auto standby; KH 750: binary sensor Auto standby (the KH 750 follows its rear switch and refuses writes [measured])
device/standby/auto_standby_time	fast	number Auto standby time
device/standby/level	fast	number Standby threshold level
device/standby/countdown	fast, while enabled	sensor Standby countdown (disabled by default)

Outputs and inputs

Path	Poll	Entity
audio/out/level	fast	number Output level (step 0.5)
audio/out/delay	fast	number Delay
audio/out/mute	fast	switch Mute
audio/out/phaseinversion	fast (non-subwoofer models)	switch Phase invert (non-subwoofer models)
audio/out/label	slow	sensor Output label
audio/out5/level, audio/out5/mute	fast, only when detected	same entities as audio/out/level and audio/out/mute (see Integration-Behaviour)
audio/out1/level, audio/out2/level	fast, while enabled	numbers Output 1 level, Output 2 level (disabled by default)
audio/out1/delay, audio/out2/delay	fast, while enabled	numbers Output 1 delay, Output 2 delay (disabled by default)
audio/out1/mute, audio/out2/mute	fast, while enabled	switches Output 1 mute, Output 2 mute (disabled by default)
audio/out1/label, audio/out2/label	slow	sensors Output 1 label, Output 2 label (disabled by default)
audio/out1/loudspeaker, audio/out2/loudspeaker	slow	sensors Output 1 loudspeaker, Output 2 loudspeaker (disabled by default)
audio/in/interface	slow	select Input interface
audio/in/current_input	slow	sensor Current input
audio/digital_bypass	slow	binary sensor Digital bypass

On the KH 750, "Output 1" and "Output 2" are the output sockets A and B [measured].

Front and rear panel (ui/*)

All except ui/logo/brightness are read-only sensors: the speakers refuse writes to them [measured]. Logo brightness is a writable number and part of the backup restore [code].

Path	Poll	Entity
ui/logo/brightness	fast	number Logo brightness (not polled on the KH 750)
ui/input_gain	slow	sensor Input gain
ui/input_select	slow	sensor Input select
ui/bass_gain, ui/mid_gain, ui/treble_gain	slow	sensors Bass gain, Mid gain, Treble gain
ui/output_level	slow	sensor Output level (SPL)
ui/control_mode	fast	sensor Control mode (diagnostic)
ui/bass_management	slow	sensor Bass management
ui/channel_b_input_mode	slow	sensor Channel B input mode
ui/subwoofer_input_gain	slow	sensor Subwoofer input gain
ui/subwoofer_low_cut	slow	sensor Subwoofer low cut
ui/subwoofer_output_level	slow	sensor Subwoofer output level
ui/subwoofer_phase	slow	sensor Subwoofer phase
ui/subwoofer_phase_inversion	slow	sensor Subwoofer phase inversion

ui/auto_standby is not used.

Device

Path	Poll	Entity
device/name	slow	text Device name (disabled by default)
device/identification/visual	fast	switch Identify
device/restore	none	button Restore factory defaults (disabled by default; second press 2–30 s after the first)
device/save_settings	none	no entity; sent to the KH 80 only (see Integration-Behaviour)
device/temperature	fast	sensor Device temperature (shown in °C)

Meters and warnings

Path	Poll	Entity
m/in/level	fast	sensor Input level (live)
m/in/clip	fast	binary sensor Input clipping (on if any channel clips)
m/out/level	fast, while enabled	sensor Output level (live) (disabled by default)
m/out/clip	fast, while enabled	binary sensor Output clipping (disabled by default)
warnings	fast	binary sensor Warning (on for anything other than NO_WARNING)

Meters and the standby countdown are left out of backups.

EQ

Leaf	Poll	Entity
enabled	slow	switch {container} enabled (writes the whole array; on if any band is on)
gain, boost	none	set to 0 by button {container}: reset to flat
frequency, q, type	none	– (backup only)

The crossover eq1/in1|in2 of the KH 750 is not used. Details: Integration-Behaviour.
