Denon Electronics HEOS CLI Control Spec

Summary

The Denon HEOS is a network-connected, wireless, multi-room music system. This spec covers the HEOS Command Line Interface (CLI), accessed over a telnet (TCP) connection to port 1255 on a HEOS speaker. Commands are ASCII text strings of the form heos://command_group/command?attribute=value delimited by \r\n; responses are JSON. The CLI supports player transport control, volume/mute, queue management, multi-player grouping, browsing of local and online music sources, and unsolicited change events.

Transport

protocols:
  - tcp
addressing:
  port: 1255
auth:
  type: none  # inferred: no CLI connection auth procedure in source. Optional HEOS account sign_in exists for music-service access (see sign_in action).

Traits

traits:
  - queryable  # inferred: numerous get_ query commands in source
  - levelable  # inferred: set_volume / volume_up / volume_down commands in source
  - routable   # inferred: play_input routes source inputs to destination players; set_group groups players

Actions

# Command delimiter: \r\n. Special chars &, =, % in attribute values must be
# percent-encoded (%26, %3D, %25). Responses are JSON; some browse/search return
# a "command under process" intermediate response.

Macros

# Recommended driver initialization sequence from source (section 2.1.1):
# 1. register_for_change_events?enable=off
# 2. sign_in (if user credentials available)
# 3. retrieve status: get_players, get_music_sources, get_groups, get_queue,
#    get_now_playing_media, get_volume, get_play_state
# 4. register_for_change_events?enable=on

Safety

confirmation_required_for: []
interlocks: []
# Source documents no safety interlocks. reboot command affects only the
# connected speaker. No power-sequencing requirements stated.
# UNRESOLVED: no safety/interlock procedures in source.

Notes

• Discovery: HEOS products are discovered via UPnP SSDP; M-SEARCH search target (ST) is urn:schemas-denon-com:device:ACT-Denon:1. Once IP is known, open telnet to port 1255.
• A controller should connect to ONE speaker to control the whole HEOS ecosystem; do not connect to every speaker. Max 32 simultaneous socket connections per speaker. Typical pattern: one socket for change events, one for user actions.
• On first connection the CLI core spawns and needs time to discover players; expect a spew of events initially. Follow the initialization macro above.
• Command and JSON response delimiter is \r\n. Special characters &, =, % in attribute values are percent-encoded (%26, %3D, %%25); responses are similarly encoded and may need decoding for display.
• Browse/search responses may be deferred: a { "result": "success", "message": "command under process" } intermediate response is sent while CLI fetches from a remote server/service.
• Custom argument SEQUENCE=<number> may be added to browse commands to correlate request/response.
• Error responses: { "heos": { "result": "fail", "message": "eid=<id>&text=<text>&<command_args>" } }. Documented error codes: 1 unrecognized command, 2 invalid id, 3 wrong number of arguments, 4 data not available, 5 resource not available, 6 invalid credentials, 7 command not executed, 8 user not logged in, 9 parameter out of range, 10 user not found, 11 internal error, 12 system error (with syserrno), 13 processing previous command, 14 media can't be played, 15 option not supported, 16 too many commands in queue, 17 reached skip limit.
• Changes made to the HEOS account via the HEOS app are not reflected in CLI until the controller re-signs-in; provide sign-out/sign-in in the UI.
• QuickSelect commands (set/play/get_quickselects) apply only to LS AVR products (LEGO AVR, HEOS BAR).
• Supported online music services and their CLI browse/search capabilities are listed in source section 1.1; not all services support all transport controls.

summary: "All 60 spec actions are confirmed by verbatim command strings in the source; transport port 1255 and TCP protocol explicitly stated; the spec covers all source command groups completely. (5 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware version compatibility not stated in source. Physical/electrical specs not in source."
- "no safety/interlock procedures in source."
- "firmware version compatibility not stated in source."
- "physical/electrical specs not in source."
- "default/max records per browse response depends on service type (50 or 100) — not enumerated per service."
