Denon AVR Control

Use this skill to control a Denon receiver on the local network.

Quick start

1. Identify the receiver host or IP address.
2. Start with a read/query action before making changes.
3. Use scripts/denon_avr.py for normal operations.
4. If a model-specific command is missing, read references/commands.md and use --raw.

Default workflow

Query status

Run:

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --status

Power

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --power on
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --power off

Volume

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --volume 35.5
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --volume-up 3
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --volume-down 2

Inputs

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --input tv
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --input game
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --input heos

Mute

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --mute on
python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --mute off

Transport choice

Prefer the default TCP transport first:

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --status

If the receiver only responds on the HTTP control endpoint:

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --transport http --status

Raw commands

Use raw mode for model-specific features or when the canned arguments are not enough:

python3 skills/denon-avr-control/scripts/denon_avr.py --host <ip-or-hostname> --raw PW? --raw MV? --raw SI?

Read references/commands.md for the common command families.

Local computer playback

If the user wants to play local audio files on the computer itself, use scripts/local_audio_jukebox.py together with this receiver-control skill.

Read references/local-playback.md when the task is to:

• scan a local directory for songs
• play a random song or a short random queue
• play tracks that match a user query
• build a simple playlist from user-provided terms
• stop or inspect the local player state

This workflow plays audio on the local computer, so that machine's system output must already be routed to the receiver if sound should come out of the receiver.

Experimental DLNA push mode

If the user wants the Denon itself to fetch and play a local file over the LAN, use scripts/dlna_push.py.

Read references/dlna-push.md when the task is to:

• scan a folder for audio files before choosing one
• push a random local track directly to the Denon renderer
• push a track chosen by user query
• push a specific file path to the Denon
• stop the remote playback and shut down the temporary HTTP server
• support the same approach on Windows and macOS

This mode is more cross-platform than local-output playback because it uses Python + HTTP + UPnP/DLNA. It is still experimental and currently strongest for single-track push.

Real DLNA media server mode

If ad-hoc URL push is unreliable on a receiver, use scripts/simple_dlna_server.py instead.

Read references/dlna-server.md when the task is to:

• expose one or more user-chosen music directories as a real discoverable DLNA MediaServer
• let the user decide the music path(s) instead of assuming a fixed folder
• let the Denon browse the library through its Local Music / HEOS path
• support a more Windows-friendly and standards-based setup
• avoid raw one-off URL playback hacks

This mode provides SSDP discovery, a device description, a ContentDirectory service, a ConnectionManager service, and direct HTTP media serving.

Prefer this mode for cross-platform local-library playback.

Guardrails

• Query first when you do not know current state.
• Send one mutating action at a time unless the user explicitly wants a batch.
• Treat input names and sound modes as model-dependent; if a friendly alias fails, switch to --raw.
• If the user did not provide the receiver address, ask for the IP/hostname or discover it only if they explicitly want network scanning.
