Denon HEOS speakers and soundbars integrate with Home Assistant for multi-room audio control. HEOS devices are discovered on your local network and provide playback control, speaker grouping, and media source selection.
HEOS speakers can be grouped with each other for synchronized whole-home audio, and Home Assistant can manage these groups through automations. The integration also exposes HEOS-capable Denon/Marantz receivers, bridging their zone management into the HEOS multi-room system.
Getting Denon HEOS connected to Home Assistant and running reliably.
Home Assistant discovers Denon HEOS media devices on your network automatically. Add them to see playback controls, volume, source selection, and grouping options.
Group Denon HEOS speakers with devices from other brands for synchronized whole-home audio. Control each room independently or as zones.
Build automations that play specific audio based on events — doorbell rings, morning alarms, or custom announcements. Route different media to different rooms.
The problems installers run into with Denon HEOS and Home Assistant — and how a managed setup prevents them.
Grouping HEOS speakers takes 3-5 seconds. Automations that group speakers and immediately start playback will fail without proper timing delays.
Accessing streaming services through HEOS requires a HEOS account linked to the service. Without this, Home Assistant can only play local media or use the speaker for TTS.
HEOS uses SSDP for discovery, which doesn't cross VLAN boundaries. Speakers on a different network segment than Home Assistant won't be discovered.
