Denon is an audio brand founded in Japan in 1910 that makes AV receivers, Denon Home speakers, soundbars, amplifiers and network audio players. Products with HEOS Built-in are set up and controlled from the HEOS app, and receivers have a separate Denon AVR Remote app for basic functions. Wikipedia lists Sound United as the parent and Harman, owned by Samsung, as the owner since September 2025.
Denon is an audio and home-theatre brand rather than a smart home hub brand. HEOS Built-in products join the home network and are controlled through the HEOS app. Denon's pages describe AirPlay 2, Bluetooth, Alexa and Google Assistant voice control, and Siri on selected Denon Home speakers. We found no Matter, Zigbee, Z-Wave or Thread support on Denon's pages.
That suits people who want multi-room music and receiver control inside Alexa, Google, Apple or a home-automation system such as Home Assistant, Homey, Control4 or Crestron. It is weaker for broad smart home use: the voice integrations cover music, volume and (for receivers) power and input, and Home Assistant's HEOS page says that integration cannot control receiver functions such as power or zone selection.

The controller app for HEOS Built-in products from Denon, Marantz and Definitive Technology. It handles guided setup, multi-room grouping, music services, search and playback of local music. The App Store listing names D&M Holdings as the provider and does not mention Alexa or Google Home. Denon's buying guide says the free app is on the App Store and Google Play, but we could not open a Google Play page to confirm the listing.
Controls network-ready Denon AV receivers from 2014 onwards: power, volume, input and settings. On HEOS Built-in receivers it hands network browsing over to the HEOS app. The listing says Network Control must be switched on in the receiver. The App Store listing is from D&M Holdings. We could not confirm a Google Play listing.

HEOS is described by Denon as a wireless multi-room system, with music services reached over Wi-Fi. Home Assistant's HEOS page asks for the address of a wired, always-on HEOS device, and openHAB's HEOS binding also prefers a wired device as its bridge, so a network cable is recommended for reliability.
Denon's guide says HEOS Built-in products support AirPlay 2, and Denon's HEOS Built-in page says Siri on an Apple device can control playback and group rooms.
No Denon announcement or product found when we searched. Denon's HEOS Built-in page and HEOS guide do not mention Matter, and a May 2024 article on Siri for Denon speakers does not either.
Denon documents Alexa for HEOS Built-in speakers, receivers, soundbars and amplifiers. Setup is to enable the HEOS Home Entertainment skill in the Alexa app and discover devices. Commands cover playing from a music service, volume, mute and transport. For receivers and soundbars Alexa can also power on and off and switch HDMI inputs. An Echo or Dot is needed to control a receiver.
Denon says to start playback in the HEOS app and then use Google Assistant, or link the HEOS action in the Google Home app. Voice control covers volume, pause and skipping tracks, including in named rooms. The page lists the AVR-S760H and several archived models. Its intro mentions Amazon Alexa, which conflicts with the rest of the page.
A May 2024 AppleInsider report says select Denon Home speakers (150, 250, 350 and Home Soundbar 550) gained Siri control through a HomePod or HomePod mini, with Alexa switched off while Siri is used. The article does not say the speakers appear as HomeKit accessories, and we found no Apple Home page from Denon. AirPlay 2 is documented by Denon.
Denon was an early adopter of Control4's Simple Device Discovery Protocol and takes part in its driver certification program. A 2016 trade report describes Control4 HEOS drivers (v1.0.31) shipping with HEOS firmware, with Composer commands for favourites and playlists.
A 2014 Crestron press release says select Denon receivers (AVR-X3000, AVR-X4000 and AVR-4520CI, North America only) gained Crestron Connected over Ethernet. Crestron's application market also lists a Denon HEOS Device Interface module (v6.0) for single HEOS speakers, requiring a 3-Series processor.
A community-written Denon Network AV Receivers device handler exists, but its forum thread is titled withdrawn and a related topic is titled obsolete. The page does not say who withdrew it or name a replacement.
Two built-in integrations, neither maintained by Denon. Denon AVR Network Receivers controls receivers locally over the network (Local Push), with main-zone and zone 2 or 3 media players, source and sound-mode selection, and auto-discovery. Denon HEOS controls HEOS players and groups locally with real-time updates. Home Assistant's HEOS page says it cannot control receiver features such as power or zone selection and points to the Universal Media Player for combining the two. A community thread reports Denon Home speakers being detected by the AVR integration, with some Wi-Fi and standby problems.
The Denon HEOS app is published by Athom, the maker of Homey, and labelled Official on its store page. It controls HEOS speakers and AV receivers by starting favourites, changing volume and starting AUX-In in Flows. The page lists Homey Cloud, Pro, Pro mini and Self-Hosted Server, yet also shows Technology LAN with Homey Bridge required, and we could not resolve which applies. It is not published by Denon. We did not confirm a separate Homey app for non-HEOS Denon receivers.
Two bindings in openHAB's official add-on list, not maintained by Denon. The Denon / Marantz binding covers AV receivers over telnet (port 23, off by default) or HTTP, with mDNS discovery. The Denon HEOS binding uses a bridge over telnet on port 1255 and covers players, groups and favourites.
Community nodes exist. node-red-contrib-denon-sxp, maintained by an individual, talks to Denon AVRs over telnet port 23 with an in node for status and an out node for commands.
Sound United publishes a HEOS CLI Protocol Specification (version 1.10, November 2017, hosted copy). Control systems find devices by UPnP SSDP and open a telnet connection to port 1255. Commands are plain text and replies are JSON, covering grouping, volume, queue, browsing, playback and unsolicited change events. The document says it is for professional use and that no programming support is offered.
Home Assistant and openHAB control receivers locally over telnet and HTTP, and Denon's app listing says Network Control must be enabled. We did not open an official Denon page documenting the receiver protocol; a Node-RED page references a protocol PDF for the older AVR-3312.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
