Navien equipment connects through NaviLink, an optional Wi-Fi add-on for many tankless water heaters, combi-boilers and boilers, with a single-unit NaviLink Lite version. Newer heat pump and air conditioning units use a built-in IoT module with Wi-Fi and Bluetooth. We found no voice assistant, Matter or hub-based ecosystem support from Navien itself.
That suits owners who want remote temperature control, usage data and error alerts from one app, and installers who want to monitor customer units. It is weaker for smart home automation: integrations with Home Assistant come from community projects, some of which use reverse-engineered protocols or add extra hardware.

The homeowner and installer app, published by KYUNGDONG NAVIEN CO., LTD. It shows status and energy use, adjusts temperatures and modes, sets heating, cooling and hot water schedules, and sends maintenance alerts. Installers can monitor customer units when homeowners grant access. The listing mentions boilers, water heaters, HVAC and water treatment equipment, thermostats and the NWP500. We could not verify a Google Play link: a package name, com.kdnavien.navilink, appears on a third-party site only.
Installer app named in the NAC-10SM manual. It uses Bluetooth for diagnostics and firmware updates on units with the IoT module. We found no store links.

| Wi-Fi (NaviLink) | Yes | NaviLink is an optional Wi-Fi control add-on for tankless water heaters, combi-boilers and boilers (NPE-2, NPN, NCB-H, NFC-H, NHB, NFB-H and NFB-C series). The NaviLink Lite version controls a single residential unit, draws power from the unit and works over Wi-Fi only. Navien says existing installations may need a new main PCB and front control panel. A 2016 press release introduced the original NaviLink Wi-Fi. | Navien NaviLink page Navien press release |
| IoT module (Wi-Fi and Bluetooth 5.0) | Yes | The NAC-10SM IoT module for NAZ heat pumps and NAE air conditioners connects over RS-485 to the unit and offers Bluetooth 5.0 and Wi-Fi on 2.4 GHz and 5 GHz. Homeowners pair it in the NaviLink app and installers use the Navien Multikit app over Bluetooth. | NAC-10SM manual |
| Wired NaviLink port (RS-485) | Community | Community ESPHome projects connect an ESP32 to the heater's NaviLink port over RS-485 and expose it to Home Assistant, with no Navien cloud involved.

It was archived by its author on 14 April 2023, who said Navien's newer protocol required a full refactor and pointed to the separate Home Assistant component. | PyNavienSmartControl |
