eWeLink is an app and cloud platform from Shenzhen CoolKit Technology Co., Ltd. SONOFF devices are controlled with it, and the developer's App Store listing describes it as an app platform for multiple brands of smart devices. It is not a hub brand of its own: devices are added to an eWeLink account, and an optional local system called eWeLink CUBE can run on a Raspberry Pi, PC, NAS or Docker.
eWeLink works mainly through the CoolKit cloud and the eWeLink app, with LAN mode for some Wi-Fi devices and a local DIY mode API for a few SONOFF models. Zigbee, Matter bridging and local automation are handled by separate hardware or software such as CUBE (iHost), the Zigbee Bridge Ultra or the NSPanel Pro. Other platforms connect either through the cloud (Alexa, Google Home, SmartThings, IFTTT, Homey) or through CoolKit's Home Assistant add-on.
The platform suits households that already use SONOFF or other eWeLink-compatible devices and want one app, voice assistants and optional local control. It is weaker as a neutral hub: some of the more advanced features sit behind paid Advanced or Prime plans (prices not found), most third-party routes depend on the cloud, and Matter support is described on eWeLink's own pages as limited to specific device types and still being extended.

Remotes RF remote controllers and eWeLink-Remote sub-devices (R5, S-MATE)
The main app, published by Shenzhen CoolKit Technology. Remote control, scheduling, timers, smart scenes, device sharing, grouping and LAN mode. The App Store listing shows iPhone, Mac (Apple silicon), Apple Vision and Apple Watch support, version 5.30.0 when read. An Advanced Plan (paid) adds a web version and more, and eWeLink's forum describes a higher Prime Plan. The Google Play link uses the package name com.coolkit; we could not open the Google Play page itself to confirm it.
A separate CoolKit app for managing 2.4G Bluetooth and eWeLink-Remote devices, such as fans, heaters, fingerbots and lights. The App Store listing offers Bluetooth discovery, account login and timers. It is listed as iPhone-only (version 1.1.9 when read). We did not find an official Google Play page.
Web and tablet clients named on CoolKit pages. The V5.28 release post says the app scanner can sign in to eWeLink WEB and eWeLink CAST, and the Matter Q&A names CAST as a tablet app that can act as a hub. We did not find store links for CAST.

eWeLink app and account
Official
The eWeLink app is the main control point. Devices are paired to an eWeLink account and controlled locally (LAN mode) or through the cloud. The App Store lists remote control, schedules, timers, smart scenes, sharing and grouping.
The Developer Center describes integrating products into the CoolKit Cloud Service, with data centers and CDN acceleration, and states coverage of 170 countries and markets. A CSA article from August 2025 says 176 countries and 40 million users. The two pages give different country counts. No hosting or pricing terms were found for the cloud itself.
Described as a free, self-hosted local system that bridges eWeLink Wi-Fi and multi-brand Zigbee devices into Matter. Install options on the product page: Raspberry Pi, Windows, macOS (Apple Silicon and Intel), Docker, NAS (Synology, Ugreen) and virtual machines. The page states zero cloud dependency and lists Apple Home, Google Home, Alexa, SmartThings, Home Assistant and Homey.
CoolKit pages use the name iHost for the CUBE hub and list it, the NSPanel Pro and the Zigbee Bridge Ultra as bridges or hubs. The Matter Q&A names the NSPanel Pro and the eWeLink CAST app as hubs for Matter devices. Hardware specifications were not checked.
A network of one gateway and up to 8 sub-devices. Gateway-capable SONOFF devices include BASICR4, MINIR4, MINIR3, DUALR3, NSPanel Pro, M5 and iHost (firmware V1.11.0 and later). Sub-devices include R5/R5W and S-MATE.
Paid app plans exist. The App Store listing says the Advanced Plan adds a web version and more. A forum post of 12 November 2025 says Prime includes everything in Advanced plus Wear OS support, higher sharing and virtual device limits, and later an MCP server. A release post of 21 August 2026 describes a Prime trial. Prices were not stated on the pages we read.
Lets the phone control some Wi-Fi devices over the local network without the cloud when both are on the same Wi-Fi. The page we read is dated to about 2021-2022 (app V4.11) and says schedules, scenes and sharing need internet for initial setup. Listed devices are 1-4 gang switches and sockets, dimmers, bulbs and POW switches. Not all routers are compatible.
Handled through a bridge or hub rather than the phone: CUBE works with Zigbee devices from 100+ brands using a Zigbee dongle, and the Zigbee Bridge Ultra is named for Zigbee sub-devices. CoolKit's CSA article says eWeLink adopted Zigbee in 2020.
The RF Bridge is named on a LAN page and SONOFF compares eWeLink-Remote with 433 MHz RF, giving about 100 m against about 15 m. eWeLink-Remote is described as a Bluetooth 2.4G link on a 433 MHz base, and the page text is not fully consistent on the radio. 868 MHz was not found on any page read.
No Z-Wave, Thread, infrared or KNX support was found on the eWeLink pages read. The Matter Q&A and Matter bridge page mention no Thread role. This is absence of evidence, not a statement that none exists.
The eWeLink app adds a limited set of Matter devices with app v5.6 and a hub (NSPanel Pro v3.1.0 or CAST app v2.1): lights, switches and plugs, window/door, temperature and humidity sensors and bridges. Bridges (CUBE/iHost, Zigbee Bridge Ultra) expose non-Matter devices to Apple, Google, Amazon and SmartThings. The CUBE bridge page calls the feature experimental and lists only on/off switches and plugs, with lights from CUBE V1.9.0. The Matter Q&A and bridge page are undated.
The eWeLink Smart Home skill is linked from the eWeLink app or the Alexa app. Supported types on the setup page are plugs and switches, lights and fans. The ecosystem page also mentions app-to-app linking and an energy dashboard.
The ecosystem page says eWeLink is an authorized smart home solution provider for Google Assistant, listing Request Sync, Report State, Local Control and App Flip linking.
Listed as an ecosystem where eWeLink devices work through account linking. LAN-enabled devices are also noted as usable with SmartThings on the LAN page. CUBE lists SmartThings as a Matter platform.
No direct HomeKit route is described on the page we read. Devices reach Apple Home through Matter, using a bridge (iHost or Zigbee Bridge Ultra) for non-Matter devices, or native Matter devices such as MINIR4M. It requires a HomePod or Apple TV home hub. The page is dated 23 August 2024. Homebridge is mentioned as a community option.
eWeLink is an IFTTT service with eWeLink devices as actions. The help article says the integration needs the Advanced plan. The article is undated and may predate current plans.
The App Store listing names smart scenes, schedules, timers, loop timers, inching and interlock. CUBE adds local automation. Sub-devices of eWeLink-Remote can trigger app scenes. The LAN page says scenes need internet for initial setup.
A developer console for integrating products into CoolKit's cloud, with a Docs Center and a list of supported voice assistants. API, OAuth and SDK details were not on the page fetched.
A local Web API under /open-api/V2/rest. Access needs a physical link-button press and a Bearer token. Reference examples cover add-ons, device lists and control, custom tiles, MQTT-to-HTTP bridging and a Node-RED palette. The developer contact is cube_developer@coolkit.cn.
SONOFF documents a local HTTP API for selected devices (BASICR3, RFR3, MINIR2, MINIR3, D1, SPM-Main and some LED bulbs). Discovery is mDNS service _ewelink._tcp, with HTTP on port 8081. Changing mode erases user settings and firmware updates then need the eWeLink app. Page last modified 2025-06-20.
A new eWeLink Smart Home add-on was announced on the Home Assistant community forum on 13 January 2026, said to replace the legacy add-on. It syncs devices over MQTT, prioritises LAN control with cloud fallback, and installs from an add-on repository. The legacy add-on is described as no longer maintained. The post's author could not be confirmed as CoolKit staff from the page.
The Home Assistant add-on routes are documented by CoolKit, not by Home Assistant. We could not open home-assistant.io integrations pages to confirm or rule out a built-in eWeLink or SONOFF integration, so this is unconfirmed.
