Connectivity and compatibility15

Connectivity — what it means The wireless link or network the device uses. Wi-Fi connects straight to the router; Zigbee, Thread and Bluetooth Mesh work through a hub or gateway.	ZigbeeZigbee 3.0 (EFR32MG21 chip). Per the manual, only Zigbee devices of the SONOFF and eWeLink ecosystems can be added; the product page also mentions some third-party Zigbee devices — SONOFF keeps the current list [4] [1]
Connection to the router — what it means How the hub connects to the home network: over Wi-Fi it can sit anywhere within coverage; over an Ethernet cable the link does not depend on Wi-Fi quality.	Wi-Fi, Ethernet (cable)2.4 GHz Wi-Fi or an RJ45 10/100 Mbps port [1]
Matter role — what it means How the server works with Matter. A bridge exposes its connected devices to Apple Home, Google Home or Alexa; a controller adds Matter devices itself; a Thread border router links Thread devices to the home network.	Bridge, ControllerBridge: SONOFF/eWeLink Zigbee devices are passed on to Apple Home, Google Home, Alexa and SmartThings; a Matter controller (e.g. HomePod, Apple TV, a Google or Amazon hub) on the same LAN is required. Controller: per the product page, the gateway adds other makers' Matter devices to the eWeLink app. The specifications list no Thread radio, so no Thread border router role is stated [2]
Max connected devices — what it means How many devices can run on this coordinator's network according to the manufacturer. If the figure is for direct connections and the network grows through routers, this is noted.	256Up to 256 Zigbee devices in total (end devices and routers), of which up to 32 end devices directly on the gateway; the rest connect through Zigbee routers [2]
Works with ecosystems — what it means Which systems besides the maker's app can control the hub's devices, according to the manufacturer. The method (Matter, HomeKit, a voice assistant skill) is in the note; this usually needs an internet connection.	Apple Home, Google Home, Amazon Alexa, SmartThingsThrough the Matter bridge (a Matter controller on the same network is required). Alexa and Google Home are also available through the eWeLink cloud integration; IFTTT is supported [1]
Works without internet — what it means Whether the device keeps working over the local network or through a hub when the internet is down. Cloud features (remote access, voice assistants) need the internet.	YesBasic local Zigbee automation and device control work without internet; internet is needed for remote access, firmware updates and cloud scenes. Devices passed through the Matter bridge stay controllable on the LAN [3]
Home Assistant — what it means How the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration.	Via a separate integrationThe gateway's Zigbee devices sync to Home Assistant through an MQTT broker (set up by the user); connection via Matter is also possible [2]
App — what it means The maker’s app used to set up and control the device.	eWeLinkA local web interface is also available for adding devices to Matter without the app [1]
Wi-Fi bands — what it means Which router bands the module connects to. If only 2.4 GHz is supported, a 2.4 GHz network must be enabled on the router.	2.4 GHz [1]
Wireless range — what it means The stated radio range, usually in open space. Walls and floors cut it noticeably.	100 mZigbee: 100 m in open outdoor space at default power, 200 m in Turbo mode; indoors about 10 m through walls [2]
Processor / radio chip — what it means The microcontroller or radio module inside, per the maker (for example ESP32). For firmware such as WLED and ESPHome it determines available features and whether the device can be re-flashed.	RV1109 + EFR32MG21Dual-core 1.5 GHz CPU, 1 GB DDR4, 8 GB eMMC [1]
RAM — what it means The amount of RAM per the maker. The firmware uses it for the connection table and features such as VPN and parental control; with many devices, spare memory affects stability.	1 GB DDR4 [2]
Storage	8 GB eMMC [2]
Ethernet speed — what it means Maximum speed of the wired network port. 100 Mbps is enough for smart-home control; 1000 Mbps makes a difference for backups and video.	100 MbpsRJ45 10/100 Mbps port [1]
Radio frequencies and transmit power	Wi-Fi 2412–2472 MHz, Zigbee 2405–2480 MHz, BLE 2402–2480 MHzEU bands per the manual; Wi-Fi ≤ 20 dBm, Zigbee and BLE ≤ 10 dBm. BLE appears only in the radio data, not as a device protocol [3]

Power3

Power source — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	USBUSB Type-C connector, 5 V ⎓ 1 A. The manufacturer does not state whether an adapter is included [1]
Supply voltage — what it means The supply voltage (and current, if stated) as the maker gives it. It must match your mains or adapter.	5 V ⎓ 1 A (USB Type-C)DC power supply per EN 62368-1 (PS2 and ES1 classes) [1]
Power connector	USB Type-C [1]

Housing and installation5

Mounting — what it means How and where it is installed: in a wall box, on a wall or ceiling, on a DIN rail, on a table or in a socket.	Not stated by the manufacturer
Dimensions — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	82 × 82 × 28 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	92.5 gWithout accessories [1]
Housing material	PC + ABS [1]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE, FCC, ISED, RoHSSafety standard EN 62368-1 [1]

Model and version1

Colour — what it means The housing colour of this model. Other colours in the same series are separate products.	White [1]

Operating conditions3

Operating temperature — what it means The air temperature range the device is rated for. The lower limit matters outdoors, on balconies and in unheated rooms.	−10…40 °C [1]
Operating humidity — what it means The rated relative humidity range, non-condensing.	5–95%Non-condensing [1]
Operating altitude	below 5000 m [1]

Delivery, payment and returns

In your home

A reliable connection underpins your smart home.

A fast broadband plan does not fix weak signal through a wall. Several apps do not become one system by themselves. Placement and verified connections matter.

What to check before buying

We clarify the floor area and number of levels, where the provider’s router sits, which rooms matter for work and video, and whether cable can be run. Real speed also depends on your internet plan and the device itself.
Power — USB: plan it for the mounting spot.
