Connectivity and compatibility11

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 (IEEE 802.15.4) [1]
Hub required — what it means Whether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise.	Hub (gateway) requiredA Zigbee 3.0 gateway is required. SONOFF recommends ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost; also ZBDongle-P/-E. Philips and FRITZ!Box gateways are not supported [1]
Matter support — what it means Whether the device supports the Matter standard, directly or through a bridge. Matter lets you add it to Apple Home, Google Home, Alexa and Home Assistant.	Via the maker's bridge hubNo native Matter. The maker describes adding it to Apple Home through a Matter bridge: ZBBridge-U or the eWeLink CUBE software [3]
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.	YesThe maker lists Home Assistant via ZHA and Zigbee2MQTT with a SONOFF USB adapter, which is local control without the cloud. There is no separate statement for this model about offline use through eWeLink gateways [2]
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 Zigbee coordinator or hubVia a Zigbee coordinator: ZHA or Zigbee2MQTT with SONOFF adapters (ZBDongle-P/-E, Dongle Max, Dongle Plus MG24, Dongle Lite MG21); on/off, switch mode, detach relay, OTA [2]
App — what it means The maker’s app used to set up and control the device.	eWeLink (through a SONOFF Zigbee gateway)Through a SONOFF Zigbee gateway; via the eWeLink cloud — Alexa, Google Home, IFTTT [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.	Silicon Labs EFR32MG22 [1]
Compatible gateways	eWeLink: ZBBridge-P, ZBBridge-U, NSPanel Pro, iHost. Home Assistant (ZHA / Zigbee2MQTT): ZBDongle-P/-E, Dongle Max, Dongle Plus MG24, Dongle Lite MG21. Not supported: Philips gateways and FRITZ!Box Zigbee routers.If the module will not pair, update the gateway to the latest firmware [2]
Radio frequencies and transmit power	Zigbee: 2405–2480 MHz [1]
Transmit power — what it means The coordinator's maximum radio output. Higher power gives a steadier link to distant devices, but range in a home depends more on walls and the number of routers in the network.	Zigbee ≤ 10 dBm [1]
Cloud integrations via eWeLink	Amazon Alexa, Google Home, IFTTT [2]

Control and features7

Channels (relays) — what it means How many independent loads the module switches: 1 — one light circuit or appliance, 2 — two circuits (e.g. chandelier and accent lights), 4 — a panel unit for several circuits.	2Two independent outputs L1 and L2 and two switch inputs S1, S2 [2]
Wired wall switch input — what it means Whether you can keep an ordinary wall switch or push button and wire it to the module, so the light works from both the switch and the app. Shows which switch types are supported; on dimmers a momentary button usually also adjusts brightness when held.	Rocker switch (latching), momentary push buttonInputs S1 and S2; the product page lists rocker, momentary and SPDT (two-way) switches; rocker by default, changed by pressing the module button three times [3]
Energy metering — what it means Whether the switch shows in the app how much the connected appliance uses: live power and accumulated kWh.	NoEnergy metering is not listed in the specifications or feature list [2]
Detached key mode (scene button) — what it means The switch wired to the module can be decoupled from the relay: the load stays powered and a press runs a scene. Needed when the circuit has smart bulbs.	YesDetach Relay mode; per the maker’s table it is available in eWeLink and in Home Assistant (ZHA, Zigbee2MQTT) [2]
Special relay modes — what it means Modes beyond on/off. Pulse: the relay switches itself off after a set time (bell, lock, gate). Interlock stops two channels being on at once. Motor mode drives curtains or a gate: up, down, stop.	Not stated by the manufacturer
External switch modes	Pulse, Edge, FollowingSet in the eWeLink app; the switch type (rocker / push button) is changed by pressing the module button three times [2]
Stepper function (step-through scenes from one switch)	YesOne external switch cycles through load combinations set in the app; works with rocker switches and push buttons; disabled while detach relay is on. Up-to-date firmware may be needed [3]

Housing and installation8

Neutral wire (N) — what it means Whether the wall box needs a neutral wire. Older wiring often brings only the live wire to the switch; then pick a model that works without N.	Not requiredWorks without a neutral and with no bypass at the lamp: terminals L, L1, L2, S1, S2; there is no N terminal. Minimum load 3 W [2]
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.	In a wall boxIn a standard mounting box behind the switch; per the product page it also fits European 60 mm boxes [2]
Dimensions (W × H × D) — what it means The device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf.	45 × 39.4 × 16.8 mmDepth for the wall box: 16.8 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	33 gNet [1]
Recommended wire gauge	16–14 AWG (≈1.3–2.1 mm²), copper conductor only, solid or strandedDocuments state “16AWG to 14AWG SOL/STR copper conductor only”; the mm² figure is an approximate conversion [1]
Recommended circuit breaker	12 AAn 12 A MCB or RCBO must be installed ahead of the module. Single-phase use only [1]
Housing material	Polycarbonate (PC) [1]
Certifications — what it means Standards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter).	CE, FCC, RoHS [1]

Power and load9

Max current per channel — what it means Highest current through one relay with a resistive load. 10 A at 230 V is about 2,300 W of heater or incandescent lamps; for LEDs and motors the permitted load is lower.	8 A8 A per channel, both channels together no more than 12 A; resistive load, 100–240 V ~ [1]
Dry contact (volt-free output) — what it means The relay only opens or closes its contacts without putting voltage on them. This is how boilers, gates, barriers and other devices with a control input are connected.	NoOutputs L1 and L2 are live (100–240 V ~), not volt-free contacts [2]
Max total current — what it means Current the device handles across all channels at once. On multi-channel models the total is often lower than per-channel current × number of channels.	12 ABoth channels together, resistive load [1]
Max power per channel (resistive) — what it means Power of incandescent lamps, heaters and other resistive loads per channel at 220–240 V. For LEDs, motors and power supplies the permitted power is lower.	Not stated by the manufacturer
LED load per channel — what it means Total LED lamp wattage per channel that the maker allows. Add up the watts of all lamps on that circuit and compare; for dimmers only dimmable lamps count. If the maker gives the figure in VA or as a total for all channels, the note says so.	300 WAt 240 V; 150 W per channel at 100 V. Both channels together: 600 W at 240 V, 300 W at 100 V [1]
Minimum load — what it means The lowest lamp wattage on the circuit at which the device works reliably. It matters for no-neutral wiring and for dimmers with LED lamps: below it, lights may flicker or glow faintly when off.	3 WFor no-neutral operation. Maker: no anti-flicker module is needed, and connecting one may damage the device [1]
Module power supply — what it means Where the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery.	AC mains [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.	100–240 V AC, 50/60 Hz [1]
Supported load types	Incandescent, LED, halogen (except MLV low-voltage) and compact fluorescent (CFL) lampsLamp types are from the help-centre FAQ; the official spec image adds that lamp power must exceed 3 W and smart bulbs and inductive loads (e.g. fans) are not supported [4]

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 conditions2

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]
