Connectivity and compatibility9

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); also acts as a Zigbee router (repeater) [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 gateway is required: SONOFF ZBBridge-P/-U, NSPanel Pro, iHost, SONOFF dongles or third-party Zigbee 3.0 hubs (Amazon Echo with Zigbee, SmartThings v3) [2]
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 hubVia a SONOFF Matter bridge: ZBBridge-U, iHost or Cube OS with a SONOFF Zigbee dongle [2]
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.	YesZigbee commands are handled by the local gateway or coordinator; the maker states local control via Home Assistant (e.g. direct binding with the SNZB-01M button). Cloud eWeLink features (voice assistants) need internet [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 ZHA or Zigbee2MQTT with a Zigbee coordinator (SONOFF Dongle Plus MG24, Dongle Lite MG21, Dongle Max, ZBDongle-P/-E) [3]
App — what it means The maker’s app used to set up and control the device.	eWeLink [1]
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 EFR32MG21Documents state “EFR32MG21” [1]
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.	10 dBmUp to 10 dBm (EU) [1]

Control and features6

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.	1One relay output with NO / COM / NC contacts [1]
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 buttonS1/S2 inputs. Default is rocker; switch to momentary by pressing the module button three times. In eWeLink the external trigger modes are pulse, edge and following [1]
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 among the model's specifications or features [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 in eWeLink: the external switch is decoupled from the relay and becomes a scene trigger. Supported with SONOFF gateways, ZHA and Zigbee2MQTT; not with Amazon Echo [3]
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.	Pulse / auto-off timer (inching)Inching: auto-off or auto-on after 0.5 s – 23 h 59 min 59.5 s (eWeLink and Zigbee2MQTT; not in ZHA or with Amazon Echo). Single channel, so no interlock [3]
Power-on state after outage	On / off / last state / reverse of last state; delay 0.5 s – 59 min 59.5 s (in eWeLink) [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.	RequiredOn mains power both L and N are needed. Instead of mains the module can be fed 12–48 V DC (DC+ / DC− terminals); AC and DC must not be connected at the same time [1]
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 boxInstalls in a mounting box; 41 × 43 × 21.5 mm [1]
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.	41 × 43 × 21.5 mm [1]
Weight — what it means The device’s weight without packaging, per the maker.	34.5 g [2]
Recommended wire gauge	18–14 AWG (0.75–1.5 mm²) [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]
Disconnection type	Type 1.B [3]

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.	2 A24 V ⎓ 2 A resistive; for 12/24 V ⎓ motors and valves up to 8 W. The output is for dry-contact and DC loads only — AC loads must not be connected; a 3 A overcurrent protection device is mandatory in the output circuit [2]
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.	YesVolt-free NO / COM / NC output (normally open and normally closed) [1]
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.	2 ASingle output: 24 V ⎓ 2 A resistive [2]
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, Low-voltage DCEither 100–240 V~ mains or 12–48 V ⎓; not both at once [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~, 50/60 Hz (0.1 A max) or 12–48 V ⎓ (1 A max)The site's description text says “110–240V AC”; the spec table and manual say 100–240 V~ [1]
DC load	24 V ⎓ 2 A (resistive) or 12/24 V ⎓ 8 W (motors, solenoid valves) [1]
Relay life	20 00020,000 automatic action cycles [1]
Rated impulse voltage	4000 V4 kV [3]
Output circuit protection	A 3 A overcurrent protection device is required in the output circuit [1]
