Connectivity — what it meansThe 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. | Wi-FiWi-Fi IEEE 802.11 b/g/n, 2.4 GHz only. Bluetooth must be on on the phone when adding it in eWeLink. The module also receives eWeLink-Remote signals (R5, S-MATE) [1] |
|---|---|
Hub required — what it meansWhether the device needs a separate hub, gateway or coordinator to work in a smart home. If so, it is sold separately unless stated otherwise. | No hub neededMaker: “No hub is required” — the module connects straight to the home Wi-Fi [1] |
Matter support — what it meansWhether 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 built-in Matter (the Matter version is the separate MINIR4M model). The maker describes adding non-Matter SONOFF Wi-Fi devices to Apple Home and other systems through a Matter bridge: the eWeLink CUBE software or the ZBBridge-U, iHost and NSPanel Pro hubs. This is a general description; MINIR4 is not named in it [2] |
Works without internet — what it meansWhether 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. | YesLAN Control mode: the eWeLink app controls the module directly through the router, without the cloud (on/off). eWeLink-Remote remotes (R5, S-MATE) control it locally [1] |
Home Assistant — what it meansHow the device connects to Home Assistant: a built-in integration, a Zigbee coordinator, Matter or the maker’s cloud integration. | Via the maker's integrationThe maker's official “Add to Home Assistant” illustration shows the module in Home Assistant via the eWeLink Smart Home section. The maker also describes access through the eWeLink CUBE Matter bridge [3] |
App — what it meansThe maker’s app used to set up and control the device. | eWeLinkAlexa, Google Home, IFTTT, SmartThings and Alice link through the eWeLink cloud [1] |
Processor / radio chip — what it meansThe 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. | Espressif ESP32-D0WD-V3, dual-core [1] |
| Wi-Fi | IEEE 802.11 b/g/n, 2.4 GHz [1] |
| Third-party platforms (via eWeLink) | Alexa, Google Home, IFTTT, SmartThings, Alice [1] |
Channels (relays) — what it meansHow 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 L Out output [1] |
|---|---|
Wired wall switch input — what it meansWhether 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: momentary, door exit, SPDT and latching switches and dry-contact sensors. Input modes: Pulse / Edge / Following. Cable to the switch up to 20 m [1] |
Energy metering — what it meansWhether the switch shows in the app how much the connected appliance uses: live power and accumulated kWh. | NoNo consumption metering in the specifications or the eWeLink feature list [1] |
Detached key mode (scene button) — what it meansThe 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 is enabled in eWeLink (“Switch Mode”): pressing the external switch does not change the relay state and can trigger a scene. MINIR4 is in the official list of devices with this feature [1] |
Special relay modes — what it meansModes 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 mode in eWeLink: automatic off or on after 0.5 s – 23 h 59 min 59.5 s. Single-channel model — no interlock or motor mode [1] |
| eWeLink-Remote gateway | YesPairs eWeLink-Remote remotes and switches (R5, S-MATE) as sub-devices for local control; the app screen in the manual shows up to 8 sub-devices [4] |
| External switch modes | Pulse / Edge / Following (in eWeLink) [1] |
| Power-on state after outage | On / off / last state / reverse of last state; power-on delay 0.5 s – 59 min 59.5 s (in eWeLink) [1] |
| Relay endurance (automatic operations) | 10 000“Automatic action: 10000 Cycles”; control type 1.B, rated impulse voltage 4 kV, pollution degree II [1] |
Neutral wire (N) — what it meansWhether 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. | RequiredTerminals N (in and out), L In, L Out; per the wiring diagram the neutral is connected to the module [1] |
|---|---|
Mounting — what it meansHow 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 boxFits entirely into the wall box behind the switch; the maker names the smallest European boxes and 86-type boxes. No part of the module may remain exposed after installation [1] |
Dimensions (W × H × D) — what it meansThe device’s size in millimetres as the maker states it. Check that it fits the wall box, niche or shelf. | 39.5 × 33 × 16.8 mmWidth × height × depth per the maker's drawing [1] |
| Cable length to the external switch | 20 mMaximum, per the troubleshooting section [1] |
Weight — what it meansThe device’s weight without packaging, per the maker. | 26.7 gNet [1] |
| Housing material | PC V0 (flame-retardant polycarbonate) [1] |
Certifications — what it meansStandards and certifications the maker lists for this model (for example CE, RoHS, Zigbee 3.0, Matter). | CE, FCC, RoHS, SRRC, TÜV, ISEDStandard: EN IEC 60669-2-1 [1] |
| Recommended wire gauge | 16–14 AWG (≈1.3–2.1 mm²), copper only, solid or strandedDocuments: “16AWG to 14AWG SOL/STR copper conductor only”; the mm² conversion is for reference [1] |
| Recommended circuit breaker | 10 AAn MCB or RCBO rated 10 A upstream of the module [1] |
Max current per channel — what it meansHighest 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. | 10 AResistive load, 100–240 V [1] |
|---|---|
Dry contact (volt-free output) — what it meansThe 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. | NoThe L Out terminal is a switched 100–240 V live output, not a volt-free contact. The maker allows dry-contact sensors only on the S1/S2 inputs, as an external switch [1] |
Max total current — what it meansCurrent the device handles across all channels at once. On multi-channel models the total is often lower than per-channel current × number of channels. | 10 ASingle-channel model: same as the channel current [1] |
Max power per channel (resistive) — what it meansPower 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. | 2400 WAt 240 V, resistive load [1] |
LED load per channel — what it meansTotal 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. | Not stated by the manufacturer |
Module power supply — what it meansWhere the device gets its power: 230 V mains, an adapter, USB, batteries or a built-in battery. | AC mains [1] |
Supply voltage — what it meansThe 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] |
Colour — what it meansThe housing colour of this model. Other colours in the same series are separate products. | White [1] |
|---|
Operating temperature — what it meansThe 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 meansThe rated relative humidity range, non-condensing. | 5–95%Non-condensing [1] |
| Operating altitude | 2000Below 2000 m [1] |
| Package contents | Module, quick guidePer the official package photo [5] |
