Quick pick: If you don’t have time to read the full guide, the model that works best for most homes is the Sonoff MINIR4M — it fits behind virtually any existing wall switch, supports Matter, and costs under $15.
What Is a Sonoff Smart Switch and What Does It Do?
A Sonoff smart switch is a compact electronic module that installs behind your existing wall switch — or replaces it entirely — turning it into a device you can control from your phone, by voice, or through automated routines. You don’t need to replace your light bulbs or rewire your home: just place the module inside the electrical box and connect the wires as shown in the manual.
Sonoff is a brand by Chinese manufacturer ITEAD, which has been in the affordable smart home market for over a decade. Their products stand out for three specific reasons: accessible pricing (most models cost between $8 and $20), an easy-to-use companion app (eWeLink), and broad compatibility with all major smart home ecosystems — Amazon Alexa, Google Home, Apple Home, and Home Assistant.
Before You Buy: Three Questions to Answer First
Before choosing a specific model, answer these three questions. Your answers will determine exactly which switch you need.
1. Do You Have a Neutral Wire at Your Switch Box?
This is the single most important factor. The neutral wire (usually white in the US, blue in Europe) provides continuous power to the module so it can stay connected to your network even when the light is off. Most modern homes have it, but many properties built before the 1990s only have the live wire running to the switch.
To check: turn off the breaker, remove the switch plate, and look for a white (or blue) wire inside the box. If there is no neutral wire, you need a no-neutral model such as the ZBMINIL2 or the MINI DUO-L.
2. Which Protocol Do You Prefer: WiFi or Zigbee?
Sonoff switches work with two main protocols:
WiFi connects the device directly to your router. The advantage is that no additional hub is required. The downside is that each module uses a WiFi slot, and heavily loaded networks can become unstable. The most recent Sonoff WiFi models support Matter — the new universal standard that lets you control them from Apple Home, Google Home, and Alexa without relying on any cloud server.
Zigbee uses a separate mesh network that runs independently of your WiFi. It performs better in large homes because devices relay signals to one another, extending coverage automatically. The drawback is that you need a Zigbee hub (such as the Sonoff ZBBridge Pro or Sonoff iHost) to connect devices to the internet. If you already run Home Assistant, Zigbee modules integrate directly via the Sonoff USB dongle without any additional hub.
General rule: If you have one or two rooms and don’t use Home Assistant, go with WiFi. If you want to automate an entire home or already have a Zigbee network, go with Zigbee.
3. Do You Want to Hide the Module or Replace the Switch?
In-wall relay modules (the MINI, BASIC, and DUALR3 families) install inside the existing electrical box, hidden behind your current switch plate. The wall switch looks and feels exactly the same from the outside, and you keep full manual control in addition to smart features.
Smart wall switches (the TX, SwitchMan, and NSPanel families) fully replace your existing switch plate with a touch panel that has built-in WiFi. They are visible on the wall and change the appearance of the room.
In-Wall Relay Modules: Sonoff’s Best-Sellers
In-wall modules are the most popular choice because they can be installed without changing the look of your home. Here are the most relevant models from the current lineup.
Sonoff MINIR4M — The Best Choice for Most Homes
The MINIR4M is Sonoff’s first Matter-certified device and the model that makes the most sense to buy in 2026. It is a single-channel WiFi relay that fits inside virtually any standard electrical box, including the smallest 86-type and EU boxes.
Its standout feature is Matter compatibility: you can add it to Apple Home, Google Home, Amazon Alexa, or SmartThings simply by scanning the QR code included in the box — no need to open the eWeLink app first. Matter devices also work locally, meaning they keep responding even if your internet connection goes down.
It also includes a Detach Relay mode that is especially useful if you use smart bulbs: it allows the physical wall switch to send a signal without cutting power to the circuit, so the bulb never goes offline.
What you need to know: requires a neutral wire and only works on 2.4 GHz WiFi networks. Maximum load: 10A (2400W). Certified by TÜV, CE, and FCC.
Best for: any user who wants hassle-free smart home automation, especially those using Apple Home or multiple ecosystems simultaneously.

Sonoff ZBMINIL2 — The Best Zigbee Option Without a Neutral Wire
If your home doesn’t have a neutral wire at the switch box, the ZBMINIL2 is your solution. It is the smallest Zigbee module in Sonoff’s lineup — measuring just 39.5 x 32 x 18.4 mm — and is specifically designed for older installations where only the live wire reaches the switch.
It works with LED bulbs from as low as 3W, making it compatible with virtually all modern lighting without needing an anti-flicker module. Built on Zigbee 3.0, it integrates directly with Home Assistant (via ZHA or Zigbee2MQTT), Alexa, and Google Home.
One important detail: the ZBMINIL2 is a Zigbee End Device, which means it does not repeat or extend the network signal. If your Zigbee mesh is already solid, this is not a problem.
What you need to know: requires a Zigbee hub (sold separately). Maximum load: 6A.
Best for: older homes without a neutral wire that already have or plan to install a Zigbee network.

Sonoff ZBMINIR2 — Zigbee With Neutral Wire and Network Repeater (NEW 2025)
The ZBMINIR2 is the most advanced member of the MINI Extreme Zigbee family. Unlike the ZBMINIL2, this model requires a neutral wire, but in return it delivers significantly more powerful features.
The key difference is that it functions as a Zigbee router: it amplifies the network signal and can support up to 64 child devices connected through it. Thanks to the EFR32MG21 chip and “Turbo Mode,” its range in open space reaches 200 meters — five times farther than the original ZBMINI. This makes it a critical building block for large Zigbee networks.
It also includes Detach Relay mode and supports multiple external switch types: momentary push buttons, SPDT, rocker switches, and dry contact sensors. Like the ZBMINIL2, it integrates seamlessly with Home Assistant via ZHA or Zigbee2MQTT.
What you need to know: requires neutral wire and a Zigbee hub. Maximum load: 10A.
Best for: users with large Zigbee networks who want to extend coverage while adding smart switch functionality.

Sonoff MINI DUO (MINI-ZB2GS) — Dual-Channel Zigbee in One Module (NEW 2025)
The MINI DUO is Sonoff’s major new release for anyone who needs to control two independent circuits from a single module. It runs on Zigbee 3.0, requires a neutral wire, and supports a total load of up to 16A (10A per channel).
Beyond controlling two lights or devices independently, it also acts as a Zigbee router with Turbo Mode, strengthening network coverage. It includes a “Stepper” function that allows a single physical button to cycle through multiple states or scenes in sequence.
It pairs instantly with Home Assistant via Zigbee2MQTT, where it appears as a dual switch with separate entities for each channel. Also compatible with Alexa, Google Home, and eWeLink.
What you need to know: requires neutral wire and a Zigbee hub. The mounting box must be at least 60 mm deep.
Best for: double switch setups — bathroom with light and fan, living room with multiple circuits — in a Zigbee installation.

Sonoff MINI DUO Matter WiFi (MINI-2GS) — Two Channels, No Hub Needed (NEW 2025)
The MINI-2GS is the WiFi and Matter version of the MINI DUO. It offers exactly the same dual-channel capability (up to 16A total), but connects directly to your WiFi router without requiring any hub.
Thanks to Matter, it integrates natively with Apple Home, Google Home, Amazon Alexa, and Home Assistant by scanning the pairing QR code. It includes Detach Relay mode and supports standard wall switches. Its dimensions (39 x 39 x 18 mm) allow installation in European 60-type boxes and most standard US boxes.
What you need to know: requires neutral wire and a 2.4 GHz WiFi network. Minimum mounting box depth: 60 mm.
Best for: dual-circuit rooms in homes without Zigbee that want cross-platform integration through Matter.

Sonoff DUALR3 — The Go-To for Blinds and Roller Shutters
The DUALR3 is Sonoff’s reference module for controlling motorized blinds, roller shutters, and electric awnings. It has two independently controlled channels with built-in power metering for each.
It includes three motor-specific operating modes: shutter mode (up/down), interlock mode (activating one channel automatically deactivates the other), and pulse mode (the relay turns off automatically after a set time). This makes it compatible with most tubular blind motors on the market.
It can also control two independent lights, although the MINI DUO is a more compact choice in that scenario.
What you need to know: requires neutral wire. Maximum load: 3300W per channel.
Best for: electric blinds, motorized awnings, or any installation requiring two relays with motor control logic.

Sonoff MINI-D — For Garage Doors, Boilers, and Irrigation
The MINI-D is a dry contact relay module with Matter support. Unlike the rest of the MINI family, it does not switch mains power for lighting directly — instead, it opens or closes a low-voltage control circuit (no load current).
This makes it ideal for devices that already have their own control system: garage doors, electric gates, boilers, irrigation systems, and solenoid valves. It accepts both AC and DC power (12–48V), which significantly broadens its range of applications.
What you need to know: not suitable for switching lights directly (it is not a mains power relay). Maximum output load: 8W.
Best for: automating garages, boilers, or irrigation without needing a hub.

Smart Wall Switches: When You Want to Change the Look
If you prefer to fully replace your existing switches with modern touch panels, these are the most relevant models.
Sonoff TX Gen2 — Touch Panel, Matter, Works With Everything
The TX Gen2 is the most up-to-date version of Sonoff’s touch wall switch lineup. Available in 1, 2, and 3-gang versions, it features a tempered glass panel and replaces a conventional wall switch in the same space.
It supports Matter, enabling direct integration with Apple Home, Google Home, and Alexa. Requires a neutral wire and a 2.4 GHz WiFi network.
Best for: anyone who wants a clean, modern touch finish throughout the home with universal ecosystem compatibility.

Sonoff NSPanel Pro — The Central Control Panel for Your Home
The NSPanel Pro is the most advanced product in the Sonoff lineup. It features a built-in color touchscreen that lets you control all devices in the home from one fixed point without picking up your phone. It also acts as a Zigbee hub and a conventional wall switch.
Its price is notably higher than the rest of the range ($65–$90), but it delivers a much more complete experience for users who want centralized smart home control.
Best for: the living room or main bedroom, as a central control hub for the entire smart home.

The Sonoff Ecosystem: What Else You Might Need
When Do You Need a Zigbee Hub?
If you choose any Zigbee model (ZBMINIL2, ZBMINIR2, MINI DUO ZB), you will need a hub to connect them to the internet and control them via app or voice assistant.
Sonoff’s own options are the ZBBridge Pro (more affordable, ideal for smaller networks) and the iHost (a local hub with its own processor that runs independently of the cloud). If you use Home Assistant, the most flexible alternative is the Sonoff Zigbee 3.0 USB Dongle (ZBDongle-E), which turns any computer or Raspberry Pi into a Zigbee coordinator.

Home Assistant Integration
All Sonoff Zigbee models integrate with Home Assistant via Zigbee2MQTT or ZHA with no special configuration required. WiFi models that support Matter integrate directly through the Home Assistant Matter add-on. This seamless compatibility is one of the main reasons Sonoff has become so popular in the Home Assistant community.
The eWeLink App
All Sonoff WiFi devices are managed through the eWeLink app, available for Android and iOS. It lets you create automations, set schedules, share control with family members, and configure scenes. The free tier covers the needs of most users; a paid tier (eWeLink Advanced, approximately $9.90/year) unlocks advanced automation with multiple conditions and IFTTT access.
Frequently Asked Questions
Does Sonoff work without internet? Matter-enabled WiFi models work locally as long as your home router is running, even without an active internet connection. Zigbee models also work locally when used with Home Assistant or the Sonoff iHost. The eWeLink app requires internet for remote control from outside your home.
Is Sonoff safe? Is it certified? Yes. Recent models carry CE certification (mandatory in the EU), FCC certification (required in the US), and RoHS compliance. Matter-certified models also hold official certification from the Connectivity Standards Alliance (CSA). Housings are made from flame-retardant polycarbonate.
Does Sonoff work with Apple HomeKit? Matter-enabled models (MINIR4M, MINI-2GS, MINI-D, TX Gen2) are natively compatible with Apple Home. Models without Matter are not directly compatible with HomeKit, but can be bridged through Home Assistant using the Homebridge add-on.
How many devices does the free eWeLink plan support? The free eWeLink plan has no device limit. The main restriction is that advanced automation — more than one condition or chained action — requires the paid plan (eWeLink Advanced, approximately $9.90/year).
Sonoff vs Shelly — which is better? Both are excellent brands. Shelly has an edge in local-only control without any cloud dependency and in load capacity on some models. Sonoff has an edge in price, catalog breadth, and Matter integration on recent models. For Home Assistant users, both brands work equally well.
Does Sonoff MINI require a neutral wire? It depends on the model. The MINIR4M, ZBMINIR2, MINI DUO ZB, and MINI DUO WiFi all require a neutral wire. The ZBMINIL2 and MINI DUO-L are specifically designed for no-neutral installations.
Conclusion
Sonoff’s 2026 lineup covers virtually every residential smart home need. As a starting point, the MINIR4M remains the most balanced choice for most homes: it requires no hub, works with all major ecosystems through Matter, and its price is hard to beat.
If you already have a Zigbee network or run Home Assistant, the ZBMINIR2 (with neutral) or ZBMINIL2 (without neutral) are the most solid options. And if you need to control two circuits from a single module, the new MINI DUO — available in both Zigbee and WiFi/Matter versions — is one of the most significant additions to the Sonoff lineup in 2025.
The key is to answer those three initial questions first: whether you have a neutral wire, which protocol fits your setup, and whether you prefer a hidden module or a visible switch. Once you have those answers, any choice in this guide is a safe bet.
