- Switches on/off and measures: a single module behind the wall switch controls the appliance and tells you how much it consumes, hour by hour.
- Bill in euros, not kWh: set your tariff and time-of-use bands, and the app shows how much you’re spending.
- Reads solar PV too: measurement is bidirectional, so you see the energy your panels produce and what you export to the grid.
- Alerts you and disconnects automatically: if current, voltage, or power go out of range, you receive a notification and the relay cuts power to the load.
- Cycle-end and maintenance alerts: know when the washing machine has finished and when it’s time to change the filter.
- Timers, voice, and scenes: fixed schedules, commands via Alexa and Google Home, lights that turn on with the motion sensor.
- Keep your existing switch: the S1 terminal accepts a wall switch or push button, and with the relay disengaged smart bulbs stay permanently powered.
- Handles 16 A: that’s 3840 W at household voltage, enough for a water heater, oven, or induction cooktop.
- Works even without a hub: with proximity Bluetooth you can control it from your phone at close range.
- Strengthens your home network: acts as a Zigbee repeater and extends coverage up to 250 meters in Turbo mode.
- Small and discreet: 39.5 × 33 × 16.8 mm and 27.3 g, fits in a 60 mm flush-mount box.
- Open to self‑hosted systems: Home Assistant, Zigbee2MQTT, Apple Home via Matter Bridge, and Zigbee binding.
- Connects to the Sonoff Zigbee hub: the gateway adds it to the eWeLink app and is sold separately; a neutral wire is required in the box.
- Electrician installation: power off, with an upstream 16 A circuit breaker. If you only need metering, the model without a relay is the MINI-ZB1GP.

Sonoff MINI-ZB1GSP: Turn On, Off, and See How Much Energy Each Appliance in Your Home Consumes
The Sonoff MINI-ZB1GSP is a small smart switch that hides behind an outlet or switch and does two things at once: it turns the connected appliance on and off , and tells you how much it consumes . You can control it from your phone, with your voice, or with the wall switch you already have, and see the watts per hour. It speaks Zigbee 3.0 , the network that home devices use together without clogging up your Wi-Fi: it needs a Sonoff Zigbee hub to connect it to the eWeLink app. It can handle up to 16 A , so you can place your washing machine, boiler, or heat pump underneath. With timers, it turns on at seven and off at ten; with scenes, it turns off the lights when you leave. If you have panels, it also reads the energy you produce. And it's the brother of the MINI-ZB1GP: the former only measures, the latter measures and controls.
It Turns Off By Itself If Something Goes Wrong: The Protection That Monitors Your Home's Electrical System
The MINI-ZB1GSP doesn't just measure: it monitors. If the load draws more than it should, or the voltage deviates from normal values, it automatically cuts off the power and alerts you on your phone. This is the protection a traditional switch lacks, and it relies on appliances that remain on for long periods of time: the water heater, the space heater, the pool pump. It can handle up to 16 A and 3840 W , with a polycarbonate body and screw terminals. Installation is a job for an electrician .
Make What You Already Have Smart: Works with Your Home's Wall Switch
You don't have to change switches or redo the wiring. The MINI-ZB1GSP fits into the box behind the switch or socket you already use, and from there it controls and measures. Terminal S1 accepts your wall switch , whether the standard two-position one or the push-button reset: you can continue to use it as usual, and you also have the app. You can connect your boiler , oven , heat pump, and garden light. You need a flush-mounted box at least 60 mm deep, and the neutral wire inside the box.
It also acts as a Zigbee repeater: it extends the home network up to 250 meters in Turbo mode.
The MINI-ZB1GSP is powered by the mains, which allows it to do something battery-powered sensors can't: repeat the Zigbee signal . Each module you install becomes an additional bridge for other devices, and the home network strengthens itself. The useful range to the gateway is up to 180 meters ; with Turbo mode active, it extends up to 250 meters . In a multi-story house, this means the sensor in the basement will stop disappearing from the app.
How Much You Consume Every Hour, Every Day and Every Month, in Euros and Not Just in Kilowatt Hours
On your phone, you'll find hourly , daily , and monthly consumption graphs, and you can instantly see who's eating up your bill. Set your rate and time slots , and the eWeLink app shows you your spending in euros instead of just kilowatt-hours. Discover that your old refrigerator costs more than your new oven, or that your water heater runs at night when it's not needed. And since the MINI-ZB1GSP also has a relay, this discovery quickly becomes action: turn off the wasteful item from the app, or set a timer for it.
Read about Photovoltaics: See How Much Energy the Panels Produce and How Much You Use
The measurement is bidirectional : it counts the current coming in and going out. If you have panels on your balcony or a small system, you can place it on the panel line. And you can see in real time how much energy they're producing and how much you're sending back to the grid . In the app, you set production as a negative value, and the graphs distinguish between what you consume and what you generate. It's concrete proof of how much your panels are saving you, month after month, without waiting for the bill.
It alerts you on your phone when your washing machine or dishwasher has finished its cycle.
Set a power threshold and a time, and the MINI-ZB1GSP notifies you when the load drops below that value. In practice: the washing machine finishes, the power drops, and your phone alerts you. The adjustable delay prevents the loading and unloading pauses, which last just a few seconds, from being mistaken for the end of the cycle. So you hang out the laundry when it's ready, not an hour later, and the notification reaches you wherever you are. It works with any appliance that has a cycle: dishwasher , dryer , bread maker.
Counts your working hours and reminds you when to change the filter or do the service.
Every appliance has maintenance you forget: the purifier filter, the dehumidifier tank, the heat pump service. The MINI-ZB1GSP counts the operating hours over a power level you choose, and when you reach the set interval, it sends you a reminder . There's no need to mark anything on the calendar: the module knows how long the appliance has actually worked. The counter resets after the intervention, and the cycle starts again. It's a small detail that extends the life of everything you have at home.
If Current, Voltage or Power Go Out of Limits, You Get the Alarm and It Shuts Off By Itself
You set the values you consider normal for current , voltage , and power , and if any of these exceed the limits, an abnormal consumption warning goes off. A motor that draws more than usual, a boiler that stays on all night, a voltage that drops too low: you can see it on your phone before it becomes a fault. And here's where the MINI-ZB1GSP makes a difference compared to the model that only measures: it has a relay , so it can automatically cut off power to the load as soon as the alarm goes off. No additional device is needed.
Smart Bulbs Stay Smart: With the Relay Off, the Wall Switch No Longer Turns Them Off
Anyone who owns smart light bulbs knows the problem: someone turns off the wall switch, the bulb loses power, and disappears from the app. With the MINI-ZB1GSP 's relay-off mode, the problem is solved. The module keeps the bulb powered at all times and uses the wall switch as a control : press it, and it sends the command to the bulb to turn on or off via the app, without cutting off the power. It works with regular switches and push-button switches. The bulb remains accessible via voice, scenes, and your phone, always.
Timer, Voice Commands and Scenes: Responds to Alexa and Scenes
With timers , you can set the schedule: the driveway light comes on at seven, off at ten, every day or only on weekends. You can control the device with your voice from Alexa or Google Home by connecting the eWeLink app to the assistant; a smart speaker is required. With scenes, you can connect the MINI-ZB1GSP to other devices: the SNZB-03P motion sensor detects someone in the hallway and the light turns on automatically, then turns off when no one is there. Three different ways to never touch a switch again.
What You Need to Make It Work: The Zigbee Hub, and What It Does Without a Hub Thanks to Bluetooth
To have it in the eWeLink app with all its functions, you need a Sonoff Zigbee hub , which can be purchased separately from the Zigbee hubs in the catalog . But the MINI-ZB1GSP also has Bluetooth : with proximity mode, the phone connects directly to the module, without a hub, and you can turn it on, off, and adjust the basic settings. It's useful when the hub isn't yet available, or when the Zigbee signal in that room is weak. It doesn't replace the hub for consumption, timers, and scenes: it's a spare tire, and a spare tire that works.
Works with Apple Home through a Matter Bridge: Bridge Ultra, iHost, or a USB Stick
If you control everything at home from Apple Home , the MINI-ZB1GSP enters through a Matter Bridge : a Sonoff hub that speaks Zigbee on one side and Matter on the other. There are two ways. The first is a certified hub like Zigbee Bridge Ultra or iHost . The second is a Sonoff Zigbee dongle connected to a small server with eWeLink CUBE , Sonoff's free software. In both cases, the switch appears in the Home app and in Apple automations, on iPhone, iPad, Mac, and Apple Watch. And you can also control it with Siri .
It also works with Home Assistant and Zigbee2MQTT, with a Dongle Series Key
If you don't want to go through the cloud, the MINI-ZB1GSP speaks the Zigbee 3.0 standard and can be integrated with the systems you manage in your home. With a Sonoff Dongle connected to your server, Home Assistant and Zigbee2MQTT see it as a switch with measurements: status, power, voltage, current, and energy. You can also choose what to do when the power returns and whether to activate Turbo mode for the range. On Home Assistant with ZHA , an extra step is required, which you only need to do once, to see all the measurements.
Zigbee Binding: The Button Talks Directly to the Module, Even If the Hub Is Off
Zigbee binding is a direct connection between two devices: after an initial configuration in Home Assistant , the SNZB-01M button sends the command directly to the MINI-ZB1GSP , bypassing the server. This means the light turns on even if the server is off or the network is down. And the response is immediate , without the half-second delay from the cloud. It works both ways: the module can be the recipient of a button, or the source that controls another device. It's the most reliable way to connect a switch to a light.
All the Functions of the MINI-ZB1GSP at a Glance
Here's a summary of what the MINI-ZB1GSP can do, without having to reread the whole thing. It turns the load on and off from the app, by voice, or from the wall switch. It measures voltage , current , and power in real time and keeps a history of consumption. It sends notifications for end-of-cycle, maintenance, and abnormal consumption, and automatically turns off in the event of an alarm. It has timers, scenes, a relay disconnected for smart bulbs, Bluetooth proximity, and Zigbee binding . It acts as a repeater for the home network. And it integrates with eWeLink , Apple Home, and open platforms.
MINI-ZB1GSP, MINI-ZB1GP, or ZBMINIR2: Which MINI Series Module Is Right for You?
The three modules are similar but serve different purposes. The MINI-ZB1GSP turns on, off, and measures up to 16 A : it's the most complete. The MINI-ZB1GP only measures and doesn't switch: it's cheaper, for those who just want to understand where the current is going. The ZBMINIR2 turns on and off up to 10 A but doesn't measure: it's more than enough for a light. All three use the same chip and act as a Zigbee repeater; only the GSP also has Bluetooth for proximity mode. The other MINI Zigbee modules in the catalog solve different problems.
How to Connect to Wires: N, L, Two L Outs and S1, and Then Four Steps in the App
The connection is an electrician 's job, with the power off. The N terminal goes to neutral and L to the incoming line. The two L Outs go to the load to be controlled, S1 to the wall switch if you want to keep it. It requires neutral on the wires: without it, the module will not be powered. It accepts copper conductors from 0.75 to 2.5 mm² . Upstream, you need a 16 A circuit breaker , and the line must be single-phase. Then, the four steps: turn on the power, open the app, add the device while it flashes for three minutes, give it a name. If you need to start over, press the button for ten seconds.
Frequently Asked Questions
Does it turn on and off, or does it just measure?
Both. The MINI-ZB1GSP has a relay and a meter. The MINI-ZB1GP model only measures.
Do you need a Zigbee hub?
Yes, you can have it in the eWeLink app with power consumption, timers, and scenes. Without a hub, you can turn it on and off from your phone using Bluetooth proximity and adjust the basic settings.
Can I keep my wall switch?
Yes. You connect it to terminal S1: it works with both the normal switch and the return button.
Do you need the neutral wire?
Yes. The MINI-ZB1GSP is powered by the line and will not work without a neutral.
How much load can it hold?
Up to 16 A, or 3840 W at your home's voltage. Enough for your washing machine, oven, boiler, or induction hob.
Are you measuring the solar panels on your balcony?
Yes. The measurement is bidirectional: in the app you set the production as a negative value and see how much energy you generate.
Does it work with smart bulbs?
Yes. With the relay off mode the bulb always remains powered and the wall switch becomes an app control.
What box do you need to install it?
A flush-mount box at least 60 mm deep. The module measures 39.5 × 33 × 16.8 mm.
Can I install it myself?
No. The installation must be done by an electrician, with the power off, with a 16 A circuit breaker upstream.
