- Double-pole switching: simultaneously opens the live and neutral for full electrical isolation of the line.
- Loads up to 32A: mounts in the distribution board and controls an entire line, not a single outlet.
- Built-in energy monitoring: read the entire line’s data in the eWeLink app.
- Does not work standalone: requires a compatible Zigbee hub, sold separately; without a hub it cannot connect to the app.
- Configurable overload protection: set current, voltage, and power limits after which it will switch off automatically.
- Does not replace the circuit breaker: adds to the installation’s protection; it does not replace it.
- UniBusbar relay: less heat, higher current, and longer lifespan compared to a traditional relay.
- Solid copper terminals: integrated into the body for reliable contact at high currents.
- V-0 enclosure: the highest rating on the UL 94 scale for fire resistance.
- Zigbee 3.0: integrates with open-source platforms, including Home Assistant and MQTT.
- Apple Home via Matter Bridge: requires a compatible hub acting as a bridge.
- DIN-rail mounting: install in the distribution board with the power isolated.

Sonoff BASIC-ZB1GSP: 32A Zigbee DIN Rail Smart Switch with Power Measurement
The SONOFF BASIC-ZB1GSP is a smart DIN rail switch : it mounts in the electrical panel , not behind a socket, and is the right place to control an entire line instead of a single light point. Its distinguishing feature is double-pole switching : it opens the phase and neutral together, and this provides complete electrical isolation on the line, both during operation and when you get your hands on it for maintenance. It can handle loads up to 32A , measures consumption and allows you to set current, voltage and power limits beyond which it turns off automatically. It works on Zigbee 3.0 and requires a compatible Zigbee hub : it does not connect to the app on its own.
Double Pole, Solid Copper, Consumption Measurement and 32A: the Functions at a Glance
The BASIC-ZB1GSP 's features at a glance: double-pole switching between phase and neutral, integrated solid copper terminals , energy measurement , loads up to 32A , and Zigbee 3.0 . These five features are explained one by one in the sections below.

Complete Electrical Insulation: Double Pole Switching Opens Phase and Neutral
Double-pole switching disconnects both the live and neutral lines. This is the difference that matters in a switchboard: a single-pole switch leaves the neutral connected, and the line remains partially live even when off. Opening both poles provides complete physical electrical isolation , making both operation and maintenance safer—when someone needs to work on that line, it's truly disconnected.
Envelope with Fire Resistance Grade V-0, the Highest on the Scale
The casing has a V-0 fire resistance rating, the highest on the UL 94 scale: the material self-extinguishes in a few seconds and does not drip flammable material . In an electrical panel, this is more important than anywhere else, because it is a closed environment, full of live conductors and plastic, where a fire can't stop anything. It's the kind of detail you never see and notice only once.
UniBusbar Relay: Less Heat, Higher Current, and Longer Life
SONOFF's UniBusbar relay is the part that carries the current into the device. Compared to a traditional relay, it generates less heat , supports higher current , and has a longer lifespan . These three things are connected: heat is the contacts' primary enemy, and reducing it means the component can withstand more and last longer. This is why this model reaches 32A .
Monitor Energy Consumption Directly in the eWeLink App
The device measures the consumption of the line it controls and displays it in the eWeLink app . Mounted in the dashboard, this means you can read the consumption of an entire circuit —the kitchen, the garage, the pump, the charging station—rather than a single appliance plugged into an outlet. This is the data you need to understand the true cost of your bill before deciding what to do about it.
Overload Protection with Current, Voltage and Power Limits
The app lets you set current (up to 32A ), voltage , and power limits: when the line exceeds the threshold, the device turns off automatically . It's a configurable overload protection that adds to the system's protection without replacing it: the circuit breaker stays in place and does its job.
It integrates with Home Assistant, MQTT and Open Source Zigbee 3.0 platforms
Based on the Zigbee 3.0 standard, it integrates with third-party open-source platforms , including Home Assistant and MQTT . This is the advantage of sticking to a standard rather than a closed system: the device continues to function even when the home's control software changes.
Works with Apple Home via Matter Bridge and a compatible hub
The device enters Apple Home through a Matter Bridge , which brings SONOFF Zigbee products into Apple Home and makes them usable in scenes and automations . A compatible Matter hub therefore needs to act as a bridge: the switch alone does not appear in Apple Home.
Compatibility with Sonoff Zigbee Hubs
To connect the BASIC-ZB1GSP to the network, you need a compatible SONOFF Zigbee hub : this is the most direct connection and the one the device is designed for. The hub coordinates the Zigbee network, maintains the connection to the app, and allows the switch to communicate with other devices. Without a hub, the product won't work , and should be considered before ordering.

Frequently Asked Questions
Does the BASIC-ZB1GSP work without a hub?
No. It's a Zigbee device: you need a compatible Zigbee hub , sold separately. It doesn't connect to the app on its own.
What load can it handle?
Up to 32A . This is why it is mounted in the panel : it controls an entire line, not a single socket.
What does double pole switching mean?
It opens the phase and neutral together. A single-pole switch leaves the neutral connected and the line remains partially live even when off; with a double-pole switch, the isolation is complete .
Does it measure consumption?
Yes. Energy measurement is integrated and the data can be read in the eWeLink app , referring to the entire line that the switch controls.
Can it be turned off automatically in case of overload?
Yes. You can set current , voltage , and power limits using the app: if the threshold is exceeded, the device turns off. It doesn't replace the circuit breaker , it's just an addition.
Where is it installed?
On a DIN rail , inside the electrical panel . Installation is on a mains voltage system and must be done with the panel disconnected, by an electrician if you are not familiar with it.
Does it work with Home Assistant?
Yes. It is Zigbee 3.0 and integrates with third-party open-source platforms, including Home Assistant and MQTT .
Does it work with Apple Home?
Yes, via Matter Bridge : you need a compatible hub to act as a bridge. The switch alone won't appear in Apple Home.
