Description
SONOFF BASIC-ZB1GSP Zigbee DIN Rail 32A Smart Relay
The SONOFF BASIC-ZB1GSP is a compact Zigbee 3.0 DIN rail smart relay designed for high-current circuits up to 32A. It combines remote switching, real-time energy monitoring and configurable electrical protection in a slim single-module design, making it ideal for switchboard-based smart home and energy management applications.
Supporting 100–240V AC and loads up to 7680W, the BASIC-ZB1GSP is suitable for controlling and monitoring hot water systems, heating, pumps, appliances and other dedicated electrical circuits.
Energy Monitoring
Built-in energy monitoring provides real-time measurement of voltage, current, power and accumulated energy consumption, allowing users to track circuit performance and identify high-energy loads.
Historical energy data can also be viewed through compatible platforms, making the relay well suited to energy management and load optimisation applications.
Configurable Protection
The BASIC-ZB1GSP supports configurable protection thresholds for current, voltage and power. If a set limit is exceeded, the relay can automatically disconnect the connected load.
These functions provide additional monitoring and protection but do not replace the circuit protection required by electrical regulations.
Double-Pole Switching
The relay provides double-pole switching, disconnecting both active and neutral when switched off.
Its compact 84 × 66.5 × 18mm DIN rail design allows straightforward installation within compatible switchboards and distribution enclosures.
Zigbee 3.0 Connectivity
Using Zigbee 3.0, the BASIC-ZB1GSP can be integrated with compatible SONOFF Zigbee gateways, eWeLink and supported third-party automation platforms such as Home Assistant.
As a permanently powered Zigbee device, it also operates as a Zigbee router, helping strengthen and extend the Zigbee mesh network.
Key Features
- Supports remote switching, schedules and smart scene automation through a compatible Zigbee 3.0 hub or software (such as Home Assistant).
- Standard DIN Rail Installation: Mounts neatly inside compatible electrical distribution boards without drilling or modification.
- 32A High-Load Capacity: Controls loads up to 7680W, making it suitable for EV chargers, water heaters, floor heating, heat pumps and other high-power appliances.
- Real-Time Energy Monitoring: Tracks voltage, current, power and energy consumption, with historical data storage and export support.
- Local energy data continues to be recorded while the Zigbee connection is offline and synchronises after reconnection.
- Adjustable Overload Protection: Set custom current, voltage and power limits to automatically switch off the output when a threshold is exceeded.
- Double-Pole Switching: Disconnects both active and neutral conductors for improved circuit isolation and safety.
- Power-on setting lets you choose the switch state when power is restored.
