SONOFF Basic DIN Rail 32A Zigbee Smart Switch BASIC-ZB1GSP

SONOFF Basic DIN Rail 32A Zigbee Smart Switch (BASIC-ZB1GSP)

Take full smart control of your high-power circuits with the SONOFF Basic DIN Rail Zigbee Smart Switch (BASIC-ZB1GSP). This professional-grade single-channel 32A DIN-rail smart relay mounts cleanly inside your distribution board and is ideal for South African homes and businesses that need reliable control and monitoring of heavy loads such as geysers, heat pumps, underfloor heating, pool pumps, EV chargers and major appliances.

Key Features

• 32A High-Power Capacity – Handles up to 32A / 7680W (at 240V). Perfect for demanding circuits that standard smart plugs and mini modules cannot handle.
• Real-Time Energy Monitoring – Tracks voltage, current, power and total energy consumption. View daily, weekly, monthly and up to 180-day historical data with export support so you can identify energy hogs and reduce electricity bills.
• Double-Pole Switching – Simultaneously disconnects both Live and Neutral for complete physical isolation, improving safety during maintenance and reducing residual risk.
• Adjustable Overload Protection – Set custom voltage, current and power thresholds. The device automatically cuts power when limits are exceeded.
• Zigbee 3.0 + Router Function – Stable, low-power mesh connectivity with strong interference resistance. Acts as a mains-powered Zigbee router to extend and strengthen your Zigbee network.
• Standard DIN Rail Mount – Clips directly onto a standard 35mm DIN rail inside the DB board for a clean, permanent installation (no drilling required).
• Home Assistant & Local Control Ready – Works excellently with Home Assistant (ZHA or Zigbee2MQTT), Zigbee2MQTT, SmartThings, Homey and other Zigbee 3.0 hubs. Fully local control is possible — no cloud dependency required when used with a compatible coordinator.
• Extra Convenience Features – Schedules, timers, inching mode, power-on behaviour settings, and smart scene automation.

Ideal Applications

• Geyser control and energy monitoring
• Heat pumps and underfloor heating
• EV charger circuits
• Pool pumps and high-power appliances
• Workshop or commercial high-load circuits
• Any circuit where you want centralised smart switching + accurate power metering inside the DB board

Technical Specifications

Important: This is a DIN-rail device designed for installation inside an electrical distribution board. It must be installed by a qualified electrician. A Zigbee 3.0 coordinator/hub is required (e.g. SONOFF ZBDongle-E/P, ZBBridge, Home Assistant Green + Zigbee stick, etc.).

Upgrade your distribution board with professional-grade smart control and energy visibility. The SONOFF BASIC-ZB1GSP is one of the best high-current Zigbee solutions currently available for serious Home Assistant and smart home installations.
