SONOFF BASIC DIN Rail Matter Smart Switch (BASIC-1GSP)
Professional Smart Control for High-Power Electrical Circuits
Bring intelligent automation, energy monitoring, and advanced protection to your electrical distribution board with the Sonoff Basic DIN Rail Matter Smart Switch (BASIC-1GSP). Designed for installation on a standard 35mm DIN rail, this powerful 32A Matter over WiFi smart relay gives homeowners, installers, and businesses a reliable way to control and monitor high-power electrical circuits from anywhere.
Whether you’re automating a geyser, EV charger, underfloor heating, heat pump, pool pump, or other high-load appliances, the BASIC-1GSP combines industrial-grade performance with the simplicity of modern smart home technology.
Built for Distribution Boards
Unlike standard inline smart switches, the BASIC-1GSP is purpose-built for installation inside electrical distribution panels.
Its compact DIN rail design allows for clean, professional installations without additional brackets or modifications, making it ideal for:
- Residential distribution boards
- Commercial electrical panels
- Industrial control cabinets
- Smart building installations
- Energy management systems
Simply clip it onto any standard 35mm DIN rail for a tidy, secure installation.
Powerful 32A Switching Capacity
Control demanding electrical loads with confidence.
The BASIC-1GSP supports loads of up to 32A (7680W), making it ideal for controlling:
- Electric vehicle (EV) chargers
- Geysers and water heaters
- Underfloor heating systems
- Heat pumps
- Pool pumps
- Air conditioning circuits
- High-power appliances
- Dedicated power circuits
Its heavy-duty design makes it suitable for applications beyond the capabilities of conventional 10A smart switches.
Monitor Your Energy Usage in Real Time
Gain valuable insight into your electricity consumption.
The integrated energy monitoring system provides live measurements of:
- Voltage
- Current
- Power (Watts)
- Total energy consumption (kWh)
View historical daily and monthly energy usage through the eWeLink app, estimate operating costs, identify energy-hungry appliances, and make informed decisions to reduce electricity bills.
Perfect for homeowners looking to improve energy efficiency or businesses wanting better visibility of power usage.
Advanced Electrical Protection
Protect your equipment with intelligent safety features.
The BASIC-1GSP includes configurable protection for:
- Overload
- Over-voltage
- Over-current
- Over-power
If any threshold is exceeded, the device can automatically disconnect the circuit to help protect connected equipment.
For added safety, double-pole switching disconnects both the Live and Neutral conductors, providing complete electrical isolation when switched off—an important advantage for high-power installations.
Matter Certified for a Future-Proof Smart Home
Enjoy seamless compatibility across the world’s leading smart home platforms.
The BASIC-1GSP works with:
- Apple Home & Siri
