SONOFF Basic DIN Rail Matter-enabled WiFi smart switch 32A (BASIC-1GSP)
SONOFF Basic DIN Rail (BASIC-1GSP) is a modern WiFi smart switch with full support for the Matter standard, designed for convenient and lightning-fast mounting on standard DIN rails in distribution boards. The device handles currents up to 32A, making it an excellent choice for controlling high-power equipment such as car charging stations, electric heating, or heat pumps, while offering precise real-time energy consumption monitoring .
Key features:
- Standard DIN rail mounting: quick and hassle-free installation in residential and industrial electrical distribution boards.
- Energy monitoring: real-time tracking of voltage, current, and power with the option to export historical data.
- Load support up to 32A (7680W): dedicated to the most demanding heating and power systems.
- Double safety switch: physical, double-pole cutoff of the phase and neutral wire ensuring complete isolation.
- Matter compatibility: seamless integration with Apple Home, Google Home, Amazon Alexa, and Samsung SmartThings (Matter hub required).
Full electrical isolation for maximum safety
Advanced double-pole switching in the SONOFF device automatically cuts off the circuit by disconnecting both the phase and neutral wires simultaneously. This guarantees 100% physical electrical isolation, which directly translates to safety during use and any maintenance work within your installation.

Monitor energy consumption and save on bills
The Basic DIN Rail smart relay enables accurate monitoring and analysis of power demand. Clear interfaces with intuitive charts in dedicated apps allow you to track daily, monthly, and semi-annual consumption. Thanks to cost calculators, you can easily identify the most power-hungry devices and effectively reduce your expenses.

Seamless operation in the Matter ecosystem
The relay gains flexibility thanks to full support for the Matter protocol. This means that once a compatible hub is connected, you can smoothly integrate the module with many leading Smart Home solutions, deciding for yourself whether you prefer to use the Apple, Google, or Alexa environment.
