The SONOFF Basic DIN Rail Matter over Wi-Fi Smart Switch (BASIC-1GSP) is a 32A smart switch that mounts on a standard DIN rail inside your electrical distribution box. It brings remote control, real-time energy monitoring and overload protection to high-power circuits such as electric floor heating, EV charging stations and water heaters.
It tracks voltage, current, power and energy use in real time, calculates electricity cost and stores history you can export. Set your own voltage, current and power limits and it cuts the output automatically, while its double-pole design disconnects both live and neutral. Matter certification lets it work with Apple Home, Google Home, Amazon Alexa and Samsung SmartThings.
