SONOFF “Basic DIN Rail”, codenamed BASIC-1GSP, is a Matter Over WiFi smart switch designed to be installed in electrical distribution boxes with a DIN rail, and it also supports real-time energy monitoring to track voltage, current, power, and energy consumption.
The BASIC-1GSP can handle high-power circuits up to 32A (7,680W @ 240V AC), which makes it suitable for electric floor heating, EV charging stations, water heaters, and other heavy-duty devices. The device also focuses on safety with customizable overload protection & a double-pole safety switch.

The SONOFF BASIC-1GSP is supported by the eWeLink mobile app, and since it works over Matter, you can scan the Matter QR code on the Quick Guide or the device itself to add the device to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Home Assistant, or other Matter-compatible apps.
However, note that some features like OTA firmware upgrades are only supported in the eWelink app, and power/energy monitoring is currently limited to eWelink, Home Assistant, and Samsung SmartThings platforms. The SONOFF Basic DIN Rail smart switch can also be used in LAN mode without access to the Internet, and supports features such as voice control, schedules, inching, and basic remote control (on/off). The user manual provides instructions to get started.
The device is not the first DIN rail-compatible switch from SONOFF, as the earlier 4CH Pro R3 switch offered a larger 4-gang switch, and the company also sells the SONOFF DR DIN Rail Tray as an accessory bracket for mounting various SONOFF modules. The BASIC-1GSP is still unique as a compact DIN Rail smart switch with Matter over WiFi connectivity.
SONOFF sells the BASIC-1GSP for $19.90 on its online store. The coupon code CNXSOFT can lower that price by 10 percent to $17.91.

So, old router wi fi 4 must special keept for sonoff devices because wifi 6 or 7 are out from range?
Wi-Fi is backward-compatible. WiFi 4 devices will work just fine with Wi-Fi 6/7 routers.
