Wall-mounted smart light switch Sonoff T2 EU TX 3-channel Wi‑Fi + RF 433 control

Sonoff T2 EU TX 3-channel Wi‑Fi + RF 433 wall-mounted smart light switch is a recessed in-wall control device that enables independent switching of three separate circuits. It supports connection to a home Wi‑Fi network for remote control via a mobile app and also accepts commands from RF 433 remote controllers for local operation. The switch is designed to replace a standard EU wall switch and provides basic scheduling and automation features when paired with Sonoff ecosystem apps and compatible smart home platforms.

Advantages

The switch offers three individually controlled channels in a single wall plate, allowing separate control of multiple lights or loads without additional wiring changes. Dual control modes — Wi‑Fi for app-based remote access and RF 433 for direct local control — add flexibility for different use scenarios. The touch-capacitive front and LED indicators enable intuitive local operation and status feedback, while in-wall form factor preserves the appearance of conventional switches.

Suitable for

• Controlling multiple lighting circuits in living rooms, bedrooms, or corridors
• Operating ceiling fans or range hoods with separate speed or on/off lines
• Integrating basic schedules and scenes within a smart home setup
• Replacing traditional triple wall switches with a single smart panel

How to use

Install the switch into a standard EU in-wall box following the wiring diagram and safety instructions in the manufacturer documentation, ensuring power is disconnected during installation. After physical installation, connect the device to a 2.4 GHz Wi‑Fi network via the Sonoff app to enable remote control and automation features. Pair an RF 433 remote if local wireless control is needed. Use the app to assign each channel, set schedules, and configure basic scenes; local touch control and LED indicators provide immediate manual operation and status information.

Recommendations

Verify compatibility of connected loads with the switch's rated AC specifications and comply with local electrical codes. For reliable Wi‑Fi operation, ensure the device is within adequate range of the router and avoid 5 GHz-only networks. Use qualified personnel for installation if you are not experienced with in-wall electrical wiring.
