Sonoff T2EU1C-RF gateway/controller White Plastic Wall mounting 0.433 GHz

SONOFF 433MHz Wireless Stick-on Smart Wall Switch is a compact, stick-on RF controller designed to resemble the SONOFF TX series touch switches. The white plastic wall-mounted unit operates at 433 MHz and can be attached to any flat surface to control compatible SONOFF devices or paired TX wall switches without additional wiring.

Advantages

The device offers flexible placement thanks to its adhesive backing and a slim 86 × 9 × 86 mm profile, enabling control from convenient locations. Multiple RF stick-on switches can be linked to a single SONOFF smart switch to provide several control points. A multi-channel design lets one stick-on controller manage multiple lights or scenes from one position. It supports two-way control by pairing with SONOFF TX wall switches, allowing operation of the same light from two locations. The 433 MHz RF protocol provides simple remote control compatibility with select SONOFF products.

Suitable for

• Adding a remote touch control next to beds, sofas or desks
• Expanding control points without rewiring stairs or long corridors
• Controlling multiple lights or zones from a single wall position
• Using as a wireless remote for compatible SONOFF 433 MHz devices
