Sonoff T2EU1C-RF 433MHz Wireless Stick-on 1 Gang Smart Wall Switch 433MHz RF Frequency White

New Sonoff RF (433.92 MHz radio control) touch switches have similar features as SmartWise T1R1 series RF switch but come with a similar modern look to Sonoff TX T2 smart switches. It is typically used as a wireless 2-way switch for Sonoff TX switches, or a wireless switch for Sonoff and SmartWise RF relays, and needs no wiring but works with 2 pcs 3V batteries. Inside the wall switch case, there is a 433MHz RF (radio) remote control. The device is not for standalone use, pair it wirelessly with Sonoff TX T1, T2, T3 series (1C, 2C, 3C) switches via radio frequency, Sonoff RF or Sonoff 4CH Pro smart relay, or an RF gateway such as Sonoff RF Bridge or SmartWise RF Bridge. Fix it to the wall with screws or double-sided adhesive. No need for wiring at all, it controls other T1/TX switches via radio frequency. No inside-the-wall part, no need for an in-wall electric socket. The remote controller works to add the ability to control the lights from a distance and does not require wiring, simply use a stick or screw, and ready to use. The multiple gang version allows you to pair with different RF receivers, so one SONOFF remote controller supports controlling multiple lights. The remote controller can be used to connect with SONOFF T1/T2/T3 wall switch to achieve two-way control. It is also used for RFR2, RFR3, 4CHPROR3, and SlampherR2 which provides you one more control way except for APP remote control and voice control. The backlight is designed on the touch button to give you a clear location to control the light at night. The absorbing energy from light decides the brightness of the backlight, the more energy it absorbs, the higher its brightness. Three using methods can be chosen stick-on, screw-on, and desktop.
