Sonoff TX Ultimate Wall Switch 1/2/3/4-gang

Sonoff TX Ultimate Wall Switch 1/2/3/4-gang

Device Type: switch
Electrical Standard: euus
Board: esp32
Difficulty: Disassembly required, 3/5

Notes

  • Touch panel is operated by IC CA51F353S3, connected via UART.
  • Touch panel is the same for all models and has 10 channels (vertical regions), regardless of how many relays actually present. It supports also swipe-right and swipe-left.
  • It has 28 addressable WS2811 LEDs
  • It has a vibration motor, that can be combined with touch event
  • It has audio speaker over I2S
