Introduction
The Sonoff Touch is a touch controlled panel wall switch. It is based on the ESP8285 chip and can control one relay. Behind the blue tape there's a LED which you can control as you like. Other than normal on or off when the ceiling light (or what ever you control with the relay) you might want to flash it on-off-on-off when the morning news paper is delivered to your mailbox.
Hardware
- ESP chip version: ESP8285
- Flash size: 1M
- Onboard USB-TTL converter: No
- GPIO's broken out/available to free use: None
- GPIO tied to onboard hardware: 0 (button), 12 (Relay 2A@230VAC), 13 (LED blue)
- Power supply information: 90-250VAC
- Antenna: onboard PCB antenna
Wiring/flashing
A programmer is needed to flash this device.
Programmer ESP TX <--> RX (2nd via) RX <--> TX (3rd via) Power 3.3V <--> VCC (1st via [square]) GND <--> GND (4th via) + GPIO-0
In order to get the ESP8285 in flash mode the GPIO-0 needs to be LOW. (See picture with explanations below)
Remember to remove GND from GPIO-0 once flashed.
Already soldered board fitted in the casing.
Soldered board seen from front.
Soldered board seen from bottom, square via as far left out of the four.

Devices
Switch
Push button active high will make the relay pull when button is released, push button active low will pull the relay (instantaneously) when button is touched. What you prefer.
Relay
Switch to Relay rule
on touch#switch do if [touch#switch]=1 gpio,12,1 else gpio,12,0 endif endon
LED rule
Depending if you want the LED to be on or off when the relay is open/closed you may use this rule:
on relay#switch do if [relay#switch]=1 //change this [relay#switch]=0 for LED off when relay is closed gpio,13,1 else gpio,13,0 endif endon
To control the brightness you may use the PWM command instead of GPIO command.
