Wiring/flashing

A programmer is needed to flash this device.

(Progammer -> ESP8285):

3.3V -> VCC (first via [square] on board) 
TX -> RX (second via on board)
RX -> TX (third via on board)
GND -> GND (forth via on board)

In order to get the ESP8285 in flash mode the GPIO-0 needs to be LOW. (See picture with explanations below.)

LED

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 do  //change this [relay#switch]=0 for LED off when relay is closed
   gpio,13,1
  else
   gpio,13,0
  endif
