The **four serial pins** (VC Programming the Sonoff Dual R2 is a breeze although the on-board-button is not connected to GPIO0. As with all ESP8266/ESP8285 modules pulling GPIO0 to GND is needed to put the chip in programming mode. You need to **connect GPIO0 and GND** during power up. +Sonoff Dual R2 + Luckily both Gnd and GPIO0 (as Button 0) are available on the second header. A simple jumper between GND and the Button 0 pin will do while programming will do. ### Configure Dual R2 -Sonoff Dual R2 - To control relays by external switches connected the switch to the header at the designated positions. Button 0 connected to GND controls relay 1 and button 1 connected to GND controls relay 2. See the image on the right how to configure this functionality in Tasmota.
