I didn't spot any headers, but device has a sub-board with an ESP-12 module on it. Solder right to the 3.3V, Ground, TX, RX, and GPIO pins and flash away. I set the device up as a generic device with the following assignments.

  • GPIO 3 is button 2
  • GPIO 4 is relay 2
  • GPIO 12 is button 1
  • GPIO 13 is relay 1
