Install requirement

Install Arduino IDE and install esp8266 additional board manager as explained here.

Flash code

Following the minimal hardware setup for bootloading explaining here and using a 3.3V USB To Serial adapter, you should be able to flash the following code to your esp8266 : https://github.com/paulgreg/internet-smart-plug

Please note that USB serial adapater ground need to be connected to ESP8266’s power adapter ground.

You’ll need to copy/paste parameters.h.dist to parameters.h and change your configuration information.

Beware, esp8266 don’t support 5V so be sure to use a power supply and an USB serial adapter which operates at 3.3V !
Doing otherwise will simply destroy your module.

Run the code

To test your code, you’ll need to

• disconnect the RST / reset pin
• connect GPIO0 to pullup (instead of GND) as explained here,
• connect GPIO16 (or XPD) to RST pin to allow deepsleep as explained here.

Opening the serial monitor from arduino, you should be able to view some messages from esp8266.
