This instructable use ALEXA ECHO direct control ESP8266.

My server just support authorization ESP8266 to Amazon server.

My server do not backup your data.

Vote for me :D Thank you!

Step 1: Requirements

HARDWARE

ESP8266 WiFi 5V 1 Channel Relay Delay Module
https://www.amazon.com/WHDTS-ESP8266-Channel-Trans...
FTDI USB to serial module (not required if use nodemcu)
https://www.amazon.com/Qunqi-FT232RL-Serial-Adapter-Arduino/dp/B014Y1IMNM
Amazon Echo
Male and female power plug

SOFTWARE

· Arduino IDE with ESP8266 extension package installed guide here:
https://github.com/esp8266/arduino
My sketch here:
https://github.com/kim7tin/ESP8266-Smart-Power-Plug
My alexa skill named "ESP8266 Smart Power Plug"

Step 2: Flash New Frimware

1. Unplug ESP8266 from module

2.Connect module to USB to Uart module:

GND -------- | GND TX | -------- RX
------- | IO2 EN | -------- 3V3
GND ------- | IO0 RST | -------- BUTTON -------- GND
TX ------- | RX 3V3 | -------- 3V3

==================================================

BEFORE FLASH, PRESS BUTTON TO RESET
(IO0 alway connect to GND -> ESP8266 goto flash mode after reset)

==================================================

3.Flash my firmware

Download my sketch:
https://github.com/kim7tin/ESP8266-Smart-Power-Plu...
Open in Arduino IDE, and change:
- wifi_ssid: your wifi name
- wifi_password: your wifi password
- control_password: your secret password
- friendlyName: your device name
- ip/gateway/subnet: ESP8266 IP static for NAT
In Arduino IDE. Select Tool:
- Board: Node MCU 0.9 ()
- Upload Speed: 230400
- Port: Select your USB to Uart port
Hit Upload icon (before hit, press reset button in step 2)

4.Connect ESP to module again

5.Connect power plug

Step 3: Config NAT & DDNS

We need open port (default 666) to control from Amazon server to our ESP8266.

I just illustrated with my router. You can find out how to open your router port on the internet and open TCP port 666 to the configured ip in step 2

https://m.wikihow.com/Open-Ports

if you do not have a fixed ip. You must use a dynamic domain name. You can find many free DDNS service providers.

Step 4: Control by ALEXA ECHO

1.Enable my skill named "ESP8266 Smart Power Plug

Alexa app > Select menu > Skill
Search Skill named "ESP8266 Smart Power Plug"
Click to Skill
Click ENABLE
Login with your Static IP or DDNS domains (include your port - default 666)

2.Discover device

Alexa app > Select menu > SmartHome
Click Add device and wait 20 seconds
Now you can see ESP8266

3.Control:

"Alexa, turn on/off <your ESP named in step 2>"

Question 11 days ago

Also, what am I supposed to do with the three IP address sections, right in the beggining, I was confused as to what I should replace them with.

Question 11 days ago

How do I set it to activate just one of the pins? i looked at your code, but I couldn't figure it out. I just want to power GI00 or Gi02, not the relay. Could you help me?
