ESP8266 WiFi 5V 1 Channel Relay Delay Module
FTDI USB to serial module (not required if use nodemcu)
- Amazon Echo
- Male and female power plug
- My sketch here:
- 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:
- 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
- Board: Node MCU 0.9 ()
- Upload Speed: 230400
- Port: Select your USB to Uart port
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
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)
Alexa app > Select menu > SmartHome
- Click Add device and wait 20 seconds
- Now you can see ESP8266
"Alexa, turn on/off <your ESP named in step 2>"
