Introduction: Simple WiFi Remote Control Socket With ESP8266

Picture of Simple WiFi Remote Control Socket With ESP8266

This project demonstrate how to make very simple WiFi remote control socket. It is based on ESP8266 dev kit and H34A 433Mhz transmitter. In additional you need radio controlled socket available in market.

Device works in 3 modes:

1) Connect to your WiFi infrastructure: if first time or no known network found starts as WiFi Access Point to chose WiFi network, after your chose it will connect to your network and work as WiFi device with IP addres from your DHCP server (usualy router). In this case no pin is grounded.

2) If pin D3 is grounded starts as AP to chose network again, then works like mode 1. It is for cases when you want to change known network.

3) If pin D2 is grounded works as standalone WiFi Access Point.

This project demonstrate autonomous clock switch with two settable times per day to switch socket on to desired duration. Time in device is set from public NTP server.

Another possibility is control device manually via web browser from phone on computer or automatically from other device by HTTP request. Every request has to be authenticate.

ESP8266 ..... H34A

G .................. GND

3V ................ VCC

D5 ............... DATA

D2 ............... if grounded works as WiFi AP

D3 ............... if grounded reconfigure WiFi network

Step 4: Screenshots

Picture of Screenshots

Web pages screenshots from mobile phone browser connected to ESP8266 web server.

Step 5: HTTP Requests

Device can be controlled via HTTP request with following format:
http://?id=&cmd=
where is device IP address, id is socket id 0 to 3 and CMD is on, off or auto.

For example http://192.168.4.1?id=0&cmd=on switch socket 0 on. First time authorization request will be shown to prevent unauthorized access.

For control from another wget can be used:

wget http://192.168.4.1?id=0&cmd=on --user=admin --password=esp8266

Step 6: How to Learn Remote Control Code

Picture of How to Learn Remote Control Code

If you have another remote control socket with unknown code you can learn it.

Connect RF receiver to Arduino, and use following sketch to listen. Then copy captured code from Serial Monitor to main code into variables: byte rf1off[], byte rf1on[] and so on.

RX pin of reciever is connected to A0 arduino pin.
