This is WiFi relay module based on the ESP8266 serial module. And it controls the relay working status through the APP. Perfect kit for controlling all your household appliances with your phone wherever you are.

Method of application:

1. ESP8266 WIFI module has three operating modes: STA, AP and STA + AP.

You can choose the operating mode according to the working mode of the module.

2. Before you use the module, you need to use the serial debugging software and USB to TTL module to send serial port command to configure the WIFI module. And please connect the RX/TX/GND pins of USB to TTL module to the module’s RX/TX/GND pins.

(The default baud rate of the ESP8266 module is 115200 or 9600. When it’s 115200, you need to send AT + CIOBAUD = 9600 and set the baud rate as 9600, otherwise the relay can not be properly controlled). And connect the IN +, IN- to the 5V power supply.

3. After the configuration is completed, please install the “EasyTCP_20” APP on the Android phone. Then click “Connection” and ” Open”. Please be noted that the 5V power supply cannot be off, or some parameters of the WIFI module will miss.

Then press the column in grey in the interface for entering the serial command, the command name and content(open the relay module when the content is A00101A2, while close the relay when it’s A00100A1).

Please send the commend in the form of hexadecimal. And you can control the on/off of the relay module by clicking the related columns.
