Introduction

Relays are one of the most commonly used components for setting the smart home when we are doing the Internet of Things.
For wireless control, we specially designed this relay module. The relay module is equipped with an ESP8266-01 Wifi module.
It can be connected to the wireless network, and then can send commands to the module in the remote or LAN host computer. After receiving the command, the module can close or open the relay.

For simple use, we provide our own compiled firmware, the firmware is server mode.
