ESP8285 Relay Controller V2.0

The WIFI relay developed based on ESP8285 uses the MQTT communication protocol. The protocol content can be customized, and the MQTT server address and user can be configured by logging into the device's web management backend.

1. Equipment Description
1.1 Appearance
1.2 Power Supply:
100~240V AC input, Lin connects to the live wire, Nin connects to the neutral wire.
1.3 Load Connection:
    The output signal is a passive relay signal, used for signal on/off control. It can handle a maximum load current of 10A. COM is the relay common terminal, NO is the relay normally open terminal, and the default state upon power-on is off.
1.4 Indicator Light Status Description:
There are three LED indicators: red, green, and blue. The corresponding device states are as follows:
Red light flashing rapidly: Waiting for network configuration Red light flashing slowly: Connected to the router, connecting to the MQTT server; Red light on: Connected to the MQTT server;
Blue light flashing once: Button pressed for more than 5 seconds;
Green light on: Relay on;
Green light off: Relay off.
1.5 Button Operation
: Short press for 1 second and release: Switch relay state;
Long press for 5 seconds: Device enters network configuration mode.
2. Function Operation
2.1 Connecting to the Wi-Fi router
requires using a mobile phone to run network configuration software. First, install the esptouch software on your phone. It only supports Android systems. Software download link: https://github.com/EspressifApp/EsptouchForAndroid/releases/tag/v2.0.0/esptouch-v2.0.0.apk
The network configuration steps are as follows:
Power on the device;
Press and hold the button for 5 seconds (release after the blue light flashes rapidly). At this time, the device enters network configuration mode;
Connect the phone to the router;
Launch the esptouch software on the phone and select EspTouch;
Enter the router password in the password box and then click confirm;
After successful network configuration, the EspTouch software will display the device's BSSID (MAC) and the LAN IP address assigned to the device by the router. You need to record the IP address for logging into the device's web management backend.
2.2 Web Management Backend
2.2.1 Login
Launch a mobile phone or computer browser on the same local area network. Enter the current device's IP address in the address bar, such as 192.168.10.103, and click to enter:
Username: admin
Default password: 123456
2.2.2 Change login password
Select the "USER" option in the directory bar:
2.2.3 Configure MQTT server
Select the "MQTT" option in the directory bar:
The default server HOST: broker.emqx.io, port: 1883, is a free MQTT server that can be used for testing.
2.2.4 View device information
Select the "DEVICE" option in the directory bar:
