Instructions for use Working mode 1 (mobile phone is installed on the ESP-01 module) Step 1: Plug in the ESP-01 module, and the module is powered on. After about 4 seconds, the green light changes from off to 2S slow flashing, indicating that the configuration is complete Step 2: Connect the mobile phone to the AP hotspot signal sent by the ESP-01 module Step 3: Open the "EasyTCP_20" APP, click "CONNECT", enter the IP address: 192.168.4.1 and port number 8080, and then click "Connect" Step 4: After the connection is successful, the green light will change from 2 seconds slow flash to constant light. Click the gray box to send instructions to control the switch of the relay Working mode 2 (mobile phone and ESP-01 module are installed on the router at the same time) Step 1: Plug in the ESP-01 module, power on the module, wait until the green light changes to slow flashing, and then press the S1 key to switch to mode 2. The blue light turns on. After about 1 minute, the green light changes from off to 0.5S fast flashing, which means waiting for the "EspTouch_ Demo" APP to configure its WIF account and password Step 2: Connect the phone to the router and open "EspTouch_ Demo "APP, enter the router password, and click "Confirm" Step 3: Wait for the configuration to succeed. When the IP address of ESP-01 (such as 192.168.0.189) appears on the APP interface, it indicates that the ESP-01 module has successfully connected to the router, and automatically memorizes the account and password. The next time you enter Mode 2, it will automatically connect (about 20-60S can be connected) Step 4: Open the "EasyTCP_20" APP, click "CONNECT", enter the IP address: 192.168.0.189 and port number 8080, and then click "Connect"

Complete the configuration of the ESP-01WIFl module account and password on the mobile phone APP. The configured account and password have the power-off memory function. The 5V ESP8266 dual-way WIFI relay module uses ESP-01 as the WIFI module, and with mature and stable 8-bit MCU chip, it only needs a simple configuration process to realize wireless control of the two-way relay in the LAN using mobile phone APP. On-board 5V, 10A/250V AC 10A/30V DC relay, which can be continuously closed for 100000 times, has diode leakage protection and short response time; On-board mode selection and real-time working status indicator; UART debugging interface and MCU SWIM program download interface are reserved. The module has two working modes, and only one WIFI is required for wireless control, Mode 1: The mobile phone is directly mounted on the WIFI module; Mode 2: On the router that the mobile phone and the WIFI module are carried at the same time. Realize wireless control of mobile phone, switch on and off anytime and anywhere. In an open environment, the maximum stable transmission distance of the mobile phone is 100m when it is carried on the WIFI module; When the WIFI module and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router.
