This is a single-channel WiFi switch relay module designed for high-power loads with a current rating of up to 20A. It empowers users to create their own wireless devices for remote appliance control. The module is adaptable, supporting various controller chips like EPS8266-12E, ESP-01, Qiachip, and ESP8266-12F.

Operating in AP+STA mode, the switch initially acts as an access point with the SSID name "HnHSwitch30" and uses "password" as the default password for connecting your smartphone via WiFi. Once connected, you'll be directed to a configuration page to input your WiFi credentials. After a restart, if you're on a laptop or phone, access the control page by typing "hnhswitch30.local" in your browser. From there, you can effortlessly manage your appliance within the local area network range using your smartphone or laptop. For remote control over the internet, reprogramming the device is necessary.This is a single-channel WiFi switch relay module designed for high-power loads with a current rating of up to 20A.
