WiFi switch box

The screw hole spacing is suitable for common 86, 118, and 120 switch boxes, i.e., 60mm and 83-86mm. The switch box requires a neutral wire;
3D printing uses at least 15% filler. The off support
button uses a 30mm stainless steel button, similar to an elevator button. The button vibrates quite severely, so the debounce time is set to be relatively long. The button has an indicator light, which can be set to always on, always off, or in automatic mode (indicator off when relay is on, indicator on when relay is off).
The controller uses AI-WB2-01S, which the seller claims has passed a 1000-hour test in an 85°C, 85% humidity environment, but the development environment is not very friendly.
There is a small cooling fan with a 40°C temperature switch connected in series. Normally, the fan is difficult to turn on, but it should be useful in hot weather. The 5V power supply is from the WIFI switch module.
The 4-pin connector of the WIFI switch module leads to two GPIOs, 3.3V, and GND for connecting to the button panel. One is for button interruption, and the other controls the indicator light on the button.
The Android APP uses Android... The software was developed using a software development platform (SDK), the PC app is written in Python, and the microcontroller uses the official SDK provided by Anxinke and the Eclipse IDE. It lacks automatic network configuration; you need to manually input your Wi-Fi name, password, IP address, and port number into the source code. Therefore, the
