## * 1. Self/Team Introduction

I am a self-taught embedded engineer who has served as a technical leader in many companies, mainly engaged in security and IoT related industries. I am a creative and persevering geek~

< br>
During 2019, I taught myself front-end, back-end, desktop, linux, python and other development knowledge at home, established the Yunzhe Innovation Team, and realized the Yunzhe Smart Home project. Yes, there is only me in the team at present, hahaha~

< br>
This is my personal website [Yunzhe Innovation](http://www.yunzhecx.cn/)

## * 2. Briefly introduce the project

This project is part of Yunzhe Smart Home. Due to the word limit of a single article and the content being too concentrated, which affects the viewing experience, it is divided into multiple projects, as follows

To discuss the project, you can scan the QR code to join the group and become a veteran. ![YunZhe Innovation Group Chat QR Code.png] # 【Please fill in during the competition↓】## * 1. Describe the project details. The name wall switch is because it is installed on the wall. Due to the power limit of the selected fuse and the lack of professional high-power load for testing, the power limit is 220W. ** When the load exceeds 220W, the fuse will blow! ** **Product features:** 1. Power 220W 2. 3-way touch button 3. 220V input 4. 433 reception 5.433 transmission 6. One-way relay control 7. Lora communication ## * 2. Describe the challenges faced by the project and the problems solved This work combines the functions of the touch panel and the light controller. It can be used as a panel to control other 433 devices, and can also be controlled by 433 signals. There are 3 touch buttons on the panel, 1 button controls its own relay, and the other 2 buttons control the output 433 signal. This work integrates the lora module while replacing the traditional 86 switch. It can realize network control with the gateway, and the integrated 433 transceiver function makes it more flexible to use. In one sentence, "I am a light controller that can control other light controllers". The Lora module of this work accounts for one-third of the cost, so in the future, the cost will be further reduced by designing other signal modules compatible with the size and pins of the lora module to reduce the cost. It will also consider directly connecting to the ESP8266 and other WiFi modules to connect to the gateway or skipping the gateway to directly connect to the backend. The overall direction can be summarized as low cost, high flexibility, high availability, and high stability. ## * 3. Describe the key points involved in the hardware and software parts of the project ### 3.1 Button description and settings of the wall switch 3.1.1. After the jumper cap is plugged in and the power is turned on, the functions of the three touch buttons are "remote control A on", "self relay control", and "remote control A off"; 3.1.2. After the jumper cap is removed, the functions of the three touch buttons are "remote control A anti-stop", "self relay control", and "remote control B anti-stop", which is equivalent to the control method of two independent 433 remote controls and one self relay. "Anti-stop" means the state is reversed or stopped. The state control depends on the controlled device. 3.1.3. After the jumper cap is plugged in, the three lights flash separately. When the middle light flashes, unplug the jumper cap to enter or exit the remote control learning mode. When the right light flashes, unplug the jumper cap to unbind the gateway. When the left light flashes, unplug the jumper cap to delete all paired remote controls. ### 3.2 Schematic diagram of wall switch wiring.
