This guide provides a comprehensive walkthrough for setting up and utilizing a smart switch with the Tuya IoT platform. It is designed for individuals looking to explore IoT solutions for smart home automation, similar to platforms like Blynk and RemoteMe.
Project Overview
The project involves integrating hardware components like the Arduino UNO Rev 3 and Wemos D1 Mini with the Tuya IoT platform to create a functional smart switch. This process includes device creation on the Tuya platform, firmware burning onto the ESP8266 module, programming the Arduino, and finally, configuring the Tuya Smart app for control.
Supplies Needed
Hardware Requirements:
- Arduino UNO Rev 3
- Wemos D1 Mini (ESP8266 based)
- Breadboard Kit
Software Requirements:
- Arduino IDE
- Tuya account
- Active Internet Connection
Key Steps
Step 1: Making a Device on Tuya
Create an account on Tuya.com. Navigate the platform to create a new device, selecting 'Electrical' then 'Switch' under the 'Custom solution'. Fill in product details like name and protocol (e.g., WiFi for ESP8266). Obtain a token by emailing PID details to dev@tuya.com.
Step 2: Activation on Tuya PMS
Log in to the Tuya PMS site. Navigate to 'Production Management' >> 'Work Order Management' >> 'Activation Code Verification'. Paste the obtained token and confirm to register the device. Download the TYDA app for firmware burning.
Step 3: Burning Firmware on ESP8266
Install the CP210x driver and the TYDA application. Connect the Wemos D1 Mini (ESP8266) to the PC via USB. Select the correct COM port in the TYDA app, enter the token, and initiate the firmware burning process. The TYDA app interface will indicate completion.
Step 4: Programming the Arduino
Download and install the Arduino IDE. Install the 'Tuya' library via the Library Manager. Open the 'Tuya_WiFi_MCU_SDK' example sketch. Connect the Arduino UNO to the PC, select the correct port, and upload the sketch. Ensure the CH341 USB driver is installed if using a clone board.
Step 5: Connections
Connect the ESP8266 module and the Arduino UNO using jumper wires according to the provided diagram. Ensure boards are disconnected before making connections.
Step 6: Making the App
Download the 'Tuya Smart' app from the Play Store or App Store. Add a new device, select 'Switch (Wi-Fi)', and enter Wi-Fi credentials (2.4GHz network required). Put the ESP8266 into pairing mode by connecting Pin 7 to GND for 3-4 seconds. Follow the app prompts to complete the device pairing.
Step 7: Testing and Conclusion
The smart switch should now be functional and controllable via the Tuya Smart app. The project can be extended by replacing the LED with a relay to control appliances.
