Online Tuya Devices Manager for Cheap Yellow Display (CYD) boards.

(Tested and Running on the ESP32 2432S024Rv3)

This is a basic device manager for all kinds of devices connected to the Tuya cloud via e.g. the Smart Life app. I use it to display the status for my door, window, socket and temperature sensors.

Developed with Visual Studio Code and PlatformIO

Warning

Still very much work-in-progress! There is no error handling for now.

Credits go to Rzeldent's esp32-smartdisplay without I would never have been able to set this up so quickly.

Features

• Fetches all devices from the Tuya cloud connected to the clientID
• For each device ID, fetch the current device status
• If the device type matches one of the declarations in the ui_globals.cpp, parse and display the infos
  • Don't forget to also add new devices types to the parsing function updateDevicesDisplay() in ui.cpp

Requirements for running

• A clientID and clientSecret are needed -> they are obtainable in the Tuya cloud at cloud->project->Overview (https://platform.tuya.com/cloud/basic)
  • (The account might need to be set as a dev account, but I forgot where exactly this can be set ;))

Setup

1. Clone this repository (all sub modules will automatically be cloned by platformIO)
2. Copy config_template.h to config.h
3. Edit config.h and fill in your personal information:
   • WiFi SSID and password
   • Tuya client ID and secret
4. Set your Arduino board in the platformio.ini
5. Compile and upload the project to your Arduino board
6. Happy coding!

Note: config.h is ignored by git to keep your personal information private.

Note #2: The method updateTimeOffset() in main.cpp only works for CET, it needs to be adjusted for other timezones for the clock and api calls to work correctly.
