Lilygo-T5 Rain graph

Weather precipitation graph using Lilygo T5 2.13" ESP32 E-paper screen. This project displays a precipitation forecast for the next 90 minutes using data from YR.no.

Hardware Requirements

• Lilygo T5 2.13" ESP32 E-paper display

Software Setup

1. Install the Arduino IDE from arduino.cc

2. Add ESP32 board support to Arduino IDE:

   • Open Arduino IDE
   • Go to File > Preferences
   • Add the following URL to the "Additional Boards Manager URLs" field: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   • Go to Tools > Board > Boards Manager
   • Search for "esp32" and install the "ESP32 by Espressif Systems" package

3. Install required libraries:

   • Download libs from https://github.com/Xinyuan-LilyGO/LilyGo-T5-Epaper-Series/tree/master/lib and put them in Documents\Arduino\libraries
   • Go to Sketch > Include Library > Manage Libraries
   • Search for and install the following libraries:
     • Time
     • ArduinoJson
     • WiFiManager
     • QRcodeDisplay
     • Preferences

4. Clone/download this repository and rename the folder yr-regn-display

5. Create a config.h file in the same directory as yr-regn-display.ino based on the example.config.h file

6. Open the yr-regn-display.ino file in Arduino IDE

7. Customize your configuration:

   • In the config.h file:
     • Modify the USER_AGENT if desired
     • Set DEBUG to true or false as needed
     • set SHOW_GRAPH_ON_NO_PRECIPITATION to liking
     • set SHOW_BATTERY_INDICATOR to liking

8. Select the correct board and port:

   • Go to Tools > Board and select "ESP32 Dev Module" or your specific Lilygo T5 board
   • Go to Tools > Port and select the appropriate port for your device

9. Upload the sketch to your Lilygo T5 device

Usage

Once uploaded, the device will prompt you to connect to Wi-Fi. Once connected, it will fetch precipitation data from YR.no, and display a graph showing the precipitation forecast for the next 90 minutes.
