esp-weather-station

Displays current weather data from open weather (https://openweathermap.org/) and your own sensor data from IotFreezer (https://iotfreezer.com/).

Adapted for 2.4in screen (I used ILI9341, for all supported options, see TFT_eSPI’s docs).

Uses the ArduinoJSON library for json parsing, TFT_eSPI for drawing on the screen.

Heavily inspired by https://github.com/Bodmer/OpenWeather. Built with platformIO.

The data above the line is from OpenWeatherMap, below the line is IotFreezer.

Components and prerequisites

ESP32 or ESP8266
TFT screen
An account on OpenWeatherMap, to get the API key
An account on IotFreezer and some sensor data uploaded to it

Usage

Before flashing, copy import_env.example.py to import_env.py and fill in your own configuration.

Make sure you upload the /data folder where the images and fonts reside to the ESP before flashing. You can do that with pio run --target uploadfs or just use the platformio addon for vscode and click on Upload Filesystem Image.

To generate a BMP that works with this repo, use image magick:
magick convert *.bmp -background black -alpha remove -compress none -depth 24 %d.bmp

Steps that follow

I also did some manual soldering work and 3d printed a case for it (slides into a wall mount, so you can easily flash and upgrade it):

The repository can be found at https://github.com/xtrinch/parametric-display-casing. It’s parametric, so you just measure the actual dimensions of your finished soldered product and enter them into the FreeCAD spreadsheet and print it.
