Inky Pi

Inky_pi is a project to display train and weather data on an Inky e-ink display using a Raspberry Pi. It is modular and fetches data from a variety of sources (OpenLDBWS, Huxley2, OpenWeatherMap).

Weather icon drawing code was adapted from raspi-weather.

Project setup was aided using Sam Brigg's cookiecutter template fork.

Installation

Use the Poetry package manager to install Inky_pi.

poetry install

Usage

poetry shell
inky_pi display --help

Alternatively, the program can be called via its main function.

poetry shell
python -m inky_pi --help

The program can be configured by running python -m inky_web to launch the configuration editor web interface. The web interface creates/edits the local .env file which holds application configuration.

API keys for configuration are needed for train data using OpenLDBWS and for weather data using OpenWeatherMap. Alternatively, train data can be fetched using Huxley2 without an API key (though the maintainer contends that the Huxley2 server goes down often without notice). A module for Weather Underground could be easily written as a contribution/exercise.

The program runs once per invocation. For automated scheduling, cron is recommended using the python main.py invocation as described above.
