# TRMNL Weather & Pollen Report
|
||||
|
||||
A custom TRMNL plugin that fetches and displays weather and pollen data.
|
||||
|
||||
## Setup
|
||||
|
||||
1. Set up a virtual environment and install dependencies:
|
||||
```bash
|
||||
python -m venv .venv
|
||||
source .venv/bin/activate
|
||||
uv sync
|
||||
```
|
||||
|
||||
2. Set required environment variables:
|
||||
```bash
|
||||
export WEATHER_API_KEY="your_openweathermap_api_key"
|
||||
export AUTH_TOKEN="your_chosen_auth_token"
|
||||
```
|
||||
|
||||
3. Run the application:
|
||||
```bash
|
||||
fastapi run main.py --port 8887
|
||||
```
|
||||
|
||||
## Docker
|
||||
|
||||
Build and run with Docker:
|
||||
```bash
|
||||
docker build -t trmnl-report .
|
||||
docker run -p 8887:8887 -e WEATHER_API_KEY=your_key -e AUTH_TOKEN=your_token trmnl-report
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
Access the API at `http://localhost:8887/?token=your_auth_token`
