# Home Assistant Logger
This script connects to a Home Assistant instance, fetches temperature and humidity data, stores it, and generates an HTML report.
## Prerequisites
- Docker
## How to Use
### 1. Build the Docker Image
```bash
docker build -t ha-logger .
```
### 2. Run the Docker Container
You need to provide your Home Assistant URL and a Long-Lived Access Token as environment variables.
```bash
docker run --rm -v $(pwd):/app
-e HA_URL="http://your-home-assistant-ip:8123"
-e HA_TOKEN="your-long-lived-access-token"
ha-logger
```
- Replace `"http://your-home-assistant-ip:8123"` with the URL of your Home Assistant instance.
- Replace `"your-long-lived-access-token"` with your token.
The `-v $(pwd):/app` command mounts the current directory into the container, so the output files (`index.html` and `sensor_data.json`) are created and updated in your project folder.
### How it Works
- The script connects to your Home Assistant instance using the provided URL and token.
- It fetches all devices and filters for sensors that have a unit of `°C` (Celsius) or `%` (for humidity).
- The new readings are appended to the `sensor_data.json` file.
- An `index.html` file is generated, displaying the latest readings and a searchable, sortable history of all readings.
### Generated Files
- **`sensor_data.json`**: Stores the historical data for all sensor readings.
- **`index.html`**: The generated HTML report. Open this file in your browser to see the sensor data.
