# printstats

A printer monitoring service that aggregates status from multiple 3D printers (Prusa and Bambu) and exposes them through a unified HTTP API.

## Features

- Monitor Prusa and Bambu 3D printers simultaneously
- Prusa: polls via HTTP REST API every 5 seconds
- Bambu: real-time updates via MQTT subscription
- Unified JSON endpoint for all printer states
- Tracks bed temperature and print status per printer

## Prerequisites

- Rust
- Network connectivity to your printers

## Setup

1. Copy the example config and fill in your printer details:
   ```sh
   cp example_config.toml config.toml
   ```

2. Edit `config.toml`:
   ```toml
   [[printers]]
   type = "prusa"
   name = "MyPrusa"
   host = "192.168.1.10"
   api_key = "your-api-key"

   [[printers]]
   type = "bambu"
   name = "MyBambu"
   host = "192.168.1.11"
   access_code = "12345678"
   serial_number = "ABCDEFGH"
   ```

## Build & Run

```sh
cargo build --release
./target/release/printstats
```

Or directly:

```sh
cargo run
```

The server listens on `0.0.0.0:3000`.

## API

### `GET /`

Returns the current state of all configured printers.

**Response:**
```json
{
  "MyPrusa": {
    "bed_temp": 60.0,
    "status": "Printing"
  },
  "MyBambu": {
    "bed_temp": 0.0,
    "status": "Idle"
  }
}
```

**Status values:** `Idle`, `Printing`, `Paused`, `Finished`, `Unknown`

## Logging

Uses the `tracing` crate. Control log level via `RUST_LOG`:

```sh
RUST_LOG=debug cargo run
```
