- # MQTT Configuration
-
- This project can publish weather and public transport data to an MQTT broker.
- To enable MQTT, follow these steps:
-
- ## 1. Install dependencies
- Ensure you have Rust and Cargo installed. The MQTT support uses the Paho MQTT client crate.
- Run:
- ```bash
- cargo update
- ```
-
- ## 2. Set the MQTT_BROKER environment variable
- Before running the client, define `MQTT_BROKER` to your broker address.
- - Without URI scheme (defaults to TCP):
-   ```bash
-   export MQTT_BROKER=localhost:1883
-   ```
- - With URI scheme:
-   ```bash
-   export MQTT_BROKER=tcp://broker.example.com:1883
-   ```
-
- ## 3. Run the LED board client
- Pass the LED board IP address as the only argument:
- ```bash
- export MQTT_BROKER=localhost:1883
- cargo run --bin ledboard_client -- 192.168.1.50
- ```
-
- ## Topics and Payloads
- The client publishes two topics:
-
- ### weather
- JSON payload with fields:
- - `dt`: timestamp (Unix seconds)
- - `temp`: temperature in °C
- - `weather`: object with `main`, `description`, `icon`
- - `rain`: rain volume in last 3h (optional)
- - `pop`: probability of precipitation
- - `wind`: object with `speed`, `deg`, `gust`
-
- ### straba
- JSON payload with fields:
- - `outbound_station`: name of outbound station
- - `outbound_diff`: seconds until outbound departure
- - `inbound_station`: name of inbound station
- - `inbound_diff`: seconds until inbound departure
-
- ## Customization
- You can adjust MQTT topics, QoS, and message formats in `client/bin/src/main.rs` under the `publish_to_mqtt` function.
