hues

A Rust client for the Philips Hue API v2, with a focus on accuracy to the official spec.

hues uses reqwest and the tokio async runtime. It currently supports most basic operations, such as:

• Local network device discovery
  • Via mDNS using the mdns crate, requires the mdns feature
  • Via HTTPS using the Hue Discovery Endpoint
• App key creation
• Light, Group, and Scene control
• Schedule and Smart Scene management

It does not yet support the following features:

• Entertainment API for fast, synchronous light effects via UDP
• Advanced features regarding Entertainment Configurations

[!WARNING] This is an experimental library, and is subject to change. Use at your own risk.

Installation

cargo add hues

Usage

If you already know your Bridge IP address and have previously created an App Key, constructing a client is quick and simple:

use hues::prelude::*;

#[tokio::main]
async fn main() -> Result<(), HueAPIError> {
    // Construct a Bridge when IP and App Key are known
    let bridge = Bridge::new([10u8, 0, 0, 123], "my-app-key");
    // Refresh it to fetch the current state of all resources
    bridge.refresh().await?;
    
    // Toggle the power state of a Room named "office", if it exists
    if let Some(office) = bridge.rooms().iter().find(|r| r.name() == "office") {
        office.toggle().await?;
    }
    Ok(())
}

Bridge discovery and registration

When the Bridge IP address is not known, you can locate the device on the local network using the Bridge::discover associated function. If you are creating an app for the first time, the Bridge::create_app method initializes new credentials that can be used for future authentication.

use hues::prelude::*
use std::time::Duration;

#[tokio::main]
async fn main() {
    // Discover a Hue Bridge on the local network, and initialize polling
    // to synchronize state every 30 seconds.
    let mut bridge = Bridge::discover()
        .await
        .unwrap()
        .build()
        .poll(Duration::from_secs(30))
        .await;
    // This is your App Key, it should be saved for future sessions
    // NOTE: press the `Link Button` on the Hues Bridge before attempting
    // to create new app credentials.
    let key = bridge.create_app("my_app", "my_instance").await.unwrap();

    // Blink each light to confirm you're registered!
    for light in bridge.lights() {
        let _ = light.identify().await;
    }
}

Automatic sync with sse

Optionally, you can sync automatically by listening for Server-Sent Events. The bridge will communicate changes as they happen to the client, and you can take action if you choose to do so:

use hues::prelude::*;

#[tokio::main]
async main() -> Result<(), HueAPIError> {
    let bridge = Bridge::new([10u8, 0, 0, 123], "my_app_key").listen(|_rids| {
        // Do something whenever changes are sent from the Bridge
    });
}
