The glow-control-lib
crate is a Rust library designed to interface with Twinkly LED devices. It provides a
comprehensive set of APIs that facilitate the discovery of devices, manipulation of device modes, control of real-time
lighting effects, and more. This library serves as the backbone for the glow-control
CLI and can be used to build
custom applications that manage Twinkly LED controllers.
This project draws inspiration from the Python libraries xled and xled_plus, and it is intended to be an open-source alternative for the Rust ecosystem.
A simple example of how to use the library to set Twinkly devices to a specific mode:
use std::collections::HashSet;
use std::time::Duration;
use glow_control_lib::control_interface::{ControlInterface, DeviceMode};
use glow_control_lib::util::discovery::{DeviceIdentifier, Discovery};
use serde_json::json;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Discover devices with a 5-second timeout
let devices: HashSet<DeviceIdentifier> = Discovery::find_devices(Duration::from_secs(5)).await?;
// Iterate over the discovered devices, print their details and set their mode
for device in devices {
println!("\n{} Found device {}\n{:?}\n", "=".repeat(30), "=".repeat(30), device);
let control = ControlInterface::from_device_identifier(device).await?;
control.set_mode(DeviceMode::Color).await?;
}
Ok(())

For more examples and detailed API documentation, run cargo doc --open
after adding the library to your project.
To install the CLI application, ensure you have Rust and Cargo installed, then run:
cargo install glow-control
to install from crates-io, or:
cargo install --path .
to install directly from the repository.
To get started, make sure your lights have been configured on your local network using the official Twinkly app, and
that you have used the app to generate a 3D point cloud. This point cloud will be stored on your individual Twinkly
devices by the official app, so after initial configuration, you no longer need the app to use glow-control
.
The glow-control
CLI provides a discover
subcommand that allows you to scan your network for Twinkly devices. You
can use this feature to find the IP and MAC addresses of your devices, which are required for other CLI commands.
To use the discover
feature, run the following command:
The discovery search time is 5000ms by default. You can adjust it if needed.
glow-control discover
IP Address Device ID MAC Address Device Name LED Count
----------- -------------- ----------------- ----------- ---------
10.10.0.42 Twinkly_C54ABC 11:38:aa:c4:aa:55 Living Room 250
10.10.0.37 Twinkly_C5CDEF bb:e5:7c:dd:bb:57 Kitchen 600
You can also specify the output format using the --output
option. Supported formats are:
plaintext
(default)json
yaml
For example, to get the results in JSON format:
glow-control discover --output json
To run the real-time test colors, use the real-time-test
subcommand under the device-call
command. This will display
a rotating color pattern on Twinkly device.
glow-control device-call --ip <DEVICE_IP> --mac <DEVICE_MAC> real-time-test
<DEVICE_IP>
and <DEVICE_MAC>
are the IP and MAC addresses of your Twinkly device, respectively. They must be
specified for all device-specific commands.
The real-time test inputs frames directly from the CLI binary. Once you terminate the program, the Twinkly device will eventually timeout and return to its previous state.
Integration with other applications is possible by piping the output of another program to the CLI. For example, to display random, changing colors on a device:
cat /dev/random| cargo run -- device-call --ip 10.10.0.37 --mac bb:e5:7c:dd:bb:57 rt-stdin --format binary --error-mode mod-invalid-address --leds-per-frame 5 --min-frame-duration 100
Set the device mode to 'movie':
glow-control device-call --ip <DEVICE_IP> --mac <DEVICE_MAC> set-mode movie
Show a solid color:
glow-control device-call --ip <DEVICE_IP> --mac <DEVICE_MAC> rt-effect show-color --color Red
