RiseMode Driver

An experimental Rust driver for the Rise Mode Aura Ice Black water cooler with temperature display.

Overview

This driver reads CPU temperature from your system and sends it to the Rise Mode Aura Ice Black water cooler's integrated display. The driver communicates with the display via USB HID protocol.

Features

• Real-time CPU temperature monitoring
• Automatic device detection and connection
• Continuous temperature updates (1 second interval)
• Automatic reconnection on device disconnect

Compatibility

✅ Linux

Fully supported. Reads CPU temperature from:

• /sys/class/hwmon/ (coretemp, k10temp, zenpower)
• /sys/class/thermal/ (thermal zones)

❌ Windows

Currently NOT supported. Temperature reading requires Linux-specific sysfs paths. The HID communication would work, but temperature reading needs to be implemented using Windows APIs or the sysinfo crate.

Requirements

• Rust 1.70 or later
• Rise Mode Aura Ice Black water cooler connected via USB
• Linux operating system (for temperature reading)
• Appropriate permissions to access HID devices (see below)

Installation

1. Clone the repository

git clone https://github.com/evozniak/risemode-driver.git
cd risemode-driver

2. Build the project

cargo build --release

The compiled binary will be located at target/release/risemode-driver.

Usage

Running the driver

cargo run --release

Or run the compiled binary directly:

./target/release/risemode-driver

Linux Permissions

On Linux, you may need to run with sudo or configure udev rules to access HID devices:

sudo ./target/release/risemode-driver

Setting up udev rules (recommended)

Create a udev rule file to allow non-root access:

sudo nano /etc/udev/rules.d/99-risemode.rules

Add the following line (replace YOUR_USERNAME with your actual username):

SUBSYSTEM=="hidraw", ATTRS{idVendor}=="aa88", ATTRS{idProduct}=="8666", MODE="0666", GROUP="YOUR_USERNAME"

Reload udev rules:

sudo udevadm control --reload-rules
sudo udevadm trigger

Device Information

• Vendor ID: 0xaa88 (43656)
• Product ID: 0x8666 (34406)
• Communication: USB HID
• Update Rate: 1 Hz (every second)

Output

The driver displays real-time information:

SendTemp (Rust version) - Starting...
Reading CPU temperature and sending to water cooler display

Development

Building for development

cargo build

Running with debug output

RUST_LOG=debug cargo run

Technical Details

The driver sends temperature data in a 24-byte buffer format:

• Byte 0: Integer part of temperature (°C)
• Byte 1: First decimal digit (0-9)
• Bytes 2-23: Padding (zeros)

Troubleshooting

Device not found

• Ensure the Rise Mode Aura Ice Black is properly connected via USB
• Check if the device appears in lsusb output
• Verify vendor/product IDs match: lsusb | grep aa88:8666

Permission denied

• Run with sudo or set up udev rules (see Usage section)

No temperature readings

• Verify CPU temperature sensors are available: ls /sys/class/hwmon/*/temp*_input
• Check thermal zones: ls /sys/class/thermal/thermal_zone*/temp
