pyrmi

Very simple tool to send commands to a Corsair RMi/HXi PSU over USB and explore its returned values, thoughts, emotions and feelings.

Install

Quick and dirty

sudo pip3 install pyusb

or cleanly

python3 -m venv venv
source venv/bin/activate
pip3 install -r requirements.txt

Usage

See main.py or just try various things until you get what you're really looking for. Finding inner peace is one of the hidden features of this script.

sudo python3 main.py 03 8D
    hello RM650i
    raw bytearray(b'\xb7\xf0\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00')
