XVGU Signal Tower Controller

This project provides a Python-based tool (CLI + GUI) for controlling Schneider Electric Pro-face XVGU3SHAG and XVGU3SWG USB signal towers from a Raspberry Pi.

Tested on: Raspberry Pi 5 with Raspberry Pi OS 64-bit
Compatible devices: XVGU3SHAG, XVGU3SWG
⚠️ This project is an independent implementation and not affiliated with Schneider Electric.

Installation and Usage (Raspberry Pi 5)

1. Connect the device

Plug the XVGU signal tower into a USB port on your Raspberry Pi.

2. Install dependencies

sudo apt update
sudo apt install -y python3-tk libusb-1.0-0 python3-pip
pip3 install pyusb

3. Set up USB permissions

sudo cp 99-xvgu.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules
sudo udevadm trigger

Then unplug and reconnect the XVGU device.

4. Run a test (CLI)

# Turn on red on layer ONE
python3 xvgu.py ledset --layer ONE --name red --pattern ON

# Start buzzer (default: tone=high, volume=mid)
python3 xvgu.py buzzer

# Start buzzer with custom tone and volume
python3 xvgu.py buzzer --tone high --volume big --seconds 2

# Stop buzzer
python3 xvgu.py buzzer --off

5. Launch the GUI

python3 xvgu_gui.py

This opens a graphical interface to control lights and buzzer.
