dataskipper-boat 1.0.3

IEC61850/Modbus monitoring, control and data collection system

DataSkipper Boat

DataSkipper Boat is a Modbus monitoring application that reads data from Modbus devices, processes it, and sends measurements and alerts to various destinations.

Features

• Supports both Modbus TCP and Modbus RTU (Serial)
• Reads registers from multiple Modbus devices
• Processes measurements and checks for threshold violations
• Generates alerts for threshold violations and significant changes
• Stores measurements and alerts locally
• Sends measurements and alerts to API endpoints
• Sends alerts to Discord (and optionally other notification channels)
• Handles connection failures and retries

Installation

1. Clone the repository:

git clone https://github.com/yourusername/dataskipper-boat.git
cd dataskipper-boat

2. Install the dependencies:

pip install -r requirements.txt

Configuration

The application uses YAML configuration files located in the config directory:

• slave_config.yaml: Configuration for Modbus connections and devices
• communication.yaml: Configuration for API endpoints, MQTT, and notification channels

Environment Variables

• CONFIG_DIR: Path to the configuration directory (default: ~/config)
• DATA_DIR: Path to the data directory (default: ~/data)

Usage

To run the application:

python main.py

To reset water counters:

python reset_water_counter.py

Testing

The application includes unit tests and integration tests. See tests/README.md for more information on running the tests.

Modbus Server Simulator

A Modbus server simulator is included for testing and development. To run the simulator:

python run_modbus_simulator.py

By default, the simulator will start on localhost:5020. You can specify a different host and port using the --host and --port options:

python run_modbus_simulator.py --host 0.0.0.0 --port 502

Development

Adding a New Device

To add a new Modbus device:

1. Add a new client configuration to config/slave_config.yaml
2. Define the registers to read from the device
3. Configure thresholds and alerts as needed

Adding a New Notification Channel

To add a new notification channel:

1. Create a new notifier class in src/services/notifiers/
2. Implement the INotifier interface
3. Add the new notifier to the list of notifiers in main.py

Releasing a New Version

To release a new version of DataSkipper Boat:

1. Update version in pyproject.toml:

   # Edit pyproject.toml and increment the version number
   version = "1.0.1"  # or whatever the new version is
   

2. Build and upload to PyPI:

   # Build the package
   python -m build
   
   # Upload to PyPI (requires PyPI account and API token)
   python -m twine upload dist/*
   

3. Update target machines:

   # On each target machine, run:
   sudo -u dcu pip3 install --user --upgrade dataskipper-boat
   sudo supervisorctl restart dataskipper-boat-*:*
   

Setting Up a New Machine

To set up DataSkipper Boat on a new machine:

Prerequisites

• Python 3.8+ installed
• Supervisor installed (sudo apt install supervisor)
• PyPI access (internet connection)

Setup Steps

1. Install the application:

   # Install as user dcu (not root) to get correct paths
   sudo -u dcu pip3 install --user dataskipper-boat
   

2. Create user and directories:

   # Create user if it doesn't exist
   sudo useradd -m -s /bin/bash dcu
   
   # Create directories for each instance
   sudo mkdir -p /home/dcu/config_lt_panel /home/dcu/data_lt_panel
   sudo mkdir -p /home/dcu/config_ht_panel /home/dcu/data_ht_panel
   sudo mkdir -p /home/dcu/config_relay_panel /home/dcu/data_relay_panel
   sudo chown -R dcu:dcu /home/dcu/
   

3. Install supervisor config:

   # Copy supervisor config to target machine
   scp dataskipper-boat.conf target-machine:/tmp/
   
   # On target machine, install supervisor config
   sudo cp /tmp/dataskipper-boat.conf /etc/supervisor/conf.d/
   
   # Reload supervisor
   sudo supervisorctl reread
   sudo supervisorctl update
   

4. Copy your configuration files:

   # Copy your YAML config files to each instance directory:
   cp your_configs/slave_config.yaml /home/dcu/config_lt_panel/
   cp your_configs/communication.yaml /home/dcu/config_lt_panel/
   
   cp your_configs/slave_config.yaml /home/dcu/config_ht_panel/
   cp your_configs/communication.yaml /home/dcu/config_ht_panel/
   
   cp your_configs/slave_config.yaml /home/dcu/config_relay_panel/
   cp your_configs/communication.yaml /home/dcu/config_relay_panel/
   

5. Start the processes:

   sudo supervisorctl start dataskipper-boat-lt:*
   sudo supervisorctl start dataskipper-boat-ht:*
   sudo supervisorctl start dataskipper-boat-relay:*
   

6. Verify everything is working:

   # Check status
   sudo supervisorctl status
   
   # Check logs
   sudo supervisorctl tail -f dataskipper-boat-lt stderr
   

Useful Management Commands

• View status: sudo supervisorctl status
• Check logs: sudo supervisorctl tail -f dataskipper-boat-lt stderr
• Restart instance: sudo supervisorctl restart dataskipper-boat-lt:*
• Update application: sudo -u dcu pip3 install --user --upgrade dataskipper-boat && sudo supervisorctl restart dataskipper-boat-*:*
