How the Victron Monitoring Application Was Built

A Deep Dive into the Python Code

1. Application Structure

The app uses PyQt6 for the GUI, with these key components:

• Main Window (VictronMonitor class) – Handles tabs, timers, and configurations.
• API Communication (get_victron_data()) – Fetches data from Victron VRM.
• Alert System (check_alarm()) – Monitors thresholds and triggers warnings.

2. Key Functions

• Authentication – Logs into Victron API using user credentials.
• Data Parsing – Extracts battery SOC, voltage, power, etc.
• Email Notifications – Uses smtplib to send alerts.

3. Configuration Management

Settings are stored in config.json, including:

• Victron credentials
• Alarm thresholds
• SMTP email settings

4. Error Handling & Logging

• Try-Except Blocks – Prevent crashes from API failures.
• Logging Module – Records errors and status updates.

I think this application demonstrates how Python can be used to build powerful monitoring tools for energy systems.
