Wallbox Monitor

A Python script for monitoring a local wallbox charging station from NewMotion / Shell Recharge and sending notifications via Discord.

Features

• Reads charging rate and consumed energy from a web-based wallbox interface.
• Uses Selenium to extract data dynamically.
• Sends notifications to Discord when charging starts, stops, and after 5 minutes: charging rate.
• Sends a notification to Discord after charging stopped, summarizing consumed energy and time.
• Sends a notification to Discord when the cable was connected or disconnected.
• Prevents false positives by only detecting charging above 1.0 kW.
• Handles missing values gracefully.

Check logs in:

cat /home/pi/wallbox-monitor/wallbox_monitor.log

🛠 Troubleshooting

Selenium Fails: “NoSuchDriverException”

Try reinstalling chromedriver:

sudo apt install --reinstall chromium-chromedriver

Charging or Consumed Energy Not Detected

Run debug script:

python3 test_consumed_debug.py
