How to Collect Diagnostic Logs
If you experience any issues — TCP dropouts, inverter not polling, unexpected behavior — the BossMonitor Logger tool
lets you capture a detailed serial log directly from your device. This is the fastest way to help us diagnose
problems.
What you need:
- A Windows PC
- A USB cable connected from your PC to the BossMonitor device
- BossMonitor_Logger.exe from the Tools page
Steps:
1. Download BossMonitor_Logger.exe from https://gpineau.com/DIY-SOLAR/Tools/
2. Run it — no installation required
3. It will list available COM ports — select the one labeled USB Serial Device
4. Logs are saved automatically to a logs\ folder in the same directory as the exe
5. Let it run for at least 10–15 minutes while the issue is occurring
6. Zip the logs\ folder and attach it to your forum post
Log files created:
- raw_YYYY-MM-DD.log — everything
- events_YYYY-MM-DD.log — state changes (grid lost, TCP failures, SOC thresholds)
- diag_YYYY-MM-DD.log — detailed diagnostics and heartbeat entries
If you can reproduce the problem, the events log will usually show exactly what happened and when.
