Possible Causes

Incorrect time or timezone set, Overlapping or disabled schedules, Vehicle also using its own schedule conflicting with charger, RTC drift without backup battery

How to Fix / Troubleshooting

Safety first: This is a control issue, not typically an electrical hazard.

  • 1. Verify time:
    • Check the charger’s internal clock and timezone settings.
    • Correct them if inaccurate.
  • 2. Review schedules:
    • In the app or web interface, review all active schedules.
    • Ensure they are enabled and not overlapping in a way that cancels charging.
  • 3. Check vehicle settings:
    • Disable the vehicle’s own charging schedule temporarily to avoid conflicts.
  • 4. Test a simple schedule:
    • Create a single, clear time window and observe if charging starts.
  • 5. Firmware update:
    • Update charger firmware if scheduling bugs are known and fixed in newer versions.
