Possible Causes

Note: This is usually a configuration or firmware issue, not a hardware failure.

  • Verify date and time: Use the app or web interface to check that the wallbox clock and timezone are correct.
  • Recreate schedules: Delete existing schedules and recreate them carefully, ensuring correct days and start/end times.
  • Check app vs. wallbox settings: Ensure there is no conflict between vehicle-side scheduling and wallbox scheduling.
  • Firmware update: Install the latest firmware, which may fix known scheduling issues.
