Possible Causes

Incorrect time zone or clock setting, Overlapping or conflicting schedules, Vehicle-side schedule overriding charger schedule, App not synchronized with charger

How to Fix / Troubleshooting

Safety first: No high-voltage work is needed for scheduling issues.

Steps to try:

  • Check time settings: In the app or charger menu, verify the current time, date, and time zone are correct.
  • Disable vehicle schedule: Temporarily turn off any charging schedules set in the vehicle so only the charger schedule is active.
  • Simplify schedule: Set a single daily schedule window and test if charging starts as expected.
  • Sync app: Log out and back into the app, or refresh the charger connection.

When to call a technician: If scheduling still fails after configuration checks, the internal clock or firmware may need service or update.
