How to Fix / Troubleshooting

Safety: No special hazard; changes are software-based.

  • Sync time: Open the Mammotion app and synchronize the mower's time and date with your smartphone.
  • Check time zone: Ensure the correct time zone and daylight saving settings are selected.
  • Firmware update: Install any available firmware updates that address scheduling or clock issues.
  • If time drifts significantly even after sync, the mainboard RTC circuit may be faulty and require replacement.
