The practical answer
Many smart chargers can still charge even when Wi-Fi or the app is offline. Separate power delivery from app features first. Then check Wi-Fi signal, 2.4 GHz requirements, account state, firmware, utility-rate schedules, and charger reboot behavior.
Decision path
- Confirm whether the car charges when plugged in.
- Check the charger's indicator lights before chasing the app.
- Move Wi-Fi troubleshooting to the network layer if charging still works.
- Recheck schedules and current limits after reconnecting the app.
