Offline Behavior

How the EV Charger handles offline scenarios: charging, scheduling, and data logging

Updated over 2 weeks ago

Does the EV Charger Require WiFi?

No, the charger functions at default settings (40A for NEMA 14-50, 48A for hardwired) without WiFi. However, adjusting charge rates or enabling automated features requires an initial setup via the Emporia app.

Data Logging During Outages

  • Short outages (<20 min): Data is stored and uploaded once the connection is restored

  • Long outages (>20 min): The charger tracks cumulative energy usage and averages the data into records once reconnected. While total energy consumption remain accurate, individual time-based records may be estimated. In rare cases, the charger may lose track of cumulative usage, potentially resulting in data loss

Charging and Controls While Offline

  • The app cannot control the charger without WiFi

  • If the charger was "Ready" before losing connection, it will continue charging

  • If "Paused", it must reconnect to resume charging

  • Manual Override: Plugging in the charger twice while offline turns it on until a scheduled off event or manual shutoff occurs

Scheduled Charging While Offline

Pre-set schedules remain active, but updates require an internet connection
