Smart (networked) charger
A smart charger connects to Wi-Fi (or Ethernet/cellular) and adds app control: scheduling for off-peak rates, energy tracking, load management, and participation in utility demand-response programs.
Many utilities pay rebates of $50–$500 specifically for networked chargers enrolled in their smart-charging programs — often enough to cover the price difference over a "dumb" charger.
The trade-offs are dependence on the manufacturer’s app/cloud staying alive and occasional connectivity glitches. Non-networked chargers have nothing to break; scheduling can instead be done from the car’s own app.
