Most EV chargers are smart enabled, so you will need to ensure you can detect and connect to your Wi-Fi network at the installation point; you can test this beforehand through your mobile phone. If you cannot connect to your Wi-Fi network you should consider a Wi-Fi booster or an alternative installation location. Once installed, you will then control your smart EV charger through its associated partner app to use the cheapest and greenest electricity available (depending on your energy tariff).
