EV Charger

An EV charger (technically an EVSE, since the charger itself lives in the car) is usually the single largest controllable load in a home. Connected to Home Assistant over a local API, Modbus, or OCPP, it exposes charging state, session energy, and per-phase power, and accepts commands to start, stop, and cap the charging current in real time.

How Selora AI uses EV chargers

• Solar-surplus charging that continuously adjusts amperage so the car soaks up excess production instead of exporting it.
• Tariff-aware schedules that shift sessions to off-peak windows and pause them during demand peaks.
• Load management that throttles the charger when the range, dryer, or heat pump kicks in, keeping the panel under its service limit.
• Session tracking with per-charge energy and cost, so clients can see exactly what each fill-up costs.

Why local control matters

Cloud-tethered chargers stop responding when the vendor’s servers or the home’s internet go down, and some makers have moved basic features behind subscriptions. A locally controlled EVSE keeps automations working, keeps session data private, and never sends an installer a support ticket because an API was deprecated overnight.
