Disclaimer: Our app and ecosystem are not compatible with JuiceBox chargers. Voltie and Voltie.eu are independent entities and are not affiliated with VoltiE in the US. The Voltie app is the control centre for smart charging with Voltie electric car chargers. Start, stop and schedule charging from anywhere, track your consumption, and get the most out of your solar system — all from a single, easy-to-use interface. Voltie chargers are developed and manufactured in Hungary, and their Type 2 connector works with every electric vehicle. With the app you can: • Charge from anywhere – Start or stop charging from your phone, whether you're at home or on the road. • Smart charging modes – Automatic (Plug & Charge), scheduled, energy-based (kWh) and time-based charging, plus a battery-friendly mode. • Solar charging – With Green mode you charge purely from your solar surplus; in Eco mode the grid tops up the rest. • Grid Control – A feature unique on the market: even at high grid voltage your solar inverter keeps running, so your daily production isn't lost. • Dynamic load management – The charger always uses your home's available capacity, so it never overloads your main fuse. • Smart home integration – Voltie is an open system (OCPP, HTTP API, Modbus), so it fits into your smart home, including Home Assistant. • Detailed statistics – Track charged energy, time, distance covered, CO₂ savings and cost by day, week, month and year; you can also receive your data in Excel by email. • RFID and multi-user management – Start charging with an RFID key and control access at home, in the office or at your accommodation. • Always up to date – Voltie receives regular updates, so your charger stays current for years.
