About this app

Synergi is a free mobile app that connects to your home devices through the cloud, helping you use electricity when it's cheapest and best for the grid. No extra devices needed! The app features EV smart charging, smart heating & cooling, and EV solar charging.

EV SMART CHARGING
Smart charging feature finds the cheapest times to charge your EV—automatically.

Stay plugged in, set when you need your car ready, and we’ll handle the rest. With smart charging, you can save up to 50% on your annual EV charging costs. Functionalities in app:

SMART HEATING & COOLING
Connect your heat pumps and smart thermostats to Synergi, and let us automatically adjust your indoor temperature based on real-time energy prices—without ever switching off your devices. By shielding you from price peaks and making slight temperature adjustments, you can save up to 20% on annual electric heating costs, effortlessly. Functionalities in app:

EV SOLAR CHARGING
Solar charging is the smartest way to maximize your own solar energy production. EV charging starts automatically when your inverter begins generating power—you just set the charging limit (kW) in the app. No extra installations needed. With solar charging, you can save around €150 per year in transmission fees!
