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.
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 threshold (kW) in the app. No extra installations needed. With solar charging, you can save around €150 per year in transmission fees!
