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!

FAQs
Find answers to frequently asked questions about Synergi app.
Our app removes the manual timing of your energy usage to the cheapest hours of the day. Our app automates it all for you without needing additional equipment to control your energy costs.
In the future, we will also reward you for being flexible and letting us adjust your energy usage when there's a peak in electricity demand in your location, naturally, without affecting your lifestyle and comfort at home.
You can save money with us in several ways. To get started, you must have a supported device and model to use at least one of our smart features: smart charging, solar charging, or smart climate.
With smart charging and smart climate, we shift your consumption to hours when electricity prices are lower. The savings will be tailored to your usage frequency and your home's conditions.
With solar charging, we allow you to use some of your self-produced solar power to charge your electric car. This helps you save on transmission fees. Later, we will allow you to earn rewards by letting us adjust your energy use further when there's a peak in electricity demand in your location, naturally, without affecting your lifestyle and comfort at home.
Anyone can download the app. However, to benefit from it, you must have a supported device (electric vehicle, solar panels, or heating and cooling devices) and model. You can see all supported models from this link. Furthermore, the app's features like smart charging and smart climate are designed to give you control. For optimal use, variable/spot-price  is recommended. However, even those with fixed-price contracts and an electric vehicle in the future can earn rewards by adjusting their charging during busy hours of the day.
With Synergi, you can save on your electricity bills, regardless of your energy provider. However, a spot-price contract is essential for making the most of the cheapest hours of the day and using our smart optimization features.
But even if you have a fixed-price contract, there's potential for rewards in the future. We will share  information about how to earn rewards later.
Why is Synergi free? There's no catch—we're committed to keeping it that way. We build partnerships with utilities and other energy companies so the app comes at no cost to you!
For example, Synergi operates as a virtual power plant and participates in grid balancing. In return, national grid players reward Synergi and its users.
At Synergi, your privacy and security are our top priority. We never store or save your login details (such as usernames or passwords) on our systems. We partner only with trusted, well-known providers to securely connect your devices via cloud services.
