FAQs
Find answers to frequently asked questions about Synergi app.
What’s the point of using an app like yours?
Our app removes the manual timing of your electricity usage with the cheapest hours of the day. Our app automates it all for you without needing additional equipment to control your electricity costs. In the future, we will even reward you for being flexible and letting us adjust your electricity usage when there's a peak in electricity demand in your location, naturally, without affecting your lifestyle and comfort at home.
How do I actually save and earn money?
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 vehicle. This helps you save on transmission fees.
Later, we will allow you to earn rewards by letting us adjust your electricity usage further when there's a peak in electricity demand in your location, naturally, without affecting your lifestyle and comfort at home.
Can anyone use Synergi?
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, a variable tariff / spot-price electricity contract is recommended. However, even those with fixed-price contracts and an electric vehicle in the future can earn rewards by adjusting their charging during rush hours of the day.
Does it matter what electricity contract and provider I use?
With Synergi, you can save on your electricity bills, regardless of your electricity 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 more information about how to earn rewards later.
Is the app free and safe to use?
We believe that to better support the energy transition and flexible electricity consumption, we need to enable everyone to use electricity smartly.
So, the Synergi app and all its smart features—like Smart Charging, Solar Charging, and Smart Climate—are free to use for everyone.
At Synergi, your data privacy and safety are a top priority. We never save or store device login information (username, password) on Synergi systems. We only partner with reliable and widely recognized device connecting providers to connect to your devices via cloud services.
