Our app removes the hassle out of timing your energy usage. It automatically shifts your consumption to the cheapest hours of the day to save you money. No extra equipment or installations are required: Synergi connects directly to the cloud service of your devices. If you are in Finland, Synergi app is only available via a partner energy provider. Check the list here.
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 heating & cooling.
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.
With smart charging and smart heating & cooling, we shift your consumption to hours when electricity prices are lower. Savings will accumulate according to your usage frequency.
Outside Finland, anyone with a supported device (electric vehicle, solar panels, or heating and cooling devices) can use the app. See all supported models here.
In Finland, Synergi is available to customers of our partner energy providers, Helen and PKS. If your provider isn't a partner, you can switch to a partner electricity contract.
For optimal savings, a variable/spot-price contract is recommended.
We partner with energy providers, who offer Synergi to their customers. That's what funds the app, so it comes at no cost to their customers. In Finland, this is why the app is only available through our partner energy providers.
