What users are saying:

Thanks to the rewards program, I get spot-price electricity management for free – and on top of that, I earn rewards. It’s a pleasant surprise to see the points accumulate. But the best part is that I can leave my car plugged in and trust that it will charge during the cheapest hours.

Jouni

Surprisingly easy to use when you learn the functionalities. It clearly shows how the heat pump will adjust the temperatures. Now I’m only annoyed about the fact that I didn’t start using the service earlier!

Heikki

Great service and easy user interface! We have some controls on electricity but this is much more consumer friendly. Keep pushing forward, this country is full of people who need this!

Sanna

I’ve been using Synergi for some weeks, and I’m liking it more and more! I also linked our solar panels, so I can charge my EV according to the output of the panels. One difference compared to other apps is that when you take the control off Synergi, it just doesn’t turn on by itself.

Jussi

I can see my EV charging stats in one place, which helps me to report them to my condominium. No need to fight with my neighbors as I know how much I have charged and at what cost. Also, automatic scheduling is a major bonus.

Juha

Synergi made it easy to save over €100 on car charging by automatically finding me the cheapest hours to charge my cars.

Why should I use Synergi?

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.

How do I save 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 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.

Can anyone use Synergi?

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.

Why is Synergi free?

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.
