Measured data from a real home — not a promise, an example.
One simple idea
Electricity prices change hour by hour. Optimaatti does just one thing — it moves your big loads to the cheap hours.
Estimate your savings
Pick two things about your home. We’ll show an estimate right away.
We pre-fill your choices — you’re set up in a minute.
An estimate, not a promise. Based on a typical electrically heated home. Actual savings depend on your devices.
Here’s what one home saved
We compared the same home two ways: Optimaatti’s control vs. an ordinary thermostat. This is measured data — no dressing it up.
This is one real home’s data, not every home’s promise. We show it transparently in euros, energy and emissions.
Three steps, about 10 minutes
You don’t need a new house or an electrician right away. Start with one device.
