What is the best first device to start with?
If you do not want to build everything at once, start with one load where the benefit is easy to see.

Save money without constant tweaking
Optimaatti helps you save with spot pricing, flexible electricity contracts and also many fixed-price everyday use cases. The impact is visible in euros, energy and CO₂ directly in the app.

Flexible electricity control released
Lower electricity bills without watching prices all day
Automatic control you can override any time
See the monthly CO₂ impact too
Below is a real example of how the system affects money, energy timing and CO₂ during a month.
Current month
Why does this matter?
Savings should not be vague. That is why we show the impact in euros, shifted energy and reduced CO₂.
The comparison uses thermostat control as the baseline, representing a more traditional way to run the same home without smart optimization.
This is not a promise of identical results for every home — it is a transparent example of how impact can be made visible.

Three strong reasons to get started
These are the best entry topics for new users right now: an easy start, clear savings and visible everyday value.
How much can water heater control save?
A water heater is often the best first target because the benefit shows up quickly without making daily life harder.
Read the water heater savings exampleHow do you avoid unnecessary peak loads at home?
Savings do not come only from cheap hours. Smoother usage and fewer unnecessary peaks help too.

Useful with different contract types
Optimaatti is not only for spot pricing. Savings come from different things depending on your contract and daily energy use.
Spot pricing
Savings come from shifting consumption automatically to the cheapest hours.
- Use the cheapest hours without manual checking
- Especially useful for heating, water heaters and EV charging
Flexible contracts
Savings come from reducing the consumption effect and moving usage to better periods.
- Shift loads away from expensive and high-impact moments
- See when control actually improves the contract outcome
Fixed-price contracts
Value comes from smarter routines, automation and better control of consumption peaks.
- Avoid unnecessary simultaneous loads and overheating
- Keep daily life easier and energy use visible even without spot pricing
Same system, different source of savings: cheaper hours, lower consumption effect, or smarter daily usage.

Process
How does it work?
Four simple steps to start saving. Setup takes only a few minutes.
1. Connect your devices
Add your Shelly devices using connection details (MQTT). Automatic discovery makes it easy.
2. Create rules
Choose when devices may run. Start with guided rules or use the full editor for finer control.
3. Or just enable predictive control (MPC)
If you want, MPC plans usage automatically from price and weather while staying within your comfort limits.
4. Save money
Track savings in real time. Typically 20–30% lower electricity bill.
