How Optimaatti learns how your home heats and cools

Optimaatti automatically learns how your home heats up and cools down. You do not need to do anything — learning happens in the background. You can enable heating control right away, and the plan improves over days and weeks.

How does automatic learning work?

Optimaatti watches temperature, outdoor weather and heating behaviour. When enough measurements have accumulated, it learns how the room reacts to heating.

Fully automatic: the system periodically checks whether there are enough measurements for learning.
Smart scheduling: if normal use does not produce enough clear data, the system can plan a short learning test during a quiet period, such as at night.
Predictive heating works from day one: the estimate does not need to be perfect from the start. Control always keeps the temperature within your limits — only savings timing is not yet at its best initially.
Continuous improvement: the estimate improves over time as more measurements accumulate.

Can I speed up learning manually?

In most cases you don’t need to — automatic learning handles everything.
You can start a manual learning test if you want to speed up learning for a new device.
Manual testing is useful after changing sensor placement, heating power, or zone structure.
If the long forecast is much less accurate than the short forecast, a manual test can improve things faster.
For floor heating and heavy structures, shorter manual cycles can help make the estimate more accurate.

What happens before Optimaatti knows your home well?

This is a common concern, but there is no need to worry. Optimaatti is designed to work safely even when there are only a few measurements.

Control works immediately: the system uses safe default parameters that always keep the temperature within your min/max limits.
The only trade-off: savings timing is not at its best during the first few days. In practice the difference is small.
Regular plan updates: Predictive heating updates the plan every few hours using the latest weather forecast, electricity price and fresh measurements.
No risk: even if the estimate is initially inaccurate, temperature limits keep your home in the safe range.
The estimate improves on its own: typically 3–7 days of normal usage is enough for the first reliable estimate.

Manual learning test step by step

If you want to speed up learning manually, the learning test is in predictive heating settings under Forecast reliability. During the test the device cycles ON/OFF to produce a clear temperature response.

Open predictive heating settings Select the device and go to Forecast reliability.
Start learning test Click "Run learning test". The system starts controlled ON/OFF cycling.
Monitor Make sure the temperature evolves sensibly and does not exceed your limits.
Stop if needed You can stop the test at any time.

What happens after the learning test?

Everything happens automatically. Once the test completes, Optimaatti checks whether the forecast improved and enables predictive heating if the estimate is reliable enough.

Automatic learning Optimaatti uses the test measurements on its own — you do not need to do anything.
Reliability check If the estimate is not reliable enough yet, the system can plan a new learning test with improved settings.
Predictive heating activation When the forecast is reliable enough, predictive heating can be activated automatically.

Safety and design principles

Automatic learning tests are designed to be safe: they always respect your comfort schedule temperature limits.
The system automatically chooses a quiet time (e.g. night) when small temperature swings are least noticeable.
When predictive heating is already active, the system can learn softly: it steers temperature across a slightly wider range without a separate ON/OFF test.
Best data comes with minimal disturbances (doors, sun, sauna, fireplace, large internal loads).
You can check learning status under Forecast reliability at any time.

Frequently asked questions

Do I need to do anything before predictive heating starts working?

No. Just set your temperature limits (min/max) and enable control. The system learns the rest automatically. Control works safely from day one.

Why doesn’t electricity price affect control right away?

Because savings timing requires knowledge of how fast your home heats up and cools down. During the first few days, control focuses on keeping the temperature within your comfort zone. The estimate typically improves in 3–7 days.

How do I know when the forecast is reliable enough?

Forecast reliability shows the confidence score and prediction accuracy. The system also notifies you when the forecast is ready for full predictive control.

What about old houses with high thermal mass?

Optimaatti sees slow-heating and slow-cooling homes from measurements. For heavy structures, learning may take a bit longer (1–2 weeks), but control works safely throughout.
