Here you can find the latest changes in Optimaatti: new features, improvements and bug fixes.
EV charging reliability and fault handling
Your charge point now reports the reason for a fault (for example a ground failure or over-current) — not just "faulted". You know what is wrong and when to contact service.
You get a notification if your charge point goes offline or into a fault state.
Optimaatti recovers automatically from charging interruptions: an interrupted session is closed cleanly, the station status is re-synced when the connection returns, and charging is not started against a faulted station.
Your car battery level is shown in the charging view when your car and charger share it. The former "Charging level" is now "Charging power" for clarity.
EV charging billing for individuals
You can now bill charging on your own pricing basis (spot price or fixed price) and get an itemized breakdown of every charging session plus a total — on both web and mobile.
Your electricity contract type (spot or fixed) can now be selected in settings, so savings and cost figures are calculated correctly for your contract.
All charging rules — price, solar, schedule and load management — are now editable directly in the mobile app.
Clearer heating results and EV charging guidance
Winter heating results are only published after enough measurement data has been collected. The results page clearly explains what was measured and what ordinary heating is used for comparison.
You can now select the measurement period when reviewing a reference result. This keeps the comparison limited to days with sufficiently complete heating-consumption data.
EV charging now has a clearer starting point and charge point setup guide. The app also explains why charging is waiting, for example because of price, solar generation, or load management.
Load-management guidance now makes clear that it is an additional control layer. Electrical fuse and overload protection must always remain in use.
EV charging: OCPP 2.0.1 support and better setup instructions
OCPP 2.0.1 support: Optimaatti now supports both OCPP 1.6J and 2.0.1 charging stations. The protocol version is negotiated automatically when the station connects — no manual version selection needed.
Clear charge point setup guide right inside the app: Charge points → Setup guide. A step-by-step walkthrough from pairing details to the station's OCPP settings, with recommended values and troubleshooting.
The charge point list now shows the active OCPP version, and smart charging support is detected automatically.
Consumption and cost data: charging energy and cost are shown per transaction; 2.0.1 stations also receive a running cost and a summary message on the station display.
Better compatibility: the vehicle's departure time and energy need (ISO 15118 charging negotiation) can be fed straight into cheapest-time charging optimisation.
Device planner: home automation, save & PDF print
Home automation planning: the planner now covers lighting, sensors (motion, door/window, temperature, buttons) and scenes — not just heating loads.
Expanded Shelly catalog: 26 products. Plus 1PM/2PM and Mini family for lighting, Plus i4 for button circuits, Plus Plug S for outlet metering, BLU Motion / Door-Window / Button1 / H&T / TRV sensors, Wall Display 4" touch panel, Pro Dimmer 0/1-10V for dimming.
Save your plans: name them, add notes, come back later or share with an electrician. List view and one-click reopen back to the result view.
Print / Save as PDF: every saved plan can be printed as a clean A4 document — your browser's "Save as PDF" works directly.
Per-device metering by default: every controlled load gets its own measurement so savings are shown per device in euros. The validator now also auto-injects a BLU Gateway when sensors lack one.
Quick shortcut in the AppBar and on the Dashboard — the planner is one click away from any view.
Active Automations, mobile improvements and design system
Active Automations page: every rule that is currently running, on one screen, filterable by device and rule type. Easy to see what is actually controlling your device right now.
Mobile improvements: wider content areas (md breakpoint), DataTable folds into card view on small screens, the back button never gets clipped on tablets.
Design system: unified radius and typography scales, refreshed focus token for keyboard rings, buttons and transitions polished to feel softer.
Savings views aligned: KPI numbers match across tabs, breadcrumb back to the main savings page.
Fixes: charts no longer crash in the production bundle, the dashboard sidebar is always reachable, an expired session no longer triggers a redirect loop.
Profile levels (Easy / Managed / Expert) and a unified rule editor
Profile level is now a user choice: Easy (minimal view), Managed (full toolkit), Expert (all knobs). The app hides advanced features at lower levels so the UI stays clean.
Easy mode everywhere: bigger buttons, glossary popups ("what does predictive heating mean?"), a help button on every screen, two-step confirmation for destructive actions.
SmartPriceRule — one unified rule editor: a single view that replaces the older PriceRule + PriceRuleV2 forms. A banner walks old rules through the migration.
OneClickRuleCreator: ready-made cards for typical goals ("Save on heating", "Charge the car cheaply") created with one click.
Upgrade hints for beginners: when a user reaches a feature that needs a higher level, a single button raises the level and returns them instantly — no menu hunt.
New: Home Shelly device planner (beta)
AI-assisted planning: answer 3–5 questions about your home (housing type, large loads, free DIN slots in your panel) and get a ready-made Shelly Pro device proposal.
Always includes whole-house metering (Pro 3EM-50 or Pro EM-50) — so you see verified savings in euros, not just estimates.
For heating loads only Shelly Pro series is recommended, by rule: water heater, sauna, car heater and underfloor heating are switched safely through a contactor when needed.
Output: priced shopping list, installation order, and a clear split between "electrician tasks" and "DIY tasks".
Available in onboarding as a light 3-question starter pack, and in the beginner profile as the full wizard with ready-made house presets.

Added links on the predictive heating help page so the new guides are easy to find.
Added an electric car charger help page (beta): the charging station feature is in testing and may change based on feedback.
Optimization: more robust behavior with tight comfort limits
Predictive heating can automatically retry when comfort limits are too tight and a plan cannot otherwise be produced.
Optional temporary relaxation can be applied to comfort bounds so you still get a usable plan instead of an empty result.
Improved handling of small schedule gaps so planning does not fail on minor missing data.
Zigbee: smoother setup
Improved Zigbee setup docs and configuration flow to make gateway startup and configuration more straightforward.
Spot electricity prices added to the marketing site
Added spot price data to marketing site content and examples.

Updated sitemap to include the new help URLs.
Homepage copy clarified
Clarified the main message and reduced technical terminology on the homepage.
Improved hero typography and layout (readability, line length, spacing).
Clarified that the service currently works only with Shelly devices.
Added dark theme to the marketing site (theme toggle in the top navigation).
New guided rule setup, rooms and solar control
Added guided rule setup for price rules, schedule rules and temperature rules — easier onboarding without learning every field at once.
Improved AI assistants: clearer explanations and suggestions for price, temperature, schedule and predictive heating settings.
Finalized rooms, light groups and sensor flow: create room-based light groups and connect motion and ambient light sensors to groups.
Added solar control profiles for water heater: power limits (W), time windows and safety limits help use cheap hours and avoid main fuse overload.
Updated marketing site docs and features pages to reflect new functionality (guided rule setup, rooms & lighting, solar control).
Demo devices make it easier to try
Added the ability to create virtual Shelly demo devices to try Optimaatti without controlling real devices.
Demo devices use the same prices, rules and predictive heating calculations as real devices — you can add rules and track impact like in production.
Demo devices appear in the normal device list and can be reset with one button if you want a clean start.
New roles: Owner, Family member, Viewer
Added household roles: Owner (full control), Family member (daily control) and Viewer (read-only).
Editing devices, rules and schedules is now restricted by role — family members can use the system without accidentally breaking settings.
Detailed device views and stats remain visible for Viewer role, but control buttons are disabled.
Improved device connection details and security
New device connection details work immediately after creation without a manual password reset.
Device connection details are shown in one place, so setup no longer depends on the account sign-in password.
Marketing site content updates
Added a pricing page and clarified benefit-focused content.
Improved help section structure and linking (getting started, devices, FAQ).
AI assistants for rules and predictive heating
Added AI assistants for price rules, temperature rules, schedule rules and predictive heating settings (comfort zones and thermal model).
Device lists now filter sensors and show only controllable devices or relevant sensors depending on context.
