Device planner expanded: home automation, save & PDF for the electrician

A few days ago we launched the AI-assisted Shelly device planner. We promised to keep iterating.

Here's what's new.

Home automation in scope — not just heating

The first version focused on heating loads: water heater, sauna, car heater, underfloor heating. Now the planner also understands:

• Lighting — add light circuits per room (living room, hallway, outdoor lights…). The planner suggests Plus 1PM, 2PM or Mini Gen3 for the right install location.
• Sensors — motion (BLU Motion), door/window (BLU Door/Window), buttons (BLU Button1), temperature/humidity (BLU H&T or Plus H&T), and radiator valve thermostat (BLU TRV).
• Scenes — describe what you want in plain words ("when the door opens and it's dark, turn on the entrance light for 2 minutes"). The plan confirms the required devices are present.

The very first wizard step now asks what you want to do — save on heating, home automation, plug-metering, or all of these — and only shows the questions that apply.

Plans are saved

Previously the result appeared once and disappeared with the page. Now:

• Save button on the result view. Give it a name (e.g. "Cottage in Hanko", "Käppyrinpolku house") and optional notes.
• Saved plans list at its own URL: updated date, housing type, device count and total cost at a glance.
• Click a plan to reopen it back in the result view — fork another version (a copy) or delete.

Critically: a saved plan stays as it was, even if the catalog changes underneath. Prices and recommended models are persisted exactly as you saw them.

Print or share as PDF for the electrician

Electricians want paper or a PDF — not a browser view. The result view now has a "Print / PDF" button that opens an A4-friendly layout:

• Header with date, "OPTIMAATTI · DEVICE PLAN"
• Household details: housing type, heating system, phases
• Shopping list as a table with prices and a total
• Contactors (for loads above 16 A)
• Panel layout by DIN slot
• Electrician's tasks and DIY tasks side-by-side — clear division of labour
• Disclaimer: "This is an AI-assisted suggestion, not a final electrical plan. The electrician verifies wiring and breaker sizing."

Your browser's "Save as PDF" works directly — no library, no download.

Per-device metering is now the default

Previously the whole-house meter was mandatory and per-device metering was a recommendation. Now per-device is the default: every controlled load gets its own measurement so savings are shown per device in euros (not just a household total).

In practice that means:

• Small 1-phase loads → Pro 1PM/2PM/4PM (built-in relay + meter)
• Bigger 1-phase loads → Pro EM-50 (two measurement channels + a dry contact for a contactor)
• 3-phase loads → Pro 3EM-63W Gen3 (direct screw connection, no CT clamps) or Pro 3EM-3CT63 (with CTs), paired with a Pro 3 relay for the contactor
• Whole-house metering remains possible and recommended, but isn't auto-injected if every large load is already metered per device

Quick shortcut from any view

Every page's top app bar has an Assignment icon that jumps straight to the planner. The Dashboard has a highlighted card on every profile: "Plan your home Shelly devices". One click is always enough — the planner doesn't hide several menu levels deep.

Where to start

Logged-in users: top-bar Assignment icon, or the new Dashboard card → planner opens.

New users: start a free trial → on the first device-choice screen pick "I don't own a Shelly yet — plan my purchases" → the planner walks you through.

Iteration continues — feedback welcome.
