Plan your home Shelly setup with AI assistance

We have shipped a new feature that takes the hardest step on the smart-home journey off your shoulders: which Shelly devices to buy and where to install them.

Answer a few questions about your home and you get a ready proposal.

Why we built this

Most people get stuck on the same questions:

• Should I buy a Plus 1PM or a Pro 1PM?
• How many channels do I actually need?
• Where in the panel does each device go, and is there room?
• How do I prove I am actually saving money?

We tried to answer these with guides and tables. That is not enough, because the answer depends on your home — its loads, your panel layout and your goals.

The new planner does that work for you.

How it works

1. Housing type. House, semi-detached, terraced, or apartment. This determines whether you have access to your own electrical panel.
2. Large loads. Water heater, sauna, car heater, ventilation, underfloor heating, heat pump. Pick the ones you want to control and estimate their kW (we help).
3. Free DIN slots. How much room in the panel — or pick "I don't know" and upload a photo for an estimate.
4. Goal. Savings %, comfort, or peak load shaving.
5. Get a proposal. A priced shopping list, a recommended install order in the panel, and a clear split between "electrician tasks" and "DIY tasks".

What every proposal always contains

Whole-house metering. We always include either Shelly Pro EM-50 (single-phase) or Pro 3EM-50 / Pro 3EM-3CT63 (three-phase) with current transformers. This is non-negotiable, because without baseline metering, savings are guesses — and guesses don't convince anyone.

Per-load control with metering. For controlled heating loads we propose Pro 1PM, Pro 2PM or Pro 4PM depending on how many circuits you control. Each channel measures its own consumption — so you see directly how much the water heater or the sauna saves.

Contactor when needed. If a load exceeds 16 A (e.g. a 3×16 A water heater or sauna heater), the proposal includes a contactor. The Pro relay drives the contactor, the contactor drives the load.

The rule on heating loads

One rule is hard and we don't bend it: for heating loads (water heater, sauna, car heater, underfloor heating, ventilation) we always propose Shelly Pro series — never Plus or Mini.

Two reasons:

• Safety. Pro devices have better ratings, better protection and are designed for DIN-rail panel installation, where heating-load control belongs.
• Continuity of measurement. Pro PM devices stay in the catalog longer than smaller consumer models, and firmware support is longer. Measurement data is needed for years, not months.

This rule is hard-coded into the planner, so you cannot accidentally end up with a Plus device recommended for sauna control.

Can the AI be trusted?

Not blindly. The planner uses AI to phrase the proposal and to optimize channel allocation, but:

• The device list comes from our database, not from the AI's head. The AI cannot invent a device that does not exist.
• The server validates the response before showing it: every proposed product exists in the catalog, every heating load has metering coverage, and the DIN slot count fits.
• The result is always a recommendation, not a final installation plan. The "electrician tasks" list is clearly marked.

Where to find it

• Onboarding (new users): a light 3-question version. You get a starter pack proposal, and you can come back for the full plan later.
• Beginner profile: the full wizard behind a "Plan my home" card. Comes with ready-made house presets (e.g. "Electrically heated 130 m² detached house, family of 4") so you can start with one click.

In beta we are looking especially for feedback on how realistic the proposals feel — does an electrician's quote land in the same range, and does the proposal really fit in your panel?

Where to start

If you are already an Optimaatti user, you'll find the new planner on the beginner profile home screen. If you are still considering smart home automation, start a free trial — onboarding leads straight to the planner.

The planner is in beta: prices and the device list will keep updating, and new models are added. Tell us if a proposal feels off — we learn from it.
