Home-Energy Autopilot Module

Alva Link optimizes your energy usage, production, and storage through your power systems, such as heat pumps, solar systems, EVs and home batteries. Anyone can install it themselves and with automatic operation, it lowers your energy costs in the background without you lifting a finger, saving you up to ~30% on energy costs.‍

_{Typical Central European homes save €700–€1,350 per year.}

Common questions

Where does Alva Link ship to?

All countries in Europe. Shipping outside Europe is not available at launch. Carrier, cost, and delivery time will be confirmed closer to dispatch. You’ll get all the details by email before your unit ships.

Can I cancel my pre-order and get a refund?

Yes. You can cancel any time before your device ships. Send a message via chat on alva.as or email. We refund your deposit in full. Processing typically takes 5 to 10 business days depending on your payment provider.

When will my Alva Link ship?

Shipping starts Q3 2026, prioritised by country and then pre-order sequence. Hardware design is locked, first prototypes are tested, and the enclosure is ready for tooling. You'll get email updates through production and a final confirmation before your unit ships. Remaining payment is processed only at that point.

Do I need one Alva Link per device, or does one Link control everything?

Each Alva Link connects to one energy asset.

Is Alva Link compatible with my heat pump?

Almost certainly, yes.

What's the difference between Alva Essential (free) and Autopilot?

Basic gives you manual control and safety features.

SMART HEATING

Your heat pump learns when electricity is cheapest

Alva Link reads your electricity prices (hourly or 15-minute intervals) and shifts your heat pump to the cheapest hours. Pre-heats when it's cheap, coasts when it's expensive. You set the comfort boundaries. Alva never overrides them.

✓

Adjust your heat-pump for optimal operating costs

✓

Always make sure your comfort level is met

✓

Learn your specific home with predictive heating

SOLAR OPTIMIZATION

Use more of the energy your panels produce

Excess solar? Alva redirects it. Charges your battery, pre-heats your home, or runs your heat pump. With the Netherlands phasing out net metering and Denmark reducing feed-in rates, self-consumption matters more than ever.

✓

Real-time production monitoring via your inverter

✓

Automatic load-shifting to use your own energy first

✓

Solar forecast for next-day planning

✓

Feed-in vs. self-use decisions in real time

BATTERY CONTROL

Advanced battery scheduling with Autopilot

Alva Link charges your battery when electricity is cheapest (or from solar excess) and discharges during peaks. Alva can also choose to use your battery at other times, for example for load balancing or when other situations demand it. When considering a charge, it always considers the health of your battery and the cost of running a battery cycle.

✓

Charge/discharge scheduling based on price curves

✓

Solar-first charging when panels are producing

✓

Protects battery health

✓

Configurable reserve (e.g. always keep 20%)

EV CHARGING

Charge your car when electricity is cheapest

Charges your car when electricity is cheapest: overnight at low spot prices, or during the day from solar surplus. You just plug in. Alva handles the rest.

✓

Solar-surplus charging during the day

✓

Overnight charging at the cheapest hours

✓

Load balancing to stay within your grid capacity

✓

Works with Zappi, Easee, Zaptec, Alfen, and any OCPP charger

BUILT TO LAST

Executes locally. Keeps running if your internet drops

Autopilot builds your schedule in the cloud using prices, weather, and your preferences. Sends it to your Alva Link. The device executes it locally over wired connections. Internet drops? It keeps running the last schedule. Your heating doesn't stop because your ISP has an outage.

✓

Device control runs locally over Modbus, OpenTherm, OCPP +

✓

Keeps executing the last schedule through internet outages

✓

Re-syncs automatically when connectivity returns

ALVA APP

Everything in one place. Not four separate apps.

Heat pump in one app. Solar in another. Battery in a third. None of them in coordination. Alva puts it all in one dashboard: real-time energy optimisation, savings, and what's happening next.

✓

Energy Autopilot for Solar, Battery, Heat-pump, and EV at once

✓

Predictive learning based on your preferences

✓

Upcoming schedule: what Alva plans to do and why

✓

Push notifications for unusual events or optimization wins
