Your heat-recovery ventilation, finally with a great app.
Ventaurio talks to your unit over your own network — no vendor cloud required — and shows what it never told you: how much heat it actually recovers, what that is worth in euros, when the air goes stale, and when the filters genuinely need changing.
What it actually does
Not another remote control with a fan slider.
Real money, not percentages
The recovered heat valued against your electricity price, with day and night tariffs. You see what the machine earned today.
Live dashboard
Temperatures, CO₂, humidity, fan speed and power draw — read straight from the unit, updated continuously.
Smart scenarios
Night cooling, heat shield, frost guard and geofencing. The unit reacts to weather and to whether anyone is home.
Weekly programme with an AI optimizer
Suggests a schedule from the forecast, your CO₂ history and the household's rhythm. You approve it — it never changes things behind your back.
Power metering
Pair a Shelly, Tasmota, TP-Link, ESPHome or FRITZ! plug and the savings maths stops being an estimate.
Widgets, Siri, Apple Watch
Home-screen widgets, voice shortcuts, and a native watch app with complications. Boost without unlocking the phone.
Works with your unit
Over the local network. Vendor clouds are supported but never required.
Local-first, and we mean it
No servers of ours
Your ventilation data is read on your network and stored on your phone. There is no Ventaurio backend to leak.
AI on your own key
The AI features use an API key you provide. Requests go from your phone straight to your provider — we are not in the middle.
No ads, no data sales
The app is paid for by the people who use it. That is the entire business model.
Pricing
Free is a usable app, not a demo.

Questions people actually ask
Do I need an internet connection?
No. The app talks to your unit over your home network. A cloud account is optional and only useful if you want history while the app is closed, or control from outside the house.
My unit is not on the list. Will it work?
Probably not yet, and we would rather say so than sell you a maybe. Write to us with the model — most units speak Modbus TCP, and adding an adapter is a fortnight of work when there is someone to test it with.
What does the AI actually do?
It reads your ventilation statistics and suggests a weekly schedule and threshold changes. It never applies anything on its own — you see the proposal and approve it. It runs on an API key you supply, so it costs us nothing and we never see the requests.
Are you affiliated with Vallox or the other manufacturers?
No. Ventaurio is independent. Brand names appear only to identify which devices the app is compatible with.
What happens to my data if I stop paying?
It stays on your phone, because that is where it always was. Pro features stop; nothing is deleted and nothing is held hostage.
