Everything the app knows, explained

Getting started

Unit setupAdd a unit from the setup card on the dashboard: pick the brand, then let the app scan your network or type the address yourself.Ventilation profilesThe unit runs one of several profiles — Home, Away, Boost and, where the machine has it, Fireplace — each with its own stored fan speed and supply target.Connection issuesIf the app can't reach your unit, check that your phone is on the same Wi-Fi network as the unit and that the address in Settings still matches the unit's address on your router.

Devices & home

Other ventilation brands (beta)Settings → Other units adds Enervent, Komfovent, Pluggit, Systemair and Helios over the local network (Modbus TCP), Vents and Blauberg over their own protocol, plus extra Vallox units.Power meters & smart plugsSettings → Power meters adds Shelly, Tasmota, TP-Link Kasa/Tapo, ESPHome or FRITZ!DECT purely for measurement.Air sensorsMost ventilation units measure a supply temperature and nothing else — no humidity, and CO₂ almost never.Personalize devicesOn the Devices tab each brand groups under its own logo — Shelly first, then power meters and ventilation units.Home profileRules tab → Home profile describes your house: area, floors, occupants and their daytime-away window, rooms with supply/extract terminals and duct sizes.Filter maintenanceReplace the supply and extract air filters roughly every 3-6 months, more often in dusty environments.Recording a filter change on the unit“Record a filter change” writes the date into the recuperator itself, so the **unit's own** countdown starts again — this is not the app keeping a private note.Planning filters in FiltaurioVentaurio knows what the hardware reports: the model, the unit's own last-change date and its countdown.Free cooling from outside airThe exchanger recovers heat, which is exactly wrong on a warm summer night — so the unit routes supply air around it instead of through it.When the exchanger has to thawIn hard frost the extract side of the exchanger ices up, and the unit pauses recovery until it has melted — the dashboard shows Defrosting while that happens.Remote access on a Vents unitVents and Blauberg units can be reached through the manufacturer's server, which is what lets the app work away from home.Local network or cloud firstOne switch, in Settings, for every device the app talks to: which route it tries first.

Measurements & diagnostics

Why efficiency sometimes shows no numberRecovery efficiency is the share of the indoor-to-outdoor temperature difference the exchanger gives back: **(supply − outdoor) ÷ (extract − outdoor)**.Both sides of the exchangerThe supply-side figure says how much heat the incoming air picked up; the exhaust-side one says how much the outgoing air gave away.Fan load: watts against the curveA fan's power rises with the cube of its speed, on top of a fixed draw for the electronics.Humidity and CO₂ controlEach profile decides for itself whether it answers rising humidity or CO₂ by raising the fans.Temperature control methodWhich air the unit steers by while it holds the supply target: the air going into the rooms, the air coming out of them — closer to room temperature — or cooling.

Smart features

AI advisorThe advisor analyses your recovery, energy and air-quality trends right on your device — nothing is uploaded to a server.AI filter monitoringAs a filter clogs, the fan must spin faster to move the same air.Week program & AIThe unit's own week clock runs profiles by the hour even when the app is closed.Week programme on a Vents unitThe unit runs its own weekly schedule, and it keeps exactly four intervals a day — each with a fan speed and a target temperature.The unit's timerA timed burst at a chosen speed and temperature, started from the Timer tile in the Unit section and counted down there second by second.AutomationsThe Smart Rules tab gathers every automation: geofencing (Away when you leave, Home when you return), night eco, auto-boost on CO₂/humidity spikes, weather scenarios and the unit's own week program.When to open a windowThe advice compares **absolute** humidity — grams of water per cubic metre — rather than temperature or the relative-humidity reading.What holds an automation backAuto-boost (Smart Rules → Auto-Boost) never acts on a single sample.Weather & smart climateWith a home location saved, the app pulls local weather and a 5-day forecast (free, no account).What CO₂ and humidity sayCO₂ tracks how many people are breathing in a closed room, and it is the number that says whether the ventilation is keeping up.Away without pressing itWith geofencing on, leaving the area around your home switches the unit to Away, and coming back returns it to the profile it had.Savings & trendsThe Statistics tab totals the money your recuperator saves by reclaiming heat, minus the electricity it uses, over today, 7 days, 30 days, a year and all time.

Widgets & Apple Watch

Home & lock-screen widgetsAdd the Ventaurio widget from the home screen or lock screen, then open Settings → Widgets to configure it: pick what each ring shows (fan, air quality, efficiency, CO₂, humidity or filter life), the four stat chips on the medium widget, and the two temperatures on the small one.Apple Watch appThe watch app mirrors your unit: swipe through status, control (profile, fan speed, boost timer), metrics, 24-hour air and temperature charts, savings and the daily AI tip.Daily summarySet a morning and an evening time in Settings and the app sends itself a short summary at each: what the exchanger recovered, what the fans drew and what that came to in money, for every unit in the home in one notification.Watch-face complicationsLong-press your watch face → Edit → add an Ventaurio complication.Alerts & notificationsTurn on Alerts in Settings to be notified about filter changes due, high CO₂ or humidity, faults and the unit going offline — even while the app is closed.

Data & privacy

What Pro unlocksPro unlocks the AI advisor and filter monitoring, advanced statistics with cost and tariffs, the monthly report, smart rules (geofencing, night eco, auto-boost, weather scenarios), the week program with AI optimization, cloud access and Google Drive backup.Face ID protectionExpert settings, week-program editing and its settings sit behind Face ID / Touch ID or your passcode — on by default where the device supports it.Backup & transferSettings → Backup saves your setup (unit & Shelly, smart rules and thresholds, statistics, preferences) to a hidden app folder on your Google Drive, or exports a .vhbak file to share.
