About this app
VentUI lets you monitor and control compatible ventilation units from your phone over your local Wi-Fi network.
Compatible device families include Bosch Vent 5000 C, Junkers Aerastar Comfort, Dantherm HCV and Buderus Logavent HRV2. Compatibility and features depend on the model, controller electronics, firmware, network interface and installed sensors.
On supported units you can:
• Switch between on-demand, manual, weekly and holiday modes.
• Adjust fan speed in manual mode.
• View supply and extract air temperatures.
• Check humidity, VOC, CO₂ and remote-control temperature when the relevant sensors are available.
• Check filter status and reset the filter timer.
• View fireplace, night, summer and bypass status.
• Adjust the clock, manage schedules and access device configuration tools.
TRY IT WITHOUT A VENTILATION UNIT
Choose “Try demo” on the first screen or in Settings. Explore sample readings and controls without an account or a connection to hardware. Changes in demo affect sample data only.
LOCAL NETWORK REQUIRED FOR REAL HARDWARE
Your phone and ventilation unit must be on the same local network, with a compatible Modbus TCP interface. Some installations require DHCP to be enabled through the manufacturer's USB configuration tool. Setup guidance is included in the app.
VentUI is free, with no account or subscription required. Small ads appear below fan speed controls and device discovery in Settings. A full-screen ad may appear after a successfully saved schedule. Optional Firebase usage statistics and crash reports are off by default and can be managed in Settings.
App interface languages: English, Polish, German and French.
