How it works.

With Liase, you can easily track your ventilation habits using an old, unused smartphone. Press the button when you start or finish ventilating. Notifications help you remember to close the window in time or remind you when it is time to ventilate again.

Look
At its core, the app consists of a single button that can be linked to any notification rules.

More than just an app.
Unlike a conventional app, the smartphone is placed in the home after setup and remains active at all times. This makes it accessible whenever needed and easy to use, even for less tech-savvy users.
Set it up. Place it. Use it.

Who is it for?

Regular ventilation helps reduce moisture and stale air indoors. However, it is easy to forget to ventilate in everyday life, or to leave the window open longer than planned.

Liase helps you keep track of your ventilation habits and reminds you at the right time.

How it works

Set up an old smartphone using our assistant and place it where you regularly ventilate. When you start ventilating, simply press the button. Once you close the windows, press the button again to end the session.

All sessions are saved and can be viewed in our web portal and exported for further analysis.

Notifications help you

If you have not ventilated for a certain amount of time, Liase will remind you. You can set the interval yourself, as well as define quiet periods when you do not want to receive notifications, such as at night. Liase can also notify you if a ventilation session lasts unusually long. This reminds you to close the windows before a short airing session turns into unnecessarily prolonged ventilation.
