lüft - SunRADON1.18 - App Store

Mobile app for lüft made by SunRADON, the company trusted every day by Radon and Indoor-Air-Quality professionals worldwide to monitor homes, schools, workplaces, and health care facilities.
Because clean air matters, the lüft mobile app provides you easy access to monitor your Indoor-Air-Quality from anywhere and anytime. A dashboard view gives you access to (6) IAQ sensor readings at once. Traffic light color coding of the sensor readings quickly visualizes elevated or even dangerous readings. The app also provides Indoor Mold Risk and Outdoor Air Quality Risk Indicators for a complete analysis of the air surrounding you.
Because Air-Quality and Radon levels fluctuate based on your home’s ventilation, airflow, and weather conditions the built-in trend charts let you drill down and review short- and long-term fluctuations from a single day to a year. Setup up custom alerts and notifications when thresholds are reached to take actions to improve the air you breathe.

The lüft Mobile app advanced features also allows you to program the integrated Nightlight function to suit the comfort of your home, synchronize temperature with other lüft(TM) or HVAC, securely share data with Indoor-Air-Quality professional of your choice, and setup to receive daily, weekly, or monthly air-quality summary reports. It further allows to download trend data for even more in-depth analysis when needed.

Setup as easy as 1-2-3: download app, plug in device, and follow the on-screen instructions.
