Fybra is the smart sensor that monitors the air quality in your office or room and tells you when and for how long to open the window. Download the app and start monitoring your indoor air quality data: follow the light of the device (red light: open! blue light: close!). The algorithm will learn your own habit and will guarantee the best air you can get in your office or room. If the system is connected with the mechanical ventilation everything will be automatic and you will see everything from the monitoring here! From the app you will set up the timer and decide if the light will be turned off or on.
