This app is for users who wants to manage their meeting room availability by adding an iPad in front of the meeting rooms. As soon as someone enters the meeting room, he can select the duration of the meeting. Others will see in red color that this meeting room is unavailable until time X. Additionally, the user can add a netatmo device to manage Co2 levels in the meeting room. The Co2 level will show in the meeting app with a green, yellow or red cloud for each meeting room. This will help the user to push fresh air into the meeting room.
