Aiset is the Belgian leader in building energy data monitoring and analysis. BRAFT developed a smart mobile application for them that brings all of Aiset’s functionalities directly to a smartphone, fully offline. This solution allows building maintenance controllers to enter and manage large volumes of data without any network connection. Meter readings are performed using OCR technology. Developing this app was a major technical challenge, as it required handling complex backend logic and vast amounts of data entirely on a mobile device, ensuring smooth performance and reliability even offline.
