Information and communication technologies have a role to play in improving a citizen's quality of life. The ageing world population demonstrates the major challenge of assisting citizens in their various activities. ICTs could help them to have a healthier lifestyle, reduce physical efforts, reduce the risk of disease and prevent accidents or illnesses. PEACE aims to provide a system allowing the association of any type of sensors or data sources with any action within the user's environment. The generic approach of this system allows it to be deployed in several backgrounds. Indeed, multiple purposes can concern home automation, clinical environment automation and progress in the Ambient Assisted Living field. Creating this system required focusing on multiple areas like user interaction paradigms, I/O management, security management systems and automatic services discovery. Developing this project has demonstrated significant future job possibilities. Indeed, the implemented use-case is applicable to clinical environments and to domestic environments. Furthermore, this opens the door to enable the realisation of automation in the citizen's environment.
