We present our team IHSEV, and our preliminary studies to tackle the question of interoperability of devices and robots for smart homes. We propose a framework enabling the seamless communication between smart home devices and robots. Our framework relies primarily on the xAAL protocol, which allows any device from any type to be plugged into a smart house network. We have recently extended xAAL to allow any ROS-compatible robot to be integrated into the smart house network. We illustrate the relevance of this framework in an implemented use case: assistance of an elderly person in the case of a fall (Fig. 1).
