We propose in this paper a model to programme agents for ambient intelligence in which ambient agents are capable to compose their functionnalities for task achievement. More precisely, we present an interaction protocol that allows agents to compose functionnalities, provided by the services they offer, through a dialogue game and without any prior knowledge about the other agents. This protocol enables agents to answer to received messages, according not only to their capabilities, but also to their role in the interaction they are involved into. We illustrate the behaviour of this interaction protocol through a scenario involving agent-based home appliances.
