IoT technologies continue to spread in our society. Nevertheless, there are still different critical point to be faced and solved. Among the many, given the ever-growing potential for action, a major issue concerns the autonomy of these devices. In this work, we propose a possible solution on how IoT devices may act in order to get more autonomy, in relation to the specific user they interface with. After introducing a theoretical model, we considered a possible implementation in a simulation context, showing how the proposed approach works.
