Resumen: Digital technologies have great impacts on all facets of human life at the home. This has also ethical consequences because technology acts as a mediator in the relationship between people and things, influencing the way we understand the reality and react to it. Ethics applies to people, not to robots or programs: ethical problems are met by users and, consequently, by designers and everyone involved in the production and dissemination of technologies. This chapter reviews the main ethical problems created by digital agents in the home, such as security, privacy, fairness, transparency, autonomy and sociability, and explains the channels through which ethical messages reach the people involved, in the form of codes of conduct and principles, with their potentialities and limitations, as well as the role of the virtues in the implementation of these principles.
