This editorial introduces the special issue Living with Smart Technologies: The Changing Dynamics of Digitalized Domesticity, which examines how digital technologies are becoming embedded in everyday domestic life and how they reconfigure its socio-cultural dynamics. Developed in connection with the SMARTUP project, the issue approaches the smart home not primarily as a technological artefact but rather as a socio-cultural phenomenon through which everyday domestic life, meanings, and power relations are reshaped. Bringing together the perspectives of sociology and cultural studies, the editorial foregrounds the challenges related to smart domesticity, the plural meanings of “smartness,” and the ways smart technologies intersect with axes of difference. In introducing the contributions, the editorial departs from technocentric accounts; instead, it asks how domestic technologies reorganize routines, household coordination, labor, and power relations at home. It also calls for a critical assessment of smartification beyond mere functionality. Such an assessment would remain attentive to the failures and trade-offs of smartification and to its capacity to unsettle assumptions about both homes and technology.
