This article explains some technical aspects related to smart houses, as a group of new technologies is being incorporated to Spanish homes. It must not be forgotten that they should be adapted to users, as without them they would not have any meaning. It should also be reminded that automation is just another step in the evolution of houses. The different technical concepts included in this term are exposed in this context; this could help to determine precisely and exactly its definition , recently included by the Spanish Royal Academy of Language in its dictionary, and it may be applied to a classification of materials and products used in home systems, to check their performances. At the end, some of the possibilities and limitations of smart house&#226;&#128;&#153;s technologies in Spain are explained.<br><br>Este art&#237;culo va a abordar brevemente algunos aspectos t&#233;cnicos de la &#194;&#171;Dom&#243;tica&#194;&#187;, un conjunto de nuevas tecnolog&#237;as que se est&#225;n incorporando ya a los hogares en Espa&#241;a, sin olvidar que deben adecuarse a unos usuarios sin los que no tendr&#237;an mucho sentido y recordando que la automatizaci&#243;n de la vivienda es s&#243;lo un paso m&#225;s en su evoluci&#243;n. Desde este contexto, se plantea una visi&#243;n de los distintos conceptos t&#233;cnicos incluidos en este nuevo t&#233;rmino, incorporado recientemente por la Real Academia Espa&#241;ola a su diccionario, que podr&#237;an ayudar a precisar y delimitar su definici&#243;n, y que puede aplicarse a la clasificaci&#243;n de tipos de materiales y productos para su estudio, que permitir&#237;a posteriormente comprobar su integraci&#243;n en distintos sistemas dom&#243;ticos. Finalmente se plantean algunas de las posibilidades y limitaciones de la dom&#243;tica en Espa&#241;a.
