Abstract. Although several newer technologies ex ist in the domotics market, one of the oldest remains extremely popular. Despite of its very Iimited functionality and performance, X I 0 is still a very common technology to manage simple Horne Networks. Even if other wired solutions such as KNX/EIB or LonWorks out perform XIO in every single aspect, they might still be a bit of an overkill when addressing simple needs in a modest Horne Network. However, XIO lacks support for wireless networks that could add a lot of functionality to its wired network. A good example would be how sensor networks could communicate with already existing XIO modules to allow full horne automation in, for example, light and shutter contra I. This paper will focus on the use of802.15.4 to add functionaIity to simple XIO networks, in particular how 802.15.4 could allow the use ofremote controls (or switches) acting over regular XIO modules, and how XIO switches can act over wireless modules using 802.15.4 as the transport layer. We will also see how 802.15.4 doesn't add complexity in the deployment and management of XIO Horne Networks, which is one of the reasons such an old technology remains popular.
