Examples of smart(er) systems for homes
However:• implementation is not consistent• tends to be optional• demand for integration of the functions into a single system is current
limited• major demand is one of a “pick & mix” of functions

“pick & mix” approach - an installation chaos?
The “pick & mix” approach could lead to:
• a wide mix of wiring types and circuits
• multiple and confusing interfaces for the user
• unconsolidated technical support for the installer and end user

Home systems – a structured approach
• System products now available that:– require minimal specialist wiring circuits– greatly reduce the set up requirements during installation– are relatively intuitive for the user– are almost fit and forget in nature
© Legrand Electric Limited 2008 - S8
Categorising home systems
• stand alone functions ���� no interaction with other devices
• “plug & play” functions ���� self install with other functions on network
• integrated programmed network ���� various degree of programming required during installation to integrate number and diversity of functions
