What is a smart home?

• A true Smart Home is one that seeks to take full advantage of Smart technology within a wider, yet focused, specification allowing service providers and occupiers to benefit in many ways - from convenience and better living standards to energy saving and device communication.

BEAMA identify 4 types of Smart types for homes:

• LIFESTYLE smart home

• SAFE AND SECURE smart home

• ASSISTED LIVING smart home

• GREEN smart home

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

LIFESTYLE

• Distributed audio

• Distributed video

• Mood Lighting

• “Home cinema”

“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

“pick & mix” – a structured approach

• indentify requirement

– features and locations

• select supplier(s) & products

• planned installation

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


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

The Legrand home systems

Philosophy:

• minimal changes for installation

• plug & play approach to set up

• fit & forget philosophy

• aesthetics


“plug & play” from Legrand

• wide range of functions

• “pick & mix”

• functions auto linked to network

• easy “learn” process to create added features such as “scenarios”

Conclusion – what is available now

To meet the increasing call for systems in the home

• systems are available that are designed to be

– easy to install

– easy to use

– easy to maintain

– designed to integrate with the traditional electrical wiring accessories


Conclusion – importance of planning

• there is a need to identify what is really required in advance

• planning the installation and adequate infrastructure will:

– give flexibility

– be cost effective

– result in a successful installation


Conclusion – some hidden benefits

Often:

• it is possible to use the smart installation cable structure for a traditional installation

• smart lighting control systems remove the need to cable for two way and multi way requirements

• home systems contribute to energy saving – easier control of lighting, reduced pieces of audio / video equipment on stand by
