The question I get asked most about Smart Homes is: “Can you quickly explain how it all works?” So today’s post is based on how I normally explain Smart Home technologies to those people.
I Hope it helps.
To understand the technology of the Smart Home, you need to think of it like any other technology stack. It is arranged in layers. For the Smart Home, this can be considered as a 3-layer set…
1) The Interface Layer.
This is where you as the smart home owner/user control, monitor and programmes the full range of Smart Home technologies within the Home. This interface layer may take on the form of a wall mounted touch panel. Or, as is becoming more common, a PC, tablet or smart phone, via an app or range of apps.
The interface layer also allows, those with the relevant skill set, the ability to write macros and programme their smart technologies to enhance their functionality.
2) The Controller Layer.
In any Smart Home, the controller is the hub of operations. It is the consolidated solution for unifying any connected ‘Things’ and controlling them from a one simple application. Many of the larger Smart Home suppliers provide a Controller of some sort.
The easiest way of thinking about it is, as a small, highly connected computer that specialises in providing access to, and controlling things. In fact, in some instances where a dedicated Smart Homes Controllers are not used, a PC can be slotted into his layer.
3) The Things Layer.
Things, as in the Internet of Things (or IoT), are the fun side of the technology set. In traditional IT terms they are the peripherals. The amount and range of which, are increasing every day. Things include: Lighting, Security, heating, comfort control, white-goods, etc. etc. The list goes on and on.
The level of integration each of these ‘Things’ brings to the smart home is device dependant. These could range from being pre-programmed, to controlled remotely, through to being set up as truly smart and being allowed to control themselves based on a set of pre-defined logic.
In a nutshell there you have it. A basic look at how Smart Home technology all hangs together.
