Home Automation Systems- A Quick Guide

In this article, I will do my best to explain some of the basic concepts related to smart homes and home automation. It is easy to get excited about smart homes and just as easy to get bogged down in all of the confusing details.

After all, there are just so many different products and systems to get your head around…

And what do you know? As soon as you think you understand it all, out comes another product that seems to change it all!

This post will be split up into two neat sections:

[1] Protocols (also called systems or languages.)

[2] Hubs (also called controllers or relays)


The basis for any home automation is a shared protocol that a smart device and a smart hub have.

A protocol is a language (or a set of instructions) that enables devices and hubs to communicate with one another.

In this section, I will briefly explain about 4 protocols:

[1] Z-Wave

[2] Zigbee

[3] Belkin Wemo

[4] Apple HomeKit


Brief History

Z Wave is an alliance was created in 2005.

Is a Smart Hub or Controller Necessary?

Yes, a hub such as Wink, Insteon or SmartThings is necessary.

Number of Compatible Devices

Over 450 companies make thousands of Z Wave compatible devices

It is a wireless technology for smart home automation. Z-Wave is popular for its activities of automated lighting, security, and heating.

It supports a hub that can easily become a source of communication among 232 devices. Along with the increase in the connected devices, the signal length gets farther.

Moreover, this smart home solution is compatible with more than 1,500 devices and this means that it provides multiple options for keeping the communication. It offers strong security services via assigned unique IDs.


Brief History

Zigbee was launched in June 2005.

Is a Smart Hub or Controller Necessary?

Yes, a hub such as Wink, Insteon or SmartThings is necessary.

Number of Compatible Devices

I cannot find an exact number of devices or companies (that make compatible devices.)

Zigbee is an open technology that uses the “mesh” system for the interconnection and communication of smart devices.

It is used as a sensing and control mechanism in homes as it lets more and more automation devices to reach to each other via signals without the presence of some high power transmitters.

Due to its open technology, ZigBee is compatible with several devices and thus seamlessly integrates the gadgets connected.

However, it has some security issues as the settings may be vulnerable to the hackers.

The fact that it needs very little power with only one set of power is the biggest pro of this system that shows off its ease of setup, use, and maintenance.

Belkin Wemo

A Brief History

WeMo was founded in 2012 by Belkin.

It is Belkin’s Home Automation Arm.

Smart Hub/ Controller Necessary?

No. Because each device uses Wi-Fi to connect, each device connects to your home Wi-Fi.

Number of Compatible Devices

There are five WEMO products made by Belkin:

[1] Smart Plug [2] Mini Smart Plug [3] Dimmer [4] Light Switch [5] NetCam HD

In addition there lots of products out there that are compatible with the WEMO system, including smart coffee makers.

Belkin Wemo is offering a hands-free control over your automation system as you can simply communicate with your devices through Amazon Echo or Google Home without lifting your finger.

Apple HomeKit

A Brief History

HomeKit was mentioned when iOS 8 was released in June 2014 but the first HomeKit compatible products weren’t released until a year later.

Is a Smart Hub or Controller Necessary?

A smart hub isn’t necessary as devices can be controlled via an iPhone as long as the phone and the smart device are connected to the same Wi-Fi network.

However, if you want to access your devices when you are away from home, then you will need to buy an Apple TV.

Number of Compatible Devices

Well over 100 smart devices are compatible with Homekit.

HomeKit is the smart home controller that controls all of your compatible devices by giving you the satisfactory home automation experience.

It actually allows your smart home devices interact with each other, but the problem is not each device has all of the functions compatible with the Apple Homekit.

The integration of Siri has been around for quite a while and you can clearly operate devices with it. Siri is responsive and has been used by several home automation clients, so it has this competitive advantage over its rival packages. However, it is not as open up as others.

Smart Hubs

In the next section of this guide on home automation systems, I will explain more about smart hubs.

A smart hub or controller is a device that all other smart devices on the system must connect to in order to be part of the system.

In this section, I will describe the following hubs

[1] Samsung SmartThings

[2] Wink

[3] Insteon

[4] Apple HomePod

[5] Amazon Alexa

[6] Google Home

Is a Smart Hub/ Controller Necessary?

No, as the Echo is the hub.

Number of Compatible Devices

There are well over one hundred smart devices that are compatible with the Amazon Echo or are “Alexa Ready”

and this number is increasing at a very fast rate.

Amazon Alexa doesn’t integrate with any other smart home protocol.

It requires nothing but your voice in order to perform activities, like those of playing music, making shopping lists, getting weather and climate reports, searching the web, and turning on/off lights.

There are no activation buttons as all you have to utter is the word of either Amazon, Alexa, Echo or Computer, and then tell what you want to happen.

It responds to your commands by doing the activity as asked. This smart home control system is supported by the Echo’s far-field microphones that let it respond to the voice commands from any place within the earshot.

Google Home

A Brief History

It was in March 2016 that rumors started to circulate that Google was developing a speaker to compete against the Amazon Echo.

It was officially announced in May 2016 and was launched in the US in November 2016.

Is a Smart Hub/ Controller Necessary?

No, as Google Home is the hub.

Number of Compatible Devices

There are not as many compatible devices as the Amazon Echo but, like the Echo, the number of compatible devices is increasing rapidly.

It is another voice controlled smart speaker system that answers your questions with a better personality.

It has a Google’s virtual assistant that is more verbose than those on the smartphones. The top portion of the device is touch-sensitive and makes it easy to pause the music or cancel any current task if you don’t want to use your voice.

It gets activated from the wake words of “Hey Google” & “OK Google”, after that, you can ask anything from it to get the instant responses.

Google Home is Wi-Fi enabled so as far as you have the internet connection, the interactions remain consistent and the responses are instant.

I hope that this guide has helped your understanding about smart homes and home automation systems.

As time goes by, I will hopefully keep adding to this guide.
