Could 2014 Be The Year Of Smart-home?

Popularity
            The popularity of smart-home has been increasing greatly in recent years due to much higher affordability and simplicity through smartphone and tablet connectivity. The concept of the “Internet of Things” has tied in closely with the popularisation of home automation. I think 2014 is the year smart-home gets serious. The whole idea of a ‘smart-home’ feels like a mythical concept people have been talking about for years. We’ve been seeing a smattering of smart appliances and other curios in recent years but it’s finally starting to feel like 2014 could be the year all this talk turns into something more meaningful. Here are some reasons why:
1.)   Rising energy prices and improving technology intersect.
Just like how I said it above that a smart-home may provide improved energy efficiency, energy prices are soaring and that makes selling the idea of smart-home, particularly money-saving gadgets that can help save money by switching off appliances when the smart-home system detects that no one is in a particular room or at home that much easier.
2.)   Huge smartphone penetration makes it accessible to everyone.
As I have said above, the popularity of smart-home has been increasing greatly in recent years due to much higher simplicity through smartphone and tablet connectivity. There are smart-home systems on the market that uses mobile apps to track each household member’s smartphone location and acts accordingly, such as turning the air-conditioning down when everyone is out and turning it back on when it detects someone is nearing home. Again, it makes things more efficient, and accurate at the same time. This is a very simple and neat idea, but one that would never have been possible even three or four years ago. With smartphone penetration in developed countries now so high, such systems have far fewer barriers to entry than before.
If you have a smartphone then you can have home automation, and most households have one for every person (sometimes more).
3.)   Wearable tech will open up new possibilities.
Wearable tech is everywhere at the various tech shows this year. There’s a smattering of smartwatches, a wee sprinkle of smart-eye-wears and dozens upon dozens of fitness trackers (at least in first-world countries). Next year will clearly be the year of smart pants…
Continuing this unedifying thought for a moment, one thing smartwatches and many other wearables would have in common with smart pants if they existed is they’re not very useful. So far the big idea on smartwatches is… smartphone notifications. I don’t need more notifications – they need to diminish, not be amplified. Fitness gadgets have a little more potential, but the whole area feels a little bit like a solution to a problem that doesn’t exist.
But smart-home has a lot of potential to change this. It’s clearly something Samsung has thought about given its smart-home initiative name checks its woeful smartwatch – who knows it could with something useful to do. I’ll get into Samsung’s role in all of this in a moment…
Thinking a little more broadly first, though, imagine what could be achieved with more intimate, sophisticated wearable tech? Why not control air-conditioning based not just on the ambient temperature, but on thee measured body temperature of occupants? Could wearable tech alert their users to fires when they’re sleeping (linking with something like a smoke alarm), or suggest what to eat based on blood sugar levels (linking into your smart fridge, of course)?
I’m just spit-balling here, but the more you think about it, the more interesting the possible combinations between home automation systems and wearable devices become.
4.)   Samsung can ‘complete the circle’ of connected devices.
And now we return to Samsung, which is the only company (with the possible exception of LG) that can claim to produce products in almost every important category across consumer and home electronics. It makes washing machines, laptops, fridges, mobile phones, smartwatches, microwave ovens, tablets… It makes a hell of a lot of stuff.
This puts it in the unique position of being able to create its own closed loop, a closed ecosystem much like Apple enjoys with iOS and Max OS. Apple shows that such a system can be very lucrative indeed, and Samsung has made a few moves to suggest it sees a future beyond its dependence on Android in mobile.
5.)   Apple MFi Certification is coming to home appliances.
Apple MFi is basically the program that results in the ubiquitous ‘Made for iPhone’ label. It’s an important mark for any product and Chinese brand Haier just became the first home appliance company to receive MFi Certification, in this case for an air-conditioner that could match the phone automatically and the user could set up parameters for the air-conditioner directly without registration, setup password or any other complicated and time-consuming operations when connected to WiFi.
Okay, so not exactly fully automatic and thus not truly smart, but is another small but important step towards a truly smart home as it isn’t exactly difficult to program the iPhone to work with wearables to achieve full automation. Haier also has plans to bring Apple MFi Certification to other products in its range, including ovens, water heaters and other “intelligent home accessories”. Samsung may hold an advantage within its own ecosystem, but clearly Apple can play in this arena as well.

6.)   Google is interested, could an open standard follow?
There’s some title-tattle to suggest that Google is tentatively experimenting in smart-home. Google is just too savvy a company not to realise how smart-home could further cement its ‘irreplaceable’ status in many people’s lives.
Google could, feasibly, play some part in ensuring an open standard for all this automation is created. There exist some standards for interconnecting things like lighting, but the likelihood is that any existing standard doesn’t have the scope to deal with the complexity future systems could require.
Given Samsung is one of the few companies that could create a closed system, it’s vital that open systems evolve so that people can tap into all this potential.

The opportunities of smart homes

Smart home has brought us many advantages to home users from automated devices to communicating devices away from home. In this blogpost I'll be talking about what will be the opportunities that smart homes can implement.

Cloud storage
With devices starting to communicate with users, where will all the data collected to be stored? What if every single day the data usage of a device reach to it's maximum and could not provide any further usage of the device? The solution to this problem is to implement cloud storage for the user. The advantage of having a cloud storage is to provide user another form of storage which do not require a physical storage to be stored in the internet. However these cumulative data is important thus encrypting the data is needed in order for these data to be stored in the cloud server.

Controlled temperature
We all know that smart homes do provide energy saving from turning on the heater or air-conditioner when hot or cold, but we have not heard the heater provide a certain temperature when we having a shower. What this means is that smart home should implement temperature control for our water heater during all the season, for example usually we love to have our bath approximately 35 degree Celsius. During the winter, the humidity of the air reduce thus the water become cold and heating the same temperature might not be 35 degree Celsius or might be hotter making it unstable. With controlled temperature, smart home users can set their preferable temperature throughout the entire four seasons

Home assistance
What sounds better than automation? Assistance. Imagine your house not only it is automated, it is guided with tools and technique. For example we just reached a new country and do not know what are the standard of noise pollution throughout the neighborhood, with smart home assistant we are able to detect the noise control and request the user to town it down or provide a barrier to reduce noise pollution. Smart home assistance can also help waste management better by providing a sensor to the dustbin and calls the garbage truck when the dustbin is full.

Health care manager
Everything will be much better if we get to take a look on how healthy we are, with the usage of telecommunication, we are capable of tracking the user's health and provide feedback to the user. For example a single device like a smart watch is worn by the user and goes for jogging, when he comes back he will be provided a summary of the exercise done and recommendation on what to eat for dinner. Wouldn't that promote healthier community? Also we usually live in the world of technologies where download rate is really important for us, why not when the user is exercising, the bandwidth increases. This will also promote healthier community.

Here are the report I've researched and came up with the opportunities of smart home hope you enjoy and provide feedback by commenting on the post.

Smart Home Networking Technology

One of the well-known brand for smart home network technology in United States are INSTEON. It uses a dual-band approach radio-frequency and power line. Video below shows how they works.

Why INSTEON is more reliable than other networking technology?

  • Uses separate hub to control the application instead of only rely on the modem router itself. A separate hub function to only transmit signal to applications installed in the house. Assuming that the transport layer using Transmission Control Protocol (TCP), the connection between the hub and applications will have a higher value of ssthresh. Thus, this give the capability of 16 millions devices to connect in a network.
  • Uses Mesh topology. Signal can be transmitted from many applications simultaneously and can withstand high traffic. Also uses peer-to-peer network. When one of the application fails, it will not affect the transmission of others.
  • Devices can connect in two ways either using Radio Wave of power line. Using power line will reduce interference compare with Radio Wave, interference such as distance between hub and devices, and other radio wave like phone signal maybe an obstacle. This may used up more transmission time need when interference happens.
  • All devices in the network act as two-way repeater. The protocol using hop count to optimized every device to decide connection. Furthermore, error detection and automatic error correction were also used in the protocol.
How the message being transmitted?

Example 1:
A Max Hops show how many time a sender or repeater re-transmit a message based on the repeater. Once a sender had transmitted a message, the repeater will listen to the message and re transmit to the next time slot.

Example 2:
In timeslot 1, Sender transmit message, repeater 1 and recipient  is listening. In timeslot 2, Sender and repeater will re-transmit to check whether there is another devices while recipient still listening. Until timeslot 3, sender and repeater 1 is in listen state means there they had meet the max hops then recipient show acknowledgement to the message sender has transmitted. Finally, recipient re-transmit the acknowledgement and pass through repeater 1 to re-transmit again to reach sender that this packet has confirmed receive by the recipient.

Finding

Although INSTEON provide reliability, but it does used up unwanted resource such as repeater to re-transmit message from source to destination. Each device function as a repeater in a network, thus if a network contain 50 devices, all the 50 devices help to re-transmit a same message from source to destination even-though the distance between source and destination only need one repeater is sufficient to transmit message from source to destination.

Smart Home

What is a Smart Home? A Smart Home can let user to monitor and control their house equipment function either automatically or remotely by smartphone or computer. A central unit will be placed in a smart home that connect all the electronic devices together and provide the functional over network for user to connect to their home when there is existing of internet on their devices. The image below shows one of an example from Vyrox that how does a Smart Home works.

Vyrox Smart House Concept Philosophy
Smart House bring benefits:
  • Home Automation - scheduled what you want to do by one touch
  • Home Surveillance - provide real-time monitoring when you miss your home through internet using any web enable devices
  • Home Security - able to receive notification immediately when someone enter the house and check alarm status
  • Home Appliances Control - able to switch on air-conditioner and set to a comfort temperature before reaching home
  • Lighting Control - automatically turn on the light when walking to the room
  • Lightning Design - change the light scene based on the atmosphere
  • Energy Saving - automatically turn of the light when the motion sensor did not sense any motion
  • Home Theater Control - centralized all the control in one remote controller namely TV, Astro, DVD player, sound system, etc using tablets.

Smart Home:The Backbone

The backbone of a smart home is a fast and stable broadband connection, as all your devices need to be able to communicate with each other and other services constantly. In the UK there is a great freedom of choice when it comes to internet providers with advancements in 4G technology and Fiber broadband means that in most cases there should be a good connection.
For rural areas, 4G is going to be a good driving force to help get a better connection, and hopefully more and more companies will continue to roll out fiber connections to more homes. As long as there is active connection, the devices will be able to communicate with all connected services.



CONNECTED APPLIANCES

In the next stage of creating the smart home, internet connected appliances that link with other services to fit into the overall connected smart home experience. Majority of the concept devices already exist such as washing machines and dishwashers that will alert you via text or email when their cycles are done, and fridges that will intelligently monitor their contents and alerts you when things are about to expire or have run out. It is expected that over the next few years we'll see a rapid increase in the availability of such appliances, as well as smaller appliances like toasters and kettles. Companies like Samsung, LG, SONY and others are all showing off their appliances of the future, there are expectations to be able to buy an entire smart home kit quite soon that will contain everything needed to set up a smart, connected home.

A SMART HOUSE

Other examples like this include smart windows and blinds that will automatically dim or shut when the light gets too bright or when the sun goes down. An extension of the entire smart home may involve a digital voice assistant such as Google Now and Siri. These could come in very handy for accomplishing smaller tasks - you could simply ask it "order some extra steaks for dinner tonight" and it will go online and order from your favorite supermarket. It's unlikely to be quite as smart as Jarvis from Ironman just yet, but given time it is possible in the future. We've talked about  devices and appliances, but what about the actual building itself? How can we make these smarter? Well adding things such as smart door locks that can lock and unlock with your phone, rather than needing a key. This can also enable you to unlock the doors remotely or grant temporary access for someone looking after the house while you're away. It will also keep track of who enters and when so you can be sure all your family is home safely. It's likely that paper-thin touchscreens will be on the walls as well, so that your whiteboard and calendar become a fully interactive screen that updates automatically and is always ready to send out that information to each family member's phone or other device.

STANDARDIZED CONNECTION

When talking about a smart, connected home, we often just look at the devices that are actually doing the controlling. However, perhaps more critical to the functioning of a smart and connected home are the services that allow the devices to speak with each other. At the moment, most smart devices each need their own app in order to control them from your phone, but ideally is to have one master app that can control all of them. Whilst this is easy to accomplish if all your devices come from one manufacturer, when you start to pick up devices from a range of different companies, things start to get a bit tricky. However, there doesn't appear to be a standard on the near horizon, hopefully one will come soon that will make it easier for to get our smart homes up and running.

A smart home is made up of lots of smaller components that create the connected whole, and even if you just have a few you'll enjoy the benefits. What excites you most about the future of smart homes? Let us know in the comments below!

Smart-home
The whole idea of a smart-home in my opinion is basically home automation, an automation of the home, housework or household activity. It may include centralised control of lighting, HVAC (heating, ventilation and air-conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security. Home automation for the elderly and disabled can provide increased quality of life for people who might otherwise require caregivers or institutional care.
I am into home automation, so I will chime in.
I think the ultimate goal for home automation is “automation.” My house should be able to respond to me, my family, and our movements/actions.

Introduction to Smart Homes

A Smart Home is comprised of collection of technical home automation concepts that are implemented and integrated together to meet certain goals and expectations of you, the client. A good job entails providing the highest quality of integration between the chosen 'Home Automation concepts' using products that are, by themselves as stand-alone products, well supported in the market and can be enhanced by cross-linking with other Smart Home systems.


Smart homes incorporate common devices that control features of the home. Originally, smart home technology was used to control environmental systems such as lighting and heating, but recently the use of smart technology has developed so that almost any electrical component within the house can be included in the system. Moreover, smart home technology does not simply turn devices on and off, it can monitor the internal environment and the activities that are being undertaken whilst the house is occupied. The result of these modifications to the technology is that a smart home can now monitor the activities of the occupant of a home, independently operate devices in set predefined patterns or independently, as the user requires.

Smart home technology uses many of the same devices that are used in assertive technology to build an environment in which many features in the home are automated and devices can communicate with each other. The below image shows the possibilities of what Smart Homes can achieve.
