Creating a Connected Smart Home Prototype using the IoTivity

One of the most booming markets today in terms of technology and innovation is the use of “smart-devices” in order to create an interconnected ‘smart-home’.

A smart-home provides all the efficiency, practicality, and operability that you would need for your daily needs by making almost everything that you need to do accessible remotely, just like what PLC controls (see more about PLC Controls here – would do.

However, ever since its inception, one of the main problems of creating an actual smart home is the lack of “interoperability” between all the devices that you use. Whether you have a gas sensor or a Security camera system as part of your smart home, it can be difficult to get these devices working in cooperation with each other. This comes from the fact that when purchasing these smart devices, each of them might come with a different operating system and are remotely accessible from two separate devices (think of a remote TV and Washing machine but with two separate remotes). Because of this, the main goal of a smart home, which is to maximize efficiency and practicality is somewhat reduced. Thus, in order to circumvent this problem the OCF (aka Open Connectivity Foundation) was created.

Basically, the OCF provides the ability for multiple and different devices to “communicate with each other”, regardless of the difference of the manufacturer, operating system, and the chipset that all of these devices have. Basically, this process is done by simply using the cloud system in order to sync these devices using software and other programs. Below are some tips on how to create an interconnected smart home.

In order to create a connected smart home, the first thing that needs to be done is setting up your devices. Whether you have a smart air conditioner controller or some smart security cameras, this needs to be done. By setting up, this means installing the sensors, smart plugs, power meters, Wi-Fi, etc. that would be needed in order to create the connection between the devices and also, the devices themselves. After setting up the devices comes the task of creating the Home Gateway.

Basically, the Home gateway controls and monitors the devices (end devices) and monitors the consumption by reading data coming from a “smart power meter” by referencing an input/remote device. By this process, the remote device becomes able to monitor each of the separate devices together in one app/software and send out commands to them without the need of using multiple remote controls.

After setting up the Home gateway, installing the Smart power meter comes next. This device is a small device that lets it users to generate power from the sum (solar power) and conveys power data to Home gateway (how much power is saved, consumed, and stored), by conveying the data sent to it directly. Lastly, when everything is set up, the creation of an interconnected smart home would not be complete without “integrated system of controls”. In this case, this system of interconnected hardware is also known as the Web Portal. Much like any websites out there, the Web portal used by smart homes are connected to the Wi-Fi not only in order to monitor your devices but also to reference data to external software and integrate the controls together in one app.

More specifically, the Web portal is simply a site with which all the controls are out on either your laptop or your smart home.

As compared to other unconnected devices and technologies used today, both the PLC and the OCFs are indeed important in increasing the predictability and the efficiency of your day-to-day life. And since we have already given some tips in order to setup your own home, we hope that you could and try creating your own interconnected smart home.
