How Does Home Automation Work?

by 180Technologies

Home Automation is a concept that attempts to bring control of your everyday home electrical appliances to the tip of your finger, providing users with inexpensive lighting options, improved energy conservation, and optimal energy usage. Apart from lighting, the concept also includes having total control over your home security, as well as creating a centralised home entertainment system and much more. As the name implies, an Internet of Things (or IoT) based Home Automation system tries to control all of the equipment in your smart home via internet protocols or cloud computing.

The IoT-based Home Automation system has several benefits over wired systems, including ease of use, ease of installation, avoidance of the complexity of running through cables or weak electrical connections, easy problem detection and triggering, and, most all, mobility.

Basic Setup

An IoT-based Home Automation system is made up of servers and sensors. These servers are Internet-based remote servers that allow you to manage and process data without the need for individualised PCs. Multiple sensors put in the specified area may be controlled and monitored using internet-based servers.

Let’s take a closer look at how the many smart gadgets that make up the Home Automation system function together.

Controller: Your System’s Brain

Regardless matter whether you connect single or several sensors in your house, the main controller or hub is the most important aspect of your Home Automation system. The main controller, often known as the hub or gateway, is connected to your home router through an Ethernet wire. The centralised hub broadcasts and receives orders from all IoT-based sensors. The hub, in turn, accepts the input or sends the output to a cloud network that is accessible over the internet.

Smart Devices: Your Home’s Sensory Organs

IoT-based home automation consists of a number of smart devices that may be used for a variety of purposes such as lighting, security, and home entertainment. All of these devices are joined in a mesh network via a common network established by the gateway. This implies that consumers have the option of operating one sensor first, then the action of the other. For example, you may programme the living room lights to turn on whenever the door/windows sensor on your main door activates after 7 p.m.

As a result, via the main controller unit, all sensors in a shared network may execute cross-talk. Some smart sensors in home automation serve as sensor hubs, as indicated in the diagram. These are signal bouncer signal repeaters that are situated halfway between the hub installation location and the sensors that are located in a remote area. These sensor hubs are crucial because they allow easy signal transfer to sensors that are far away from the main controller but near to the sensor hub over such long distances. Smart Plugs are the most frequent sensor hubs in IoT-based Home Automation systems.

Internal Communication and Wireless Connectivity: How Does It Work?

The majority of today’s IoT-based Home Automation systems employ one of three wireless communication protocols: Wi-Fi, ZigBee, or Z-Wave.

A network ID is issued to the ZigBee and Z-Wave controllers, which is then disseminated to the other sensors in the network. The signals carried from the controller to the sensors and vice versa are communicated in a mesh topology, which means there is no set path for the signals. The signal from the controller will go to the target sensors either directly or through signal hops, depending on the availability of the quickest path. If any of the intermediate sensors along the path are busy or occupied, the signal will take a different course across the mesh network to reach its destination. It’s worth noting that sensors with various Network IDs can’t interact over the same channel.

Connected to the Cloud: Access Everything From Anywhere

The Cloud-based-Networking system entails data storage and management through the Internet. This provides consumers with the ability to access data from anywhere on the earth.

As a consequence, with IoT-based Home Automation systems, users may send orders to the hub from afar or from a remote place over the cloud network. The hub will then transmit a signal to the appropriate sensors, causing them to activate and carry out the user’s request. The hub will communicate the status of the action taken to the cloud network after it is completed, allowing users to control and monitor every element of their smart homes.
