The market for smart home products is more crowded than ever, with several businesses vying to produce the next hip thing you should buy for your house. However, as a buyer, it could be challenging to pick a product when figuring out whether it will function with your setup or other things you might want to buy. Additionally, if a product doesn’t support HomeKit, such as a TV, you can usually find a cheaper model of that same TV that is a few years older. To be able to operate such gadgets from your phone, wouldn’t it be amazing if you could still add HomeKit support?
It is not surprising that as technology advanced, it started to touch everyday home goods in addition to our smartphones and other digital devices. Home automation app development is at an all-time high and only increasing with more than 258 million smart homes worldwide. According to Statista, the market for smart homes worldwide is expected to reach $75.44 billion by 2025.
But maybe your budget is tight, or you are in a mood to make your home become smarter by yourself? So here are some tricks with code and guide to make your own smart home using NodeJS.
How Does the Automation of Smart Homes Work?
You must understand exactly what a smart home is and how it operates in order to create your own smart home application. A typical “smart house” is a network of switches, sensors, and safety equipment that is managed by a central controller or a control panel installed on the wall.
According to that description, home automation is a system of physical and digital interfaces that link your smartphone or tablet to the Internet and other home appliances. In other words, users can start preparing coffee when they are miles away or switch on the lights in their flat with only a few taps on their phones. They can even plan an activity and see it happen repeatedly.
This procedure has two essential parts: automation and remote control. As simple as it sounds, remote control refers to the ability to operate items from a distance. Automation is the process of programming gadgets to switch on and off on their own.
The hub, which serves as the focal point of the entire system and is where all control is carried out, activates all linked objects. With a few touches on a smartphone screen, the user can therefore manage his own home’s components while at work or traveling.
What are the types of Smart Home Applications?
The quantity of services and features your app would enable should be considered while creating a smart home automation app. Two sizable categories of applications can be differentiated using this criterion:
- A one-purpose app:
This basically means applications for controlling one device or a homogeneous collection of devices. Apps developed for robot vacuum cleaners or lighting are examples of apps made specifically to track one technology.
- A multi-task app:
When you own several smart items, this one is more advantageous because it can support more devices. A multitasking app can manage whatever you add to it, including doors, lighting, cameras, and more. By getting rid of duplicate apps and establishing an unified environment for the devices, they contribute to reducing digital waste. Alarm.com estimates that 88% of smart device users who own homes would prefer to have a single multi-tasking app.
What are the Key Elements to Take into Account When Building Your Own Smart Home App?
With the aid of three key elements, having numerous devices connected to a single network that can be managed from your smartphone would prove to be most convenient in long term:
Changes in daylight, temperature, or movement are detected by sensors, and the system’s settings allow you to customize how these changes are handled.
Actuators are objects that can mechanically influence the control object, such as switches, valves, or motors.
Controllers are the tools used to operate features and send or receive signals from the system. It may be a PC, tablet, or your phone. It is sometimes referred to as a Central Hub and functions as the brain of the entire system, managing all smart items from one location.
