Why Do the Internet of Things and Smart Homes Matter?
Published: 13 Dec 2025
Houses connected via the Internet of Things (IoT) allow for automated control of household applications, thereby adding efficiencies in terms of comfort, safety, and energy usage.
IoT uses environmental sensors to collect data, device controllers to activate actions based on this data, and communication hubs to unify the operation of various devices from different areas within the home. A smart home incorporates all of these IoT advancements to control light, heat, security, appliance operation, and energy consumption based upon predictable characteristics of the devices within it. Connected thermostats can reduce heating costs, and automated lighting systems can prevent unnecessary electricity usage. Consumers purchase IoT products to help them create energy-efficient routines, gain remote access, and maintain consistency in monitoring their homes. New protocols such as Matter and Zigbee will spur the growth of IoT products by enabling more devices from diverse manufacturers to work with each other.

What Is the Relationship Between the Internet of Things and Smart Homes?
The Internet of Things is connecting connected devices in homes and automating daily tasks using these connected devices in smart homes.
Motion, temperature, air quality, and energy consumption are all monitored in real-time by IoT sensors. Hubs receive these signals from the sensors and provide communication between the different connected devices via protocols such as Zigbee, Z-Wave, Wi-Fi, or Matter. The automation engine interprets events as they occur and creates automated routines that trigger smart lighting and other connected devices to behave as expected (for example, turning on or off at a certain time at the appropriate temperature).
Key triples
- Sensor → sends → motion or temperature data
- Hub → coordinates → device responses
- Automation engine → activates → routines and scenes
This relationship improves efficiency, increases security, and supports consistent energy control across the home.
How Does the Internet of Things and Smart Home Technology Work?
The Internet of Things (IoT) technology, used in smart homes, uses the connectivity of various devices to create a communication network between the different types of devices by utilizing wireless protocols.

FAQs
What makes IoT critical for building a functional smart home?
The Internet of Things (IoT) is an integral part of the entire infrastructure, integrating all devices, from sensors to hubs and controllers. An IoT solution can provide automation for lighting and climate control, security, and appliances by collecting real-time data, coordinating device operation, allowing for remote access, voice control, and multi-room automated controls.
How does a smart home improve energy efficiency through IoT?
Smart Homes utilize sensors and automated systems to reduce and adjust temperature, heating, and lighting based on time, temperature, and occupancy. Devices will maximize energy efficiency by reducing the amount of energy used when not needed (standby), scheduling tasks based on when the device is not busy, and identifying and eliminating other undesired energy usage (unnecessary consumption).
Are IoT smart homes secure, and what risks should users consider?
When connected devices utilise strong encryption, have updated firmware, and utilise authenticated access, smart IoT homes have higher levels of security. Most risks are created from weak passwords, outdated hardware, unencrypted information being transmitted over a network, and poorly secured or configured networks. It is recommended to utilise secure routers and perform frequent updates to mitigate vulnerabilities.
Which wireless protocol is best for IoT smart home devices?
Matter increases cross-brand compatibility. Zigbee has a focus on low-power devices (sensors). Z-Wave focuses on stable mesh networks and Wi-Fi 6 supports high-bandwidth devices. The optimal communication protocol is contingent upon the type of device(s), power requirements and physical configuration of the home(s).
Do IoT smart home devices work during internet outages?
When hubs can process locally, many automations are functional during outages, and local routines react to events related to light, temperature, or security. However, any automations that rely on the Internet or the cloud (including things such as remote access, voice assistant, and cloud back up) will not work until an Internet connection is restored.
How can users secure their IoT smart home?
By encrypting their smart home devices, setting individual passwords, updating firmware frequently, creating unique networks for their IoT devices, disabling unused ports, and selecting secure devices, consumers can protect themselves. Users can also reduce exposure to cloud threats through local processing.
