How to Control IoT Devices? A Step-by-Step Guide

What are IoT Devices?

IoT (Internet of Things) devices are physical objects embedded with sensors, processors, and software that connect to the internet. These devices collect and exchange data, allowing them to interact with their environment and other devices.

They typically contain sensors that measure light, temperature, motion, or other environmental factors. This data is then transmitted wirelessly to a network or smartphone app. This information is then used for remote management and monitoring (RMM), like checking on a smart home security system. IoT devices can also be programmed for automated responses. For instance, a smart thermostat can adjust the temperature based on pre-set preferences.

From fitness trackers to smart speakers, IoT devices are becoming increasingly common. They are even used in industries like healthcare and agriculture to create automation and improve efficiency. However, with this growth comes the critical need for robust security measures to safeguard the data these devices collect.

How Does IoT Device Control Work?

IoT device control relies on a network of communication between the device, a user interface, and often a cloud platform. Here's how it works:

  • Device Sensors and Processing - IoT devices are equipped with sensors that gather data about their environment. This data can be temperature readings from a smart thermostat, motion detection from a security camera, or activity tracking from a fitness band. The device also has a built-in processor that analyzes this raw data and prepares it for transmission.
  • Connectivity - Most IoT devices connect to the internet wirelessly using protocols like Wi-Fi, Bluetooth, or cellular networks. This connection allows the device to send the processed data to a designated platform.
  • User Interface (App or Web Platform) - Users interact with IoT devices through user-friendly interfaces like smartphone apps or web platforms. These interfaces typically display data collected by the device, allowing users to monitor its status (e.g., room temperature) or view captured footage (e.g., security camera feed).
  • Cloud Platform - Many IoT devices connect to a cloud platform, an IoT remote monitoring server that stores and manages device data. The cloud platform can perform tasks like data analysis, generating insights, or sending control commands back to the device.
  • Control Commands - Through the user interface, users can send control instructions to the device. This might involve setting a desired temperature for a smart thermostat, turning on a smart light bulb, or initiating a recording on a security camera. These commands are converted into signals the device can understand and translate into actions.
  • Device Action - Once received, the control commands are processed by the device's internal software. The device then takes the necessary action based on the instructions, like adjusting its internal settings (thermostat) or activating its functionalities (light bulb recording).

IoT device control is a collaborative effort between sensors, processors, communication protocols, user interfaces, and sometimes cloud platforms, enabling users to interact with and manage these devices remotely.

10 Ways to Control IoT Devices

Here are 10 methods for managing Internet of Things devices remotely:

Mobile Applications

Smartphone apps act as a remote control center for many IoT devices.

This provides a user-friendly interface for managing your IoT devices from anywhere with an internet connection.

Web Interfaces

Web interfaces provide another way to control IoT devices remotely. You can access a web dashboard through any internet browser on your computer or tablet. This dashboard displays device data and allows you to send control commands, similar to smartphone apps. It offers flexibility by letting you manage your IoT ecosystem from any web-enabled device.

Web Dashboards

Web dashboards function as control centers for IoT devices accessible through a web browser. These dashboards display data collected by the devices (like temperature) and offer controls (like adjusting a thermostat). This browser-based approach allows you to manage your IoT network from any device with internet access, providing flexibility for remote control.

Voice Control

Voice assistants like Amazon Alexa or Google Assistant enable hands-free control of IoT devices. By issuing spoken commands (e.g., "turn on lights"), you can interact with your devices. The voice assistant relays these commands to the appropriate device via a cloud platform, allowing for convenient voice-activated control of your smart home.


Near Field Communication (NFC) allows for short-range control of IoT devices. By tapping an NFC-enabled smartphone or device tag on a compatible IoT device, you can trigger actions or exchange data. This can be useful for the secure pairing of new devices, sharing configuration settings, or initiating specific functions with a simple tap.


Bluetooth provides a low-power, short-range connection for controlling IoT devices. Your smartphone or tablet can wirelessly connect to nearby IoT devices via Bluetooth. This allows you to send control commands (e.g., adjust lighting) and receive data (e.g., sensor readings) directly between the devices, offering a convenient way to manage your smart home without needing an internet connection.


Automation allows IoT devices to operate without manual intervention. You can pre-program rules or scenarios. For instance, a smart thermostat can automatically adjust temperature based on time of day or sensor readings. This removes the need for constant manual control and creates a more responsive and efficient IoT environment.

Integration of Third-Party-Services via API

APIs (Application Programming Interfaces) enable integration of external services for IoT control. Imagine connecting your smart lock with a ride-sharing app. An API allows the ride-sharing app to send a signal to your lock to unlock the door upon arrival, all through pre-programmed commands. This opens possibilities for creating custom control scenarios using various third-party services.

Physical Control

Many IoT devices still feature physical controls for direct interaction. Buttons, switches, or touchscreens located on the device itself allow users to adjust settings or activate functions without needing a smartphone app or web interface. This offers a familiar and immediate way to control the basic functionalities of the device.

Remote Control Protocol

Remote control protocols act like a language for IoT devices. Protocols like MQTT or Zigbee define how devices communicate with a network or app. These protocols dictate how data is formatted and transmitted, ensuring devices understand each other. This enables seamless communication and control between your smartphone and your smart lights, for instance.
