Abstract: Internet of Things (IoT) advancements have enabled smart home and industrial automation improvements, allowing gadgets in homes to be monitored and controlled remotely. Because appliances are monitored and controlled by small, resource restricted embedded devices, such systems have resulted in energy efficiency and cost savings. Using Message Queuing Telemetry Transport (MQTT) and Node-RED, the article offers a concept for an ESP8266 NodeMCU smart home solution. On the Raspberry Pi 4B, a single board computer development board, a MQTT mosquito broker is used in the smart home system design. A MQ2 sensor is connected to an ESP8266 microcontroller to collect the sensor data, with the Raspberry Pi acting as a MQTT broker to transfer sensor data to a Node-RED dashboard.

Key-words: Node-RED, MQTT, Home Automation
