Google Assistant Based Voice Control Home Automation


This paper presents the event of a sensible home using Google’s assistant and smart home device descriptions and standard practices for demand response and load management? Smart Energy? applications needed in smart energy. The concept behind this can be to manage home devices with voice. On the market, there are several devices accessible to try and do that. However, creating your own is awe-inspiring. Build your personal assistant which will do the work for you. Simply your assistant needs voice commands. during this project single board pc i.e. Nodemcu ESP8266 is employed which has made a Blynk application account then linked to the IFTTT website then added to Google Assistant for voice commands. During this home automation appliances like Bulb, fans and Motor are used which might be management simply victimization Google help from the voice control. Here we’ll install Google help within the Nodemcu ESP8266 and the mobile is going to be hooked up with a microphone that takes all the voice commands through that it’ll mechanically manage the house alliances. Because the user provides the voice command to the microphone the house appliances will be switched ON/OFF consequently. They can use MQTT to effectively deliver solutions for a variety of areas including consumer electronic device control, energy management, efficient home and commercial building home automation as well as home energy management. If the CT and PT values will be increased the alert message will be sent to a particular person using MQTT


The idea behind this can be to control home devices with voice. On the market, there is a unit several devices out there to try and do that. However, creating your own is awful. Build your personal assistant that may do the work for you. Simply your assistant needs voice commands. Consistent with voice command home appliances can switch ON/OFF.

The world faced the biggest problem of power because the production of electrical power is less than the demand power of the consumer side. In many countries, the increased demand is growing at a faster rate than transmission capacity and also the cost of providing power is also increasing due to the higher coal prices and deficiency of fuel. Also, the reason for not getting the full power to the consumer’s side is the growing population of countries. To overcome the problem of power distribution this paper provides an overview of wireless sensor networks by managing the equal power distribution by using MQTT.

Exiting system:

    • It can be to control home devices with a switch
    • In the existing system, we have used wired communication for further information sharing.
    • The time-Based load controlling (ON/OFF) method will be used in the existing system
    • In a common node, all the information is fetched and analyzed

        Proposed System

        • In this planned system, Nodemcu ESP8266i is put in with a Blynk application account with the IFTTT website and then added to Google Assistant for voice commands. Voice command controls the house appliances.
        • The system is developed based on the MQTT internet protocol.
        • The main controller transmits the information received to the data node through MQTT.

        Block Diagram Explanation

        Nodemcu ESp8266 is linked with the Blink application account with the IFTTT website which is connected to the Google assistance cloud. Home appliances like BULB, FAN, and MOTOR are connected to the Nodemcu ESP8266. The current and potential transformer can be used to measure the current and voltage value and monitor to IFTTT cloud. If the CT and PT value has increased, then the alert message will be sent to a particular person using MQTT.

        Hardware Required

        • Nodemcu?
        • Bulb
        • Fan
        • CT(current transformer)
        • PT(potential transformer)

        Software Required

        • Arduino IDE
        • Google assistance
        • Language? Embedded C


        • Home automation
        • Industries automation
        • Hospital automation


        According to this system, a smart voice control home automation system is deployed into the Nodemcu ESP8266 using the Blynk App account with the IFTTT website and Google assistance API within it. Through which a user can home appliances just by giving the voice controls input.
