The system has been applicable using normal home devices. Google Assistant gives natural language voice commands and with the help of an IFTTT app (If This Then That) the command of the Blynk app is decoded, and then in turn, is sent to the microcontroller. According to requests related to Google Assistant, to request the related relay or to turn on the related relay, the control relays are connected to it as per requirement. Used microcontroller NodeMCU (ESP8266) is Wi-Fi enabled. We establish communication between microcontroller and application via internet. ESP8266 is a low-cost Wi-Fi module available in market that makes project cheaper. The aim of this project is to develop a cheaper voice controlled home automation that gives the remotely control to the user of his/her home. Key Words: IoT, Google Assistant, IFTTT, Wi-Fi. 1. INTRODUCTION Home mechanized framework strategy is the capacity of the framework to begin or control home apparatuses or home gadgets utilizing remote sensor systems [1-2]. These days, accessible apparatus in the market is getting increment step by step as passed. Thus, more prominent consideration is being given to the control of such gadgets. In this paper, this structure is set up by the utilization of examinations and workplaces of the Internet of things (IoT) and embedded system. IFTTT is a web application, which gives triggering start with one server then onto the accompanying server. Blynk is an android application which gives an interface from apparatus by giving different sorts of gets and sliders. Google accomplice is a relationship of Google Inc. which is used to look or do changed assignments by fundamental voice headings. NodeMCU is a microcontroller chip which interfaces gear through the web using inbuilt Wi-Fi and gets bearing from the web and suits hardware. This structure interfaces the servers of Google right hand and Blynk App by using IFTTT. Google right-hand takes voice request also, offers to stand to the Blynk App through IFTTT. Blynk App sends information to the downsized scale controller chip NodeMCU ESP8266. NodeMCU accomplices with Relay, which switches the capacity to be streamed or stopped. 1.1 Problem Definition: Many of the automation systems have a limitation as  Explicit Range  Not open for everybody  Single client control  Unbound  Expensive Issue solution: -  The whole methodology is running on the web, so there is no fixed range between systems.  Wears down clear voice bearings, which can be set in any language so it is easy to access for everyone.  It can be controlled by different customers. Google right-hand unites with Google account and the different customer can get to that single record to control the system.  Without acknowledging Google record and the mystery word nobody can get to or control this system, so it is secure.  A solitary NodeMCU can control 16 apparatuses at once so it isn't so much expensive. 2. LITERARTURE REVIEW According to our study, there are many home computerization frameworks that exist and home gadgets are controlled utilizing android based telephone or tablet. Each module has its own novel highlights. At this moment a couple of associations are legitimately selected and are endeavoring to give better home computerization structure features. N. Sriskanthan [8] talked about the home computerization module utilizing Bluetooth by means of PC. In any case, this model does not bolster portable innovation. Muhammad Izhar Ramli [9] built up a model of controlled electrical gadgets framework utilizing Web. On the off chance that the server's status is underneath, at that point they set the server with auto restart. Hassan[3] has developed a telephone and PIC remote control contraption to control the devices, stick check figuring has been displayed, where it was with connection mastermind yet there was no remote correspondence.
