Building Smart Homes with Raspberry Pi Zero

By: Marco Schwartz

Overview of this book

The release of the Raspberry Pi Zero has completely amazed the tech community. With the price, form factor, and being high on utility—the Raspberry Pi Zero is the perfect companion to support home automation projects and makes IoT even more accessible. With this book, you will be able to create and program home automation projects using the Raspberry Pi Zero board. The book will teach you how to build a thermostat that will automatically regulate the temperature in your home. Another important topic in home automation is controlling electrical appliances, and you will learn how to control LED Lights, lamps, and other electrical applications. Moving on, we will build a smart energy meter that can measure the power of the appliance, and you’ll learn how to switch it on and off. You’ll also see how to build simple security system, composed of alarms, a security camera, and motion detectors. At the end, you will integrate everything what you learned so far into a more complex project to automate the key aspects of your home. By the end, you will have deepened your knowledge of the Raspberry Pi Zero, and will know how to build autonomous home automation projects.

Integrating the modules into a single interface


Now that our modules are up and running, we are going to learn how to integrate everything into a single interface, so you will be able to run it on your computer or on another Raspberry Pi. You will then be able to control and monitor your smart home from a single interface.

We will first configure the server that will allow us to connect all the modules that we configured earlier. Then, we'll build an interface on top of that.

The code for the server starts by importing the required modules:

// Modules
var express = require('express');
var request = require('request');

// Express app
var app = express();

After that, this is where we'll define the IP addresses of the different modules in our home automation system:

// Raspberry Pi boards IP addresses
var motionSensorPi = "192.168.0.101:3000";
var sensorPi = "192.168.0.102:3000"
var lampPi = "192.168.0.103:3000"

We also need to define the pins on which the lamp and the motion sensor are connected...
