Now that the Firebase Realtime Database is created, you’ll learn how to interface the ESP32 with the database. Program the ESP32 to Interface with Firebase Now, you have everything ready to interface the ESP32 with the database. Copy the API Key to a safe place because you’ll need it later.To get your project’s API key, on the left sidebar click on Project Settings.Now, you also need to get your project API key. You need to copy and save the database URL-highlighted in the following image-because you’ll need it later in your ESP32 code. In later tutorials you’ll learn how to secure your database using database rules. For testing purposes, select Start in test mode. Set up security rules for your database.It should be the closest to your location. On the left sidebar click on Realtime Database and then, click on Create Database.Follow the next steps to create the database.

The next step is creating a Realtime Database for your project. For testing purposes, we can select the Anonymous user (require authentication without requiring users to sign in first by creating temporary anonymous accounts).There are several authentication methods like email and password, Google Account, Facebook account, and others.On the left sidebar, click on Authentication and then on Get started.Knowing a user’s identity allows an app to securely save user data in the cloud and provide the same personalized experience across all of the user’s devices.” To learn more about the authentication methods, you can read the documentation. In other words, it takes care of logging in and identify the users (in this case, the ESP32). “Most apps need to know the identity of a user. You need to set authentication methods for your app. You’ll be redirected to your Project console page.It will take a few seconds setting up your project.Disable the option Enable Google Analytics for this project as it is not needed and click Create project.Give a name to your project, for example: ESP32 Firebase Demo.Click Get Started, and then Add project to create a new project.Go to Firebase and sign in using a Google Account.Set Up a Firebase Account and Create a New Project 1.Create a New Projectįollow the next instructions to create a new project on Firebase. ESP32: Read data from the Firebase Realtime Database.ESP32: Store data to the Firebase Realtime Database.This tutorial is divided into three sections. Then, you’ll program the ESP32 to store and read data from the database. To follow this project, first, you need to set up a Firebase project and create a realtime database for that project.

In this tutorial, you’ll learn how to create a Firebase project with a realtime database and store and read data from the database using the ESP32.

This means that you can have two ESP32 boards in different networks, with one board storing data and the other board reading the most recent data, for example.

The ESP32 can interact with the database from anywhere in the world as long as it is connected to the internet. In this tutorial, we’ll create a Firebase project with a realtime database, and we’ll use the ESP32 to store and read data from the database. You can use the ESP32 to connect and interact with your Firebase project, and you can create applications to control the ESP32 via Firebase from anywhere in the world. This paragraph was taken from this article, and we recommend that you read that article if you want to understand better what firebase is and what it allows you to do. The services are hosted in the cloud and scale with little to no effort on the part of the developer.” This includes things like analytics, authentication, databases, configuration, file storage, push messaging, and the list goes on. “ Firebase is a toolset to “build, improve, and grow your app”, and the tools it gives you cover a large portion of the services that developers would normally have to build themselves but don’t really want to build because they’d rather be focusing on the app experience itself. The following paragraph clearly explains the advantages of using Firebase: It has many services used to manage data from any android, IOS, or web application. Firebase is Google’s mobile application development platform that helps you build, improve, and grow your app.
