This guide is dedicated to getting you up and running with Homey App development within about 15 minutes. Even if you have no previous experience with the tools being used, this guide should have you covered.
You need Node.js to develop Homey Apps you can download the official Node.js installer from the Node.js website.
By installing Node.js you have gained access to the Node Package Manager (NPM). This is a command-line tool that manages dependencies of Node.js projects. NPM allows you to install Homey CLI with a single command.
The Homey command-line interface (CLI) is the tool you need for Homey App development. It enables you to create and run apps on Homey for development and debugging purposes. Additionally, it contains various utilities that make Homey App development faster and easier.
Open a command line and execute the following command. This installs the Homey CLI globally on your system and exposes the
npm install --global homey
After installing the Homey CLI you can use the
homey app create command to create a basic project directory for your Homey App. This command will start an interactive prompt that asks a few questions such as what the ID of your app should be.
homey app create
The ID of your app should be in "reverse domain name notation" so if you're creating a Homey App for
https://solarpanels.acme.org, the ID should be
After answering the questions the CLI will create a new Homey app in a directory named after your chosen Homey App ID. The rest of this guide expects that your current working directory is the Homey App folder so you should change your directory to it:
The project directory will contain a number of files and folders required for your Homey App to run on Homey. Don't be scared by this, you don't need to understand what all these files and folders mean at this point, we will explain the purpose of all the files and folders in the next section.
Now you should have a very basic Homey App automatically generated by Homey CLI. In order to see this basic app at work let's run it on a Homey. First, make sure that Homey is either:
directly connected to your PC/laptop over USB, or
connected to the same Wi-Fi network as the PC/laptop you are working on.
From within your Homey App project directory, run the following command to start uploading your Homey App to Homey.
homey app run
After you are logged in Homey CLI presents you with a list of available Homeys connected to your Athom account in the command-line window. Select the Homey on which you want to run the Homey App and it will start uploading and running automatically.
While the Homey App is running it will print debug logging to the command-line window. In order to quit running the Homey App, press
CTRL + C and it will be uninstalled.
A number of commands which might be useful are listed below:
Login with a different account using:
Switch to a different Homey using:
Run a Homey App in development mode without keeping your command-line window open:
homey app install
Publish a Homey App to the Homey App Store:
homey app publish
If you want to learn about all other functionalities provided by Homey CLI use the
--help flag to list all possible commands.
To see sub-commands, you can type:
homey app --help
You're off to a great start, after creating and running your Homey App there is a lot more to discover. Homey Apps can offer a lot of functionality for Homey users, for example with Flows and Devices. Continue reading The Basics to see what is possible and extend your Homey App to your liking.
