To install: Install node-red. Install this package with “npm install node-red-contrib-google-home-notify –save” in ~./node-red or via the Palette Manager in node-red. If everything was successfull you should see a new node in the output category in node-red after a restart.
How do I make nodes flow red?
If using Node-RED running on your computer, you can use http://127.0.0.1:1880 or whichever address or hostname you’re using. If you haven’t used Node-RED before, there should be one empty flow named Flow 1. From the node palette on the left side of the Node-RED editor, select an Inject node and drag it onto the flow.
While Node-RED really shines for IoT workloads with the ability to run on devices like the Raspberry Pi, it can also be run on laptop and cloud environments for any event-driven application scenario.
What is Node-RED Flow?
Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things. Node-RED provides a web browser-based flow editor, which can be used to create JavaScript functions.js.

What is Subflow in Node-RED?
A subflow is a collection of nodes that are collapsed into a single node in the workspace. They can be used to reduce some visual complexity of a flow, or to package up a group of nodes as a reusable flow used in multiple places. Once created, the subflow is added to the palette of available nodes.
How do I connect to Nodejs red?

What is Node-RED and how do you use it?
Node-RED is a programming tool for wiring together hardware devices, APIs and online services in new and interesting ways. It provides a browser-based editor that makes it easy to wire together flows using the wide range of nodes in the palette that can be deployed to its runtime in a single-click.
Why is it called Node-RED?
Why is it called Node-RED? The name was a light-hearted play on words sounding like ‘Code Red’. It stuck and was a great improvement on whatever it was called in the first few days. The ‘Node’ part reflects both the flow/node programming model as well as the underlying Node.
How do I start Node-RED in Home Assistant?
The first thing you need to do is install the Node-RED add-on so open Home Assistant go to Hass.io, Add-on Store, select Node-RED and then click on Install. When the installation finish, go to Config and under credential_secret set up a password that would be used for encryption.
Should I use Node-RED Home Assistant?
Node-RED is a very powerful and visual node-based tool for visual programming.Using Node-RED you can create highly complex and really smart automations with a lot of conditions, forks, and details using the visual editor. Node-RED makes this possible whereas Home Assistant automations would struggle.
What is Home Assistant Io?
www.home-assistant.io. Home Assistant is a free and open-source software for home automation that is designed to be the central control system for smart home devices with focus on local control and privacy.
What is Subflows?
Subflows are a sequence of reusable actions to use in a flow. Developers can create subflows to perform common processes specific to a custom application. Subflows consist of: Subflow inputs to pass variables to the actions in the subflow. A sequence of actions, flow logic, and subflows.
What are Subflows and when should you use them?
You define a subflow to provide a common sequence of actions to be used by several message flows, applications, or integration services. You can include subflows in your message flows in the same way as you include built-in or user-defined nodes. You can also connect subflows to other nodes in the same way.
What is node in Node-RED?

Why do we need Node-RED?
Node-RED allows you to create functionality by wiring together flows of data between nodes using a browser. And it has gained tremendous popularity in the IoT space, by modeling bits of application functionality between IoT devices like sensors, cameras, and wireless routers.
What is the difference between NodeJS and Node-RED?
First, Node-RED is written in Javascript running on the NodeJS platform, while the Crosser Edge node is written in C# running on .Performance – The Crosser Edge node can process significantly more data on the same hardware platform. The actual number will depend on the use case but a 10x difference is not uncommon.
