# Getting Started
Have Node-RED installed and working, if you need to install Node-RED see here.
# Using the Palette Manager
Search in the Palette Manager for:
# Using npm from the command line
$ cd ~/.node-red $ npm install node-red-contrib-home-assistant-websocket # restart Node-RED
# Home Assistant Add-on
The Community Home Assistant add-on ships with this set of nodes right out of the box and comes configured to connect to Home Assistant. No other information is needed and you're ready to start your first automation.
The add-on can be found here: https://github.com/hassio-addons/addon-node-red#readme
Place an Events: all node onto the workspace and edit the node. Click on the pencil icon next to the Server field.
Search for a local Home Assistant instance or manually fill in the Base Url.
Enter an Access Token on the server config node then Add/Update the Server Config and Events: all nodes and deploy. After deploying a green box with a status message, i.e. connected, stated_changed, should appear below the Events: all node. If you see an open box with the status of connecting or disconnected you probably have incorrectly entered the base URL or access token.
Base Url is the web address and port you use to access the Home Assistant frontend (e.g., http://localhost:8123, http://192.198.x.x, and http://example.duckdns.org).
Access Token is generated in Home Assistant there are instructions below on how to generate one.
Changing the deploy type to Modified Flows or Modified Nodes will make it so when you deploy only the flows that you have modified will get reloaded. This helps if you have other flows on the workspace that you don't want to have reloaded everything time you change something else.
If you find that new entities added to Home Assistant are not showing up in the
autocomplete results try unchecking
Cache Autocomplete Results in the
server config and restarting Node-RED.
# Generate Access Token
The user used to create the access token must be in the administrator group for this package to function correctly.
Goto your Home Assistant home page and in the bottom left corner click on the blue circle with the letter in it. In the screenshot below it's the "J".
- Scroll down to the bottom of the page and it should look like the screenshot below and click on the Create Token Button
- Give it a name, it can be anything you want to identify it
- Copy the generated access token into Node-RED
Creating a separate Home Assistant user for Node-RED and using their access token will give you the ability to track which entities were changed by Node-RED.
If you have been using node-red-contrib-home-assistant version there are some breaking changes with two of the nodes. The poll state and current state both have a little different formatted outputs. Check your nodes and make sure they are outputting what you expect. A more in-depth example can be found here.
If you have been using the node-red-contrib-home-assistant-llat fork this should be a drop-in replacement.
