Build Status Coverage Status

Buy me a coffee

Various nodes to assist in setting up automation using Node-RED communicating with Home Assistant.

Project status

Project is going through active development and as such will probably have a few 'growing pain' bugs as well as node type, input, output and functionality changes. At this stage backwards compatibility between versions is not a main concern and a new version may mean you'll have to recreate certain nodes.

Getting Started

This assumes you have Node-RED already installed and working, if you need to install Node-RED see here.

NOTE: This requires at least Node.js v8.12.x and Node-RED v0.19.x.

Install via Node-RED Manage Palette


Install via npm

$ cd ~/.node-red
$ npm install node-red-contrib-home-assistant-websocket
# then restart node-red

For add-on users:

The Community add-on ships with this node right out of the box.

Under the server node config just check the checkbox for I use

The add-on can be found here:


Coming from a different version, e.g. @Ayapejian or @Spartan-II-117?

If you have been using @Ayapejian 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 @Spartan-II-117 fork this should be a drop in replacement.

Included Nodes

The installed nodes have more detailed information in the Node-RED info pane shown when the node is selected. Below is a quick summary

All Events - websocket

Listens for all types of events from home assistant with the ability to filter by event type

State Changed Event - websocket

Listens for only state_changed events from home assistant

State Trigger - websocket

Much like the State Changed Node however provides some advanced functionality around common automation use cases.

Poll State - websocket

Outputs the state of an entity at regular intervals, optionally also at startup and every time the entity changes if desired

Call Service - websocket

Sends a request to home assistant for any domain and service available ( light/turn_on, input_select/select_option, etc..)

Fire Event - http

Fire an event on the event bus

Current State - websocket

Fetches the last known state for any entity on input

Get Entities - websocket

Get entities based on search criteria with 3 different output options

Get History - http

Fetches HomeAssistant history on input

Get Template - http

Allows rendering of templates on input

Wait Until - websocket

When an input is received the node will wait until the condition is met or the timeout occurs then will pass on the last received message
