I have plain HA without docker, without hassio, on an ubuntu PC.
How can I connect it with node-red?
Install node-red then follow the instructions installing and configuring this:
https://zachowj.github.io/node-red-contrib-home-assistant-websocket/guide/#home-assistant-add-on
The documentation is very good
Oh ok, so it is this?
npm install node-red-contrib-home-assistant-websocket
Yes, that is it.
Now I did “sudo snap install node-red” so it does not install all the dependencies on the machine. Then I opened the URL http://localhost:1880 to get node-red.
In the node red settings I installed node-red-contrib-home-assistant-websocket.
Then you need this custom component: GitHub - zachowj/hass-node-red: Companion Component for node-red-contrib-home-assistant-websocket to help integrate Node-RED with Home Assistant Core
1.Install Home Assistant Core and Node-Red in a full raspbian environment.
1.1 Install Home Assistant Core
1.2Install node-red
sudo snap install node-red
2.set Node-Red to communicate with Home Assistant Core
2.1 Connecting Home-Assistant in Node-red
2.1.1 Install node-red-contrib-home-assistant-websocket.In the node red settings
2.1.2 Install Node-RED custom integration in Home Assistant
2.1.1 is a bit unclear, it didn’t find “Home Assistant” after doing just
npm install node-red-contrib-home-assistant-websocket
and restarting node-red
What i did need was
Manage pallette → Install tab → search “node-red-contrib-home-assistant-websocket” → Install
