First off I am very new at this. So please be kind. I had Node Red running on a Raspberry Pi and had a isssue so I did a clean install of the PI and Node Red. After that when I tried to launch the Node Red dashboard from my home PC like before I get the error Cannot GET /ui. I can get on XXX.XXX.XXX.XXX:1880 site.
I have spent hours searching for help online but nothing has helped.
I am using version 2.2.0 of Node-Red
Are you just using /ui or 192.169.1.nn:1880/ui? (Where 192.168.1.nn is the IP address of NR
Also did you install the dashboard?
Have you installed the
node-red-dashboard - node-red-dashboard (node) - Node-RED
and added some of the dashboard nodes to a flow?
If not, go to the palette, and you'll find it in the
This is a screenshot of what I have. If I need to install the Node Red dashboard I do not know how to do that.
Ok I did find out how to install the Node Red dashboard and successfully did that. It is working except when I a node tries to connect here is a screenshot
Paul when I went there nothing was there to choose from. Now there is. Do I need Mosquitto MQTT to make the node to connect.
Are you still trying to get the dashboard working, or are you now trying to use mqtt? If you want to use mqtt then you need a broker such as mosquito.
I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
Paul why do the payload settings keep reverting back to True and false when I try to set them to 1 and 0
As @Colin has said, you really need to spend a little time watching the Node-RED Essentials playlist to get a better understanding how node-RED works.
After that, if you have a problem, please start a new topic, and fully describe what the problem is, and what you have tried to solve it.
I did get the dashboard working. I just reinstalled it on the PI.
