Today I took my first steps with Node-RED on my Victron system. Node-RED itself installed just fine and it seems to work ok. However, I can not get the Dashboard function to work. I keep getting the error message “Cannot GET /dashboard”.
Apparently others also have this problem, found some possible solutions on the internet. However none of these work in my case for some reason. There is a reference to the issue in this Node-RED for dummies topic, but I can not access the other topic that the author refers to because it is private or does not exist anymore.
I don’t remember the details but thanks to this forum, I think I used a couple of dashboard 2.0 (the latest at the time) fake/dummy text nodes that do absolutely nothing. I didn’t have to install the nodes separately or do anything extra.
Thanks, tried that as well. Don’t know if the flow type matters, but I made a couple of very basic flows with some inject/delay/debug nodes. Same result.
Dash 2 needs to be configured initially.
Can confirm it is working fine, it is all I use and version updates have not broken it.
You have likely missed a setup step to initialise it.
I had the same problem. When I logged in with 192.168.8.xxx:1881/Dashboard/Page1 the response was Cannot get /Dashboard. When I enter the address as https://192.168.8.xxx:1881/dashboard/page1 then the dashboard loads correctly. I am using Mac OS and Safari so it may be different with another operating system or browser.
Ok, thanks. Not sure what I missed then, executed the Node-RED installation steps mentioned in the Victron guide. According to this guide (but also the generic Node-RED one), installing the dashboard only requires the installation of the Flowfuse Dashboard 2.0 package using the Manage Palette menu.
There are some configuration files, but the Victron guide states that “the vast majority of systems using Node-RED will not, and should not (!), have to modify any of the files here described”. So I didn’t touch those.
I get the same error message when trying to access the dashboard via the VRM Portal and locally with the Cerbo IP address on port 1881.
Do you have a flow operating? If there are no deployed flows then dashboard does not operate. If there is no flows yet try putting a flow of battery voltage from whatever Victron source is available link that with say the Dashboard 2.0 Text Input Node, deploy and then view the dashboard from within the node red edit screen.
Node-RED works fine as far as I can see, but I just started using it so I can’t be sure. The problem is with the dashboard function, that doesn’t work at all. Every time I try to start it (either from the VRM Portal or by accessing the local IP address) I get the error message “Cannot GET /dashboard”.
Tried all suggestions given above by our Community colleagues.
On my NR workspace, I see Dashboard 2.0 nodes, among others, including Victron nodes. Do you see the form and text input nodes, as in the screenshot? Ignore the nodes on the right, that is the useless stuff.
Well, that was indeed the problem. Very logical once you know it. My reasoning was that the dashboard function can be started right after installing it, but that’s not the case.
