Multiple instances of node-red (Signalk)
Hi
With a normal node-red installation there is a way to run multiple instances (perhaps on different ports) of node red. With the Signalk version installed via the appstore the setup is slightly different. Is it possible to do this so I can, for instance, have completely different dashboards on different devices? If so can someone talk me through how to set it up or point me to where I can get this information?
Thanks

How to access node red dashboard without having to log in through signalk first.
The clue is in the title. Acording to that vague Gemini fellow it is "Modify httpNodeAuth property: Look for the "httpNodeAuth" setting and set it to false to disable authentication" ---but I can't find where this is. Yes I know that is very insecure, but if someone can hack into my network then they are welcome to query the level of my water tanks.
Alternatively, what is the preferred way?
And where is the node red settings file when installed by signalk?

Image folder for images for node red dashboard
Hello. I am trying to follow this guide about setting up an image folder for node red:
...
// When httpAdminRoot is used to move the UI to a different root path, the
// following property can be used to identify a directory of static content
// that should be served at http://localhost:1880/.
//httpStatic: '/home/nol/node-red-static/',
But all the posts relate to standard node red installations. I can't find how to set this up. I am experimenting with images in a ui_template and don't know/can't find where src="some_path" is on a Pi5
The URL of the image is: http://x.x.x.x:3000/plugins/signalk-node-red/redApi/ui/testimage.jpg
Any help?

Can someone talk me through Kip boolean control panel --> node red
Hello
I have tried hard to find an answer but I can't so I am asking here. I am trying to figure out how to get the Kip boolean control panel (actually the depricate dbutton/switch) into node red, ultimately so I can control some relays but for now all I want is to get a debug value in node red when I click a switch in Kip. From there I can set up everything else but I haven't seen an explanation of how to do this. I believe I need a signalk put handler but I can't see how to set up a path that is recognised in the Kip. Can someone help me out?

Node red Dashboard
Hi. I was trying to investigate node red dashboard and wondered what the correct URL for it was. If I create a button or gauge for example and deploy it how can I view it?
I thought it would be http://192.168.1.44:3000/plugins/signalk-node-red/redAdmin/ui/ but it comes up with a blank page. I must have missed something.

Setting up Kip for different devices
Hello
Is there somewhere I can find out how to set up different Kip dashboards for different devices. I understand I can set up different users and when they log in they get different layouts but I can't for the life of me work out how. It makes absolutely no sense to me how the storage works and I can't find any walkthrough or turorial/youtube video that explains it.

Trying to us GPIO in Node Red on Pi 5 has trashed my signalk
Hello
So I got node red working and wanted to use GPIO in node red on a Pi 5.
After following this post:
https://forums.raspberrypi.com/viewtopic.php?t=364182
And following the instructions to use GPIOD:
sudo apt install gpiod libgpiod-dev libgpiod-doc libnode-dev
node -v now gives me segmentation fault. Signalk no longer works and running it from command line (./signalk-server) gives segmentation fault. I have tried this on 2 different sd cards with Bookworm.
So the question is...has anybody got Node red accessing GPIO on a Pi 5, if so how. And how can I fix this?
What is needed to control GPIO in node red on a Pi 5?

Node red not loading
Hello. I was going to try to start learning how to use node red. When I click on the node red link in Webapps it just sits at "If your browser doesn't automatically go there within a few seconds, you may want to go to Node Red manually."
How might I go about finding what the problem is?

Signalk on Pi Zero 2w install hangs.
Ah.. Here you all are. I wondered where everyone had got to. I was wandering around the github discussion thinking it was awfully quiet and everyone is here having a party!
Anyway:
Hello
I have been trying to install Signal K on a pi zero 2, just for testing and as an experiment. I have got to the actual installation part (sudo npm install -g signalk-server) and it appears to have hung my Pi zero 2. I can ping the Pi but get no response from my SSH sessions. The CPU seems to max out at 100% and no mouse response if I connect a screen/mouse to the HDMI output. I have left it like that for several hours with no progress. I am running the installation in a screen. Any thoughts or options?
The last output from the installation is:
(node:2245) ExperimentalWarning: CommonJS module /usr/lib/node_modules/npm/node_modules/debug/src/node.js is loading ES Module /usr/lib/node_modules/npm/node_modules/supports-color/index.js using require(). Support for loading ES Module in require() is an experimental feature and might change at any time (Use node --trace-warnings ...to show where the warning was created) ⠙
The progress dots seem not to have changed either.
