Hi, In my project I use multiple libraries that have access to external devices through IP address. The problem I got is that every time I need to change to another device that has different IP address I need to change multiple config nodes in the Node-RED editor itself. The solution that I would l…

Not directly what you asked for, but did you try using a hostname or fully qualified domain name instead of an IP address?

What node or nodes are you using?

I mainly use those libraries: node-red-contrib-sftp node-red-contrib-bigssh node-red-contrib-moonnode and possibly more to come as time goes by. All of those node configs need to be modify with needed IP address.

The nodes I'm using (list above) need to have IP address specified in order to connect. The devices I'm connecting to don't have domain name.

Perhaps using environment variables would solve the problem. You could set them either in the OS or in settings.js. Then it would need a node-red restart to implement them,.

Maybe I'm not that good at this stuff, I'm struggling to set it up correctly and I need your help. Do you refer to $env('ENV_VAR') or similar? What is the way of providing this inside config node? Should I use $env('ENV_VAR') or env.get("FOO") I have problems with both. I also tried functi…

Neither. See Using environment variables : Node-RED So when configuring a node, if you have an environment variable MYVAR you would put ${MYVAR}

I'm not having fun time with environmental variables, I tried using that, but is seems a little too much hustle to get the job done. Also environmental variables are differently access or set on different operating systems. In my case it's not the good solution for this problem. Still looking forwar…

That was the first thing I thought about, but in this case it will not work, since I need to be connected to multiple devices that are same brand, same model, everything is the same, only IP is different. The devices are also sometimes completely erased, so the last thing I want is to constantly con…
