I'm try to use one variable input on node.
in my case is a URL on websocket. the user set a URL of the websocket on the HMI, and de rapberry take the URL via modbus.
How i can create a variable on properties of the node, that can be modified any time.

What node are you using? Have you read the node's info?
Many nodes allow you to pass in parts of the msg that will define the option in the node.

i'm using the node-red-contrib.ocpp, this node don't have option for to put a variable, only fixed URL.
into the node, have any function that read a global variable of the dashboard?

You should be able to use the `$(environment variable)` syntax to set the field from an external environment variable, but this is only read at start time.

Might want to ask the node's author to add that ability

Search the flows library, I put an example out there awhile back

but when i read a env with global.get("env"), the function return empty value

i created a FOO variable, when i put on a topic in node properties, it ok, but how i set a value for this variable on my software?

(back on a decent keyboard)
You can set just about any field in a node to use an **external** environment variable by setting the field in the config like `$(env_var_name)` where env\_var\_name is the name of the variable so for example I could set (In Linux - outside of Node-RED) `export foo=192.168.1.10` then in Node-RED set that field to $(foo) and on deploy it will read that variable and use it...

which leads to a question for @glconceicao - what os are you running on?

I running node-red in Raspberry.
I was able to use the environment variable. i create this variable on node red setings, and then use this variable out and in on the blocks.
but now when start the program, how i use the websocket conection, the websock start before settings the environment variable, generating error on websocket. is it possible to create a delay to start the block?

Hmmmm if only there was a 'delay' node.....

But even if i use the delay node, the websocket opens befere, because it does not depend on the flow, i have to create a subroutine on the node, to delay websocket startup.

What is your flow? Can you post it? (don't forget to use three back tick's - ``` - before and after it)

this is my main flow, and the OCPP client is responsible to open the websocket. (node-red-contrib-ocpp)
i could not place the code because it is too big.

A picuter of the flow is not much help, why don't you export and save your flow, then strip it down to a managable size that still shws the problem and provide that flow.

so what ocpp node and what mobius node are you using?

the OCPP opens the websocket with de central system, and is the node that i have problem. becausa the websocket opens independent of the flow.
the modbus make de conection with the HMI.

I was looking for the actual name of the two nodes. There are a couple mobius nodes and OCPP nodes. By supplying the names of the nodes you installed, it may help debug the issue.
That said, not having eithor Mobius or an OCPP divide, I'll be stepping out of this conversation, but hopefully someone else looking at all the info will be able to help. Good luck.
