@paulvanderheijden90
Your node_helper.js is not correct.

Hello Sean,
Why is it wrong? I copy it from your post earlier.
I started in Dev mode. I noticed that wenn I add the Node_helper.js module in the MMM-P2000 map the Magic mirror crashes and give only black screen.
I studyed the Node_helper file. I see in the first line you define the function and in the second line you define the settings for that function. So that’s clear to me. In the next lines you define the stdout of the process and copy it in de Console Log. so that’s also clear for me. So I down’t know why is it not working and crashes.

I made in the same map ( home/pi/src/ ) a file called test.py Here I defined a string and I write the string to the stdout so as you say before the python project don’t need a separate call. So that should work as well.

Node_helper.js:

Python project:

I also getting in to the module setup so I changed the MMM-P2000.js and I think it is oke like this.
First the start function restart every 1000mS the dom function.
then the getdom Function is now showing the test “Hello World” in the module
so that should be oke aswell. I

How do I need to link the socked notification message to the Module string?

@sean
1.Try absolute path of your target py script.
( Oke I add the Path )

2.When your child_process.spawn is called, python script will be executed.
( oke that’s Clear.)

3 Well, node_helper.js is also needed. (* the codeYou send me I add in the node_helper.js.
3-1. Add your module into your config.js either. ( Yes I did. The example you send me was working. )
I can print something on the magic mirror on my own build Module.

4 When your python script is executed on the shell, normal stdout will be printed out on the shell.
( Yes this is working wenn I executed on the shell it will print what I give in so that site wil look fine.

So thank you for the answers. Im almost sure the Python project is oke. because it wil “print” thrue the sys.stdout.write function.
This is the Node_helper.js . I think this is fine aswell.

This is the MMM_. Module. im not sure I did this one oke.

And ofcourse I add the config. file.

Can you Please have a look what is going wrong because my magic mirror is now black and I can only restart bij ctrl alt del. so please help.

@sean
Again Thank you very much for this information. Im getting there with the code and learning bij Trail and Error ;)
I have made my own working module but still had some Questions.

1. The .py project is in the map src/ How do I fill in that it is there? Ore is this enough ?
   var process = spawn(‘python’,[“P2000Raw.py”]);

2. Do I need to run the Python project aswell ? or is then node_helper.js running it ?

3. I made this in the module but is looks like it is not working… :(
   

4. I add this to my code to test. it is seems to work. Can you please check if this stdout is ok?

Hello Sean,
Thank you very much for your replay. But can you be more specific over the module I need to use?
