MMM-Remote-Control API Questions

[sgarg15]

@Jopyth Hey so i was going through your MMM-Remote-Control API and i had some questions.
So i am trying to make a python script that detects a swiping motion to then change pages, but since this is a seperatte python script (not in a module), the MMM-pages module cant accept the notifications given to it.
So the creater of MMM-pages, told me if i had a look at your API i could possible achieve this. but after giving it a thorough read, i was having difficulty figuring it out.

So essentially i wanted something like this

def swiper():
  #code here to detect swipe
  if leftSwipe:
    #send a notification to pages to go left
  if rightSwipe:
    #send a notification to pages to go right

If you could help me achieve this, or give me some info that could help me do this i would really appreciate it

[sgarg15]

If anyone else who understands the API could help me out i would really appreaciate it as well @sdetweil

@sgarg15 so, you need a node_helper for the python script to send the notice to(as it can launch the python script and read the messages) and then the node helper can send the notification up to its modulename.js, which can then send the notification.

lots of modules work this way, PIR

MMM-Swipe does this exact thing, which is what I think u want to use

fork it, change the name, and modify the node_helper to launch your python script and accept your python messages

@sdetweil If possible could you please give me an example of how i would do it, i dont know much about js. and i looked at the MMM-Swipe but i couldnt understand much

[sdetweil]

@sgarg15 swipe isn’t a good example after all, uses a library which hides all that… nor PIR…

your python script needs to run forever and put out messages for each movement it sees…

then you use the nodejs Python_Shell library to launch it

import {PythonShell} from 'python-shell';

let pyshell = new PythonShell('my_script.py');  // < --- whatever your script name, in the module folder
 
// the .on handler gets called each time the pythin script writes a message to stdout
pyshell.on('message', function (message) {
  // received a message sent from the Python script (a simple "print" statement)
  console.log(message);
  // send info up to modulename.js
  this.sendSocketNotification("movement", message)
});

@sdetweil This may be a stupid question, but is there any way i can test this on my laptop, without the raspberry pi?

[sdetweil]

@sgarg15 of course. See my comments in .txt file include
https://forum.magicmirror.builders/topic/555/txt-file-include/57

Not the actual node_helper but the code inside. Of course u can install mm on your PC as well

                        // should make this a config variable by adding to module defaults
                       // then would be this.config.counter

                        // setup regex, no i  no g (only once, and case sensitive)

                            // if the name is not zero length (split could have returned for just linefeed
                            if(filename.length >0 && counter >0) {
                               // get the filename prefix
                               var split = splitRegExp.exec(filename);
                               // save name to the output list, as a table entry
                               // remove space after the ->< , the forum hides everything after unless a space
                               // table has a row, 
                               output_list.push("<tr><td>")
                               // with data
                               if(split)
                                  output_list.push(split)
                               else 
                                   output_list.push('name not matched '+ filename)
                               // end of data and row
                               output_list.push("</td></tr>")
                               counter--;
                            } 
                        }  
                    }
                        // insert the table into the wrapper
            console.log( "<table>" + output_list.join('')+ "</table>");

This correct?

@sdetweil Also how do i make it so that the python file is always running?

[sdetweil]

@sgarg15 that was the example of running a little js app on the command line node js_filename

The exact code here doesn’t help you, but the prior code I posted is what u want to try. Altho I don’t know how u will hook it to the sensors on your pc

[sdetweil]

@sgarg15 your python PGM has to loop somehow. I don’t do python

[sgarg15]

@sdetweil so, i have my python script running in the background, and in my nodeHelper.js i would have

import {PythonShell} from 'python-shell';

let pyshell = new PythonShell('Swiping.py');  // < --- whatever your script name, in the module folder
 
// the .on handler gets called each time the pythin script writes a message to stdout
pyshell.on('message', function (message) {
  // received a message sent from the Python script (a simple "print" statement)
  console.log(message);
  // send info up to modulename.js
  this.sendSocketNotification("movement", message)
});

could you explain what movement and message mean in the sendSocketNotification?

If you could help me achieve this, or give me some info that could help me do this i would really appreciate it

[sdetweil]

@ertopps do what?
