Volvo on Call

[JerryP]

@mz-ber
yes it’s working like above whit out api key

[MZ-BER]

@jerryp Hi Jerry - thank you for checking! I still stuck and I dont know where I’m doing something wrong. I dont want to give up because I know it is still working for you.

The weird thing is that the API works perfect. I can pull all informations from my car via voc dashborad.
Only the module is telling me: No vehicle found

That is my current config:

{
	  module: "MMM-VolvoOnCall",
	  disabled: false,
	  debug: true,
	  position: "top_left",
	  config: {
		scanInterval: 1000 * 60 * 30,
		units: "metric", 
		timestampFormat: "MMM D. HH:mm:ss",
		durationFormat: "HH:mm",
		display: { 
					info: true,
					position: true,
					status: true,
					notice: true,
					trip: true,
					}
				}
			},

It is setup correctly I guess.

I’m wondering where in this node_helper.js is the voc pulled from? I’m not good in JavaScript :-(

const exec = require('child_process').exec
const spawn = require('child_process').spawn
const moment = require("moment")

var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  start: function() {
    this.config = null
    this.carInfo = []
  },

  socketNotificationReceived: function(noti, payload) {
    if (noti == "SCAN") {
      this.scan()
      this.trip()
    }
    if (noti == "INIT") {
      this.config = payload
      this.list()
    }
  },

  list: function() {
    exec("voc list", (e, sdo, sde)=>{
      if (e) {
        console.log("[VOC] ERROR(>list):", e.toString())
      } else {
        this.listResult(sdo)
      }
    })
  },

  listResult: function(output) {
    var re = /^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm
    var matches = null
    var result = []
    while (matches = re.exec(output)) {
      this.carInfo.push({
        id: matches[1],
        type: matches[2],
        vin: matches[3]
      })
    }
    if (this.carInfo.length > 0) {
      this.sendSocketNotification("INITIALIZED", this.carInfo)
    } else {
      console.log("[VOC] ERROR: No vehicle found. Check your account. Module stopped.")
    }

  },


  scan: function() {

      if (e) {

      } else {
        this.scanResult(sdo)
        //this.sendSocketNotification("RESULT", sdo)
      }
    })
  },

      result[idx].push({
        id: matches[1],
        key: key,
        value: value
      })
    }

    if (Object.keys(result).length == 0) {
      console.log("[VOC] ERROR: No information could be retrieved.")

@mz-ber

list: function() {
    exec("voc list", (e, sdo, sde)=>{
      if (e) {
        console.log("[VOC] ERROR(>list):", e.toString())
      } else {
        this.listResult(sdo)
      }
    })
  },

then the good results are parsed in listResult()

[MZ-BER]

@sdetweil Thank you Sam! Can you please tell me what the letters in the bracket mean? (e, sdo, sde)

[MZ-BER]

@mz-ber Oh I guess I understand. If the function is not getting the right details than -> e if everything is okay than -> sdo

[sdetweil]

@mz-ber exec(“voc list”, (e, sdo, sde)=

execs the command “voc list”
and the exec function returns
error (e)
stdout (sdo)
and stderr(sde)

so if no error (e is null)

it sends the command output to the listResults function

[MZ-BER]

@sdetweil Thank you for the explanation. Is the function executing voc list in the terminal? If I’m doing manually voc list I’m getting a result.

Is there a way to see what the script is getting back in detail?

Again, thank you very much!

[sdetweil]

@mz-ber yes executing just like on console

nothing built in to show results.

but you could add a

console.log(sdo)

before the call to listResults()

and see it where u start mm
npm start

it should be the same outout

[MZ-BER]

@sdetweil Alright, I added the console.log before the call listResult() and it is getting the details from my car. I feel sooo close to get this running but I dont know where it is stuck. :anguished_face:

Is maybe the regex search not getting the details viewed?

listResult: function(output) {
    var re = /^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm

[sdetweil]

@mz-ber so the regular expression isn’t finding your text

/^([^ ]+)\s\(([^\)]+)\)\s([^ ]+)$/gm

I use this for building and testing rejects
