Volvo on Call

[MZ-BER]

@jerryp Okay, do I need an api key from google maps?

[JerryP]

@mz-ber
yes i’f you use the map function. I have add the api and it’s working fine

[MZ-BER]

@jerryp is it working for you without the map function? I’m actually not interested in it.

[JerryP]

@mz-ber
Yes but i have put the api key in the config. I dont have try it whitout the key

[MZ-BER]

@jerryp Would you do me a favor and test it without the key or a wrong key? Just wondering if that is the issue

[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")

      this.config = payload
      this.list()
    }
  },

  list: function() {
    exec("voc list", (e, sdo, sde)=>{

        console.log("[VOC] ERROR(>list):", e.toString())

@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
