help converting code for module...

justjim1220

I need to know how to reconfigure the second line for this work in an MM module…

getTemperature: function() {
	var t = getWmiObject = MSAcpi_ThermalZoneTemperature(Namespace = "root/wmi" | where (Property = instancename) && (EQ = "ACPI\ThermalZone\TZ01_0"));
	currentTempKelvin = t.CurrentTemperature / 10;
	currentTempCelsius = currentTempKelvin - 273.15;
	currentTempFahrenheit = (9/5) * currentTempCelsius + 32;		
	return currentTempCelsius + " C " + currentTempFahrenheit + " F : " + currentTempKelvin + "K";
},

I’m pretty sure rest of the function is ok. But, I could be wrong! :disappointed_face:

justjim1220

latest attempt with this code…

var checkSensorTemps = Temps["\root\wmi:MSAcpi_ThermalZoneTemperature"]["ACPI\ThermalZone"]["THRM_0"];
if (typeof checkSensorTemps !== "undefined") {

	// Core Temps
	var core0Temp = document.createElement("div");
	core0Temp.classList.add("large", "bright", "core0Temp");
	core0Temp.innerHTML = Stats.cpu.threads[i].name + " &nbsp  @  &nbsp " 
		+ ((Temps["\root\wmi:MSAcpi_ThermalZoneTemperature"]["ACPI\ThermalZone"]["THRM_0"].value / 10) -273.15) + " &deg;C "
		+ ((((Temps["\root\wmi:MSAcpi_ThermalZoneTemperature"]["ACPI\ThermalZone"]["THRM_0"].value / 10) -273.15) * 9/5) + 32) + " &deg;F "
		+ (Temps["\root\wmi:MSAcpi_ThermalZoneTemperature"]["ACPI\ThermalZone"]["THRM_0"].value  / 10) + "&deg;K";
	wrapper.appendChild(core0Temp);
}

HELP! LMAO! :face_with_stuck-out_tongue_winking_eye:

@justjim1220 do you have a log of the structure of Temps

@strawberry-3-141

this script ran in powershell …

function Get-Temperature {
    $t = Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace "root/wmi"
    $returntemp = @()

    foreach ($temp in $t.CurrentTemperature)
    {
        $currentTempKelvin = $temp / 10
        $currentTempCelsius = $currentTempKelvin - 273.15
        $currentTempFahrenheit = (9/5) * $currentTempCelsius + 32
        $returntemp += $currentTempCelsius.ToString() + " C : " + $currentTempFahrenheit.ToString() + " F : " + $currentTempKelvin + "K"  
    }
    return $returntemp
}

gives the following output for a single core …

PS C:\WINDOWS\system32> get-temperature
44.05 C : 111.29 F : 317.2K

I’m really only interested in a C and F result, no need for K that I can think of.

@justjim1220 I can’t work with your powershell logs. You’re trying to access the variable Temps in js like your first line. var checkSensorTemps = Temps["\root\wmi:MSAcpi_ThermalZoneTemperature"]["ACPI\ThermalZone"]["THRM_0"];
can you do console.log(Temps) so I can see the structure?

@strawberry-3-141

it throws this error…

@justjim1220 if the variable doesn’t even exist, the rest of the code cannot work at all. first you should make sure that you have your data in the variable and then the second step is displaying it.

It seems like you’re trying to do the ui before you have the data.

I defined Temps. then got this in console…

I had a syntax error in the declaration of Temps.

I’m totally thinking this isn’t going to work.

I will probably need to find a different way,
figured if I could pull it from the SIMBIOS using a simple script, that maybe it could be pulled using a module for MM.

there are some open source apps for Windows that work to get the data, I will just have to study them and see what I can come up with.

Thanks for trying to help.

@justjim1220 if you don’t even have the data in js, you can also execute it in the node helper and parse the response https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback

@strawberry-3-141

What are the chances of being able to do what I had been attempting with this?
https://github.com/moxystudio/node-cross-spawn

And would it be possible to add to a current node_helper being used for linux, or would a separate node_helper or script need made?

@justjim1220

exec(“YOUR-SHELL-COMMAND”, (error, stdout, stderr)=>{
  console.log(stdout)
  // do your job with `stdout`
})

I think you can get the result of any execution of shell script.

@sean

Not sure I follow …

what would be my ‘shell command’?

A Former User

@justjim1220
**
PS C:\WINDOWS\system32> get-temperature
**
I don’t know anything about your intention, but ‘get-temperature’ could be executable in your shell or terminal, it could be the one.

justjim1220

@sean

Yes, that is the command to get the temps from the PC using powershell or command prompt…

BUT, where to use the command in node_helper.js?

OR, where to use the command in the module.js file?

sdetweil

@justjim1220 let’s look at the design of your module.

How often do u need to get the temps?
Is it on a timer, or some other mechanism?

Anyhow, on that cycle, you would issue the ‘run’ of the powershell app in the node_helper.js, and capture it’s output.

Then process the output, remove all the useless data. Then send the raw data to the module.js, who will then format the HTML in the get_dom() function for display

@justjim1220


const exec = require('child_process').exec
var NodeHelper = require("node_helper")

module.exports = NodeHelper.create({
  socketNotificationReceived: function(noti, payload) {
    if (noti == "GIVE_ME_RESULT") {
      setTimeout(()=>{
        exec("C:\WINDOWS\system32\get-temperature", //I don't know WINDOWS system at all. Is it right?
          (err, sto, ste) => {
            if (!err) {
              this.sendSocketNotification("HERE_IS_RESULT", sto)
            } else {
              console.log("Error", err)
            }
          }
        )
      }, 1000)
    }
  }
})

It isn’t tested. But you can catch the idea.
