A Temperature Monitor using Nodejs and MQTT

A PC temperature monitor that sends the reads using MQTT
Currently only supports CPU and Nvidia graphic temperatures

I'm using this to send the temperatures to the Home Assistant broker

Prerequisites

1 - NodeJS
2 - Nvidia Graphic Drivers

In Windows you probably have to add this to your PATH variable

C:\Program Files\NVIDIA Corporation\NVSMI

An example of configuration.yaml for Home Assistant

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/0'
    name: 'CPU - Thread 0'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/1'
    name: 'CPU - Thread 1'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/2'
    name: 'CPU - Thread 2'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/3'
    name: 'CPU - Thread 3'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/4'
    name: 'CPU - Thread 4'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/cpu/5'
    name: 'CPU - Thread 5'
    unit_of_measurement: '  C'

  - platform: mqtt
    state_topic: 'computer/temperatures/graphic-card/1'
    name: 'Graphic Card'
    unit_of_measurement: '  C'

With some tweaks the result will be something like this :)

Installation

Change the config.json file for your broker settings

$ npm install

Usage

$ npm start

or

$ node index.js
