MMM-CaravanPiTemperature - a MagicMirror² Module

This MagicMirror² module is used in the CaravanPi project to display data of a BME280 climate sensor. CaravanPi is a project based on a Raspberry Pi for a smart caravan.

In the CaravanPi project Magic Mirror is used as a display module. The screen is usually not mounted behind a mirror, but can also be used as a TV in the caravan. For the Caravan Pi project there are further modules for Magic Mirror:

MMM-CaravanPiPosition - Module for displaying level information MMM-CaravanPiGasWeight - Module for indicating the filling of a gas bottle via a scale MMM-CaravanPiTemperature - Module for displaying temperature values e.g. in the refrigerator MMM-CaravanPiClimate - Module for displaying climate values

Screendumps

modus: Boxlines

npm install async

Using the module

To use this module, add it to the modules array in the config/config.js file:

modules: [
{
	module: 'MMM-CaravanPiTemperature',
	header: 'Temperaturen Kühlschrank',
	position: 'top_left', // This can be any of the regions.
	config: {
        	valueDir: "/home/pi/CaravanPi/values",
        	updateInterval: 100000, // milliseconds
        	tempUnit: " °C",
        	tempPrecision: 2,
        	showDate: true,
        	sensors: [
            	{
                	name: "Gefrierfach",
                	file: "28-01144febdbaa",
            	},
            	{
                	name: "Getränkefach",
                	file: "28-01144febdbab",
            	},
        	],
        	localeStr: 'de-DE',
        	style: "lines",
    	}
},

]

Configuration options

The following properties can be configured:

Option	Description
valueDir	Optional - The directory in which the values read by the sensors are stored. If not set, the default is: /home/pi/CaravanPi/values
updateInterval	Optional - The update interval in milliseconds. If not set, the default is: 300000 (5 minutes)
tempUnit	Optional - Unit in which the temperature are indicated. Default is °C
tempPrecision	Optional - Decimal places for temperature values. Default is 2
showDate	Optional - Decides whether the date/time at which the values were determined is displayed. Possible values: true or false Default is true
localeStr	Optional - String for country-specific formatting of numbers. Possible values: see Tags for Identifying Languages Default is 'de-DE'
style	Optional - Decides in which style the values are displayed. Possible values: lines, boxes or boxlinesDefault is 'lines'
sensors	Required - Add all your sensors that should appear in the MagicMirror. Each sensor must include the following properties: Option Description name Name that is to be displayed for this sensor. file File name from which the values are to be read
