MagicMirror² module – Renewable Energy in Europe (initial test: only Germany)

Displays current relevant data for the development of renewable energies in for european countries (inial commit: only Germany is included) in up to four tiles in a flexible grid layout. This module was vibe coded with Anthropic's Claude AI - Sonnet 4.6. Please feel free to adapt it / improve it / make suggestions. Please be aware that this is my first created MagicMirror module - so for sure it does not fullfil the standards in module development (not yet ;-). Your feedback is very welcome!

cd ~/MagicMirror/modules
git clone https://github.com/badubada/MMM-REnergy.git

No npm install required — the module uses only Node.js built-ins.

Minimal config:

{
  module: "MMM-REnergy",
  position: "bottom_bar",
},

Full config with all options:

{
  module: "MMM-REnergy",
  position: "bottom_bar",
  config: {

    // Display language: "de" (German) or "en" (English)
    language: "de",

    // Data refresh interval in milliseconds (default: 15 minutes)
    updateInterval: 15 * 60 * 1000,

    // Number of tiles shown simultaneously: 1 | 2 | 4
    tilesVisible: 4,

    // Grid layout (only relevant when tilesVisible is 4):
    //   "1x4" → all four tiles in a single row
    //   "2x2" → two rows of two tiles
    gridLayout: "1x4",

    // Tile order (remove or reorder as desired)
    tiles:     [
    "wind", 
    "solar", 
    "renewable", 
    "production",
    "windExpansion",
    "solarExpansion",
    "monthlyMix",
    "weeklyMix", 
    "renewableWeekly",
    "batteryLongTerm",
    "renewableEU",
    ],

    // Auto-rotate tiles (useful if tilesVisible < than the number of activated tiles)
    rotation: false,
    rotationInterval: 8000,   // ms between tile changes
    rotationTransition: 600,  // ms fade duration

    // Show sparkline charts in wind / solar / renewable tiles
    showMiniChart: true,

    // Number of days shown in sparkline charts
    chartDays: 30,
  }
},

// activate or deactivate the following tiles:
tiles:  
[
"wind", 
"solar", 
"renewable", 
"production",
//"windExpansion",  //<-- actual data broken!
"solarExpansion",
"monthlyMix",
"weeklyMix", 
"renewableWeekly",
"batteryLongTerm",
"renewableEU",
],

// select visible tiles, options: 1,2,4 (default: 4)
tilesVisible: 4

// select grid layout, options: "1x4", "2x2" <-- only used if tilesVisible > 2
gridLayout: "2x2"

• Data delay: SMARD updates day-resolution data with a 1–2 day lag, so values always reflect yesterday.
• Peak GW: Day-resolution data does not include 15-minute peaks. Values are estimated (wind ×1.4, solar ×2.5 of average).
• 30-day average: Calculated from the last 30 days with complete data across all carriers.

• bug fixes
• include data from all european countries
• ...

Just enter the MMM-REnergy directory and pull the update:

cd ~/MagicMirror/modules/MMM-REnergy
