My first post in this forum and my first module:
MMM-HoymilesPVMonitor displays live PV power and energy data from a Hoymiles inverter and DTU:

https://github.com/CuddlyCow/MMM-HoymilesPVMonitor

The module queries the DTU via the local network at regular intervals and visualizes the current power, daily energy, and total energy values on your MagicMirror.

Features

• Fetches real-time PV data from your Hoymiles DTU
• Displays:
  – Current power (W)
  – Daily energy (kWh)
  – Total energy (MWh)
• Visual donut chart created with Chart.js
• Automatically updates at configurable intervals
• Keeps showing the last known energy values at night when the DTU stops responding
• Stores all daily values with timestamps in a local history file

Sorry, first time publishing on github… The repository is set to “public” but I can only reach it when logged in to my account. When logged out, github throws a 404 error… Perhaps some automated review process? Account and repo to github are new (<24h).
