====== Homeassistant ======

Da ich Homeassistant primär rund um die Solarerzeugung und Speicherung nutze, habe ich diese Seite mal unter Solar gehangen, auch wenn ich andere Dinge damit erfasse.

===== Hoymiles Inverter auslesen und darstellen =====

Um Hoymiles und ähnliche Inverter per Funk auslesen zu können, gibt es zwei Open Source Projekte: AhoyDTU und openDTU.

Ich habe mich für AhoyDTU entschieden, da die initiale Inbetriebnahme total easy ist und ich die Oberfläche "schöner" finde.
