 # Changelog
 
+## 0.7.7 - 2026-06-15
+- WebSocket-State-Changes lesen jetzt das echte Home-Assistant-Eventformat
+  (`event.data.entity_id`), damit Kontextwechsel wie Türsensoren sofort
+  Vorhersagen und Schaltungen auslösen statt erst beim nächsten Statusabruf
+
 ## 0.7.6 - 2026-06-14
 - Kontextvorschläge blenden zusätzlich Batterie-, Status-, Node-, Last-Seen-
   und Basic-Entities aus, sofern sie nicht bewusst manuell ausgewählt wurden
