+    Buttons are designed to trigger an action on a device from Home Assistant, and have an unidirectional flow from 
+    Home Assistant to ESPHome. If you press a button using this action, no button press event will be triggered in Home 
+    Assistant. If you want to trigger an automation in Home Assistant, you should use a
