+### System-Level Entities
+
+The integration creates a "RDZ HMI System" device with the following entities:
+
+**Sensors:**
+- **Outside Temperature**: Current outdoor temperature from the system
+- **Delivery Water Temperature 1-8**: Actual water temperatures being delivered by each system
+- **Calculated Water Temperature 1-8**: Target water temperatures calculated by each system
+
+**Binary Sensors:**
+- **Pump 1-8 Active**: Shows whether each circulation pump is currently running
+
+**Switches:**
+- **Season Switch**: Controls global heating/cooling mode
+- **System 1-8**: Enable/disable each heating/cooling system
+
+**Number Entities:**
+- **Day, Month, Year, Hour, Minute**: Configure the RDZ system's internal clock
