Changes for 1.3.2.8

## Added

- `import_entity` and `export_entity` on `grid` can be set instead of single grid power entity. (YAML only)
- `charge_entity` and `discharge_entity` on `battery` can be set instead of a single battery power entity (YAML only)

## Changed

- Added a time-based smoothing to the flow animations to try and resolve glitches from fast updating power entities.

+**Separate Entities for Grid or Battery:**
+
+If you don't have a single entity for grid or battery power, you can instead use separate entities for both. This is not part of the configuration UI, it can only be added as YAML manually to the card. 
+
+For Grid:
+
+| Name                | Setting slug            | What it does                                                                    |
+| ------------------- | ----------------------- | ------------------------------------------------------------------------------- |
+| Import Entity              | `import_entity`                | Sensor defining the import power from the grid.                                               |
+| Export Entity              | `export_entity`                | Sensor defining the export power from the grid.                                               |
+
+For Battery (can be provided for each battery):
+
+| Name                | Setting slug            | What it does                                                                    |
+| ------------------- | ----------------------- | ------------------------------------------------------------------------------- |
+| Charge Entity              | `charge_entity`                | Sensor defining the import power from the grid.                                               |
+| Discharge Entity              | `discharge_entity`                | Sensor defining the export power from the grid.    
+
+Example:
+
+```yaml
+type: custom:compact-power-card
+entities:
+  pv:
+    entity: sensor.givtcp_pv_power
+  battery:
+    - charge_entity: sensor.givtcp_charge_power
+      discharge_entity: sensor.givtcp_discharge_power
+    - charge_entity: sensor.givtcp_charge_power_battery2
+      discharge_entity: sensor.givtcp_discharge_power_battery2      
+  grid:
+    import_entity: sensor.givtcp_import_power
+    export_entity: sensor.givtcp_export_power
+    decimal_places: 1
+    threshold: 0

 **Battery only:**
 
 | Name                | Setting slug            | What it does                                                                    |
