+- Updated the Homeasistant Discovery topics (#3332)
+    - `raw` has now set the `State Class` to `measurement`. Before the `State Class` was always set to `""`. 
+    - `value` has now only set the `State Class` to `total_increasing` if `Allow Negative Rates` is NOT set. Else it uses `measurement` as it could go down. Before it was always set to `total_increasing`.
+    - The `rate_per_time_unit` topic of an **Energy** meter needs a `Device Class`=`power`. For `gas` and `water` it should be `volume_flow_rate`. Before the `Device Class` was always set to `""`.
