When in both mode, the target humidity cannot be set from the HA climate entity because it only has a single setpoint for humidity; whereas the Lennox system has a separate targets for humidify and dehumidify. The integration creates number entities to set the target humidity levels:
+  - `number.<system_name>\_<zone_name>\_hum_setpoint`

 ### Supported Data
