-
-```yaml
-# Example configuration.yaml entry
-climate:
-  - platform: radiotherm

-{% configuration %}
-host:
-  description: List of your Radiotherm thermostats. If not provided the thermostats will be auto-detected.
-  required: false
-  type: list
-hold_temp:
-  description: Boolean to control if Home Assistant temperature adjustments hold (`true`) or are temporary (`false`).
-  required: false
-  default: false

-{% endconfiguration %}

-Set `hold_temp: true` if you want temperature settings from Home Assistant to override a thermostat schedule on the thermostat itself. Otherwise Home Assistant will perform temporary temperature changes.

-Multiple thermostats can be assigned by using `host:` if auto-detection is not used.

-```yaml
-climate:
-  platform: radiotherm
-  host:
-    - 192.168.99.137
-    - 192.168.99.202

-Humidity is now available as the `current_humidity` attribute for each `climate.$HOST` entity. This only works for RadioThermostat devices that have a built in humidity sensor.
