+title: "Climate entity now validates temperature provided in action calls"
+---
+
+As of Home Assistant Core 2024.8, we have implemented validation for the temperature action call provided by the `ClimateEntity`.
+
+Integrations no longer need to check this within their own set temperature methods (`async_set_temperature`/`set_temperature`).
+
+However, it's important that integrations specify the `min_temp` and `max_temp` properties correctly, or the user might not be able to set their correct temperature if validation fails.
+Likewise, integrations that handle devices which can operate on both `Celsius` and `Fahrenheit` need to convert their respective `min_temp` and `max_temp` values accordingly.
+
+
+### Example
+
+Converts a device's native min/max value into the temperature_unit specified by the integration.
+
+```python
+
+class MyClimateEntity(ClimateEntity):
+    """Implementation of my climate entity."""
+
+    @property
+    def min_temp(self) -> float:
+        """Return the minimum temperature."""
+        return TemperatureConverter.convert(
+                self.device.min_temp, UnitOfTemperature.CELSIUS, self.temperature_unit
+            )
+
+    @property
+    def max_temp(self) -> float:
+        """Return the maximum temperature."""
+        return TemperatureConverter.convert(
+                self.device.max_temp, UnitOfTemperature.CELSIUS, self.temperature_unit
+            )
+
+```
