+title: Device tracker TrackerEntity location accuracy attribute type change
+---
+
+The type of `location_accuracy` attribute (short hand `_attr_location_accuracy`) of the `TrackerEntity` class of the `device_tracker` entity component has been changed from `int` to `float`.
+
+Type conversions in case the source value is a `float` are no longer needed.
+
+### Example
+
+```python
+class ExampleTrackerEntity(TrackerEntity):
+    """Test tracker entity."""
+
+    _attr_location_accuracy: float = 2.5
+
+    @cached_property
+    def location_accuracy(self) -> float:
+        """Return the location accuracy of the device.
+
+        Value in meters.
+        """
+        return self._attr_location_accuracy
+```
