+title: "HomeAssistant.__init__ requires passing a string to it"
+---
+
+The signature of `HomeAssistant.__init__` has been changed from no arguments to require the configuration directory as a string to be passed to it. Scripts, tests etc. outside of the HomeAssistant core repo which create `HomeAssistant` objects will need to be updated.
+
+The change was introduced in [core PR#98442](https://github.com/home-assistant/core/pull/98442)
+
+If backwards compatibility is important, this is a way to achieve it:
+
+```python
+    try:
+        hass = HomeAssistant()  # pylint: disable=no-value-for-parameter
+    except TypeError:
+        hass = HomeAssistant(config_dir)  # pylint: disable=too-many-function-args
+```
