The state-file will be created after the first homekit connection. It sounds like this process was never fulfilled.

May I ask if you are experiencing this issue under the Windows operating system? I have also encountered this issue. I tried to add the following code in line 646 of "pyhap/accessory_driver. py" to solve this problem。

with open(self.persist_file, "w", encoding="utf8") as file_handle:
    self.encoder.persist(file_handle, self.state)

On Windows os.chmod fails if the file doesn't exist; it's failing trying to make the current persistence file writable by the user, in preparation for swapping in the temporary file just written.
