by Alex Johnson 48 views

Experiencing issues with the historical analysis failing to run in Home Assistant (HASS) 2025.12.b0 can be frustrating. This article dives into a specific case reported by a user, providing a detailed overview of the problem, system information, and potential troubleshooting steps. We'll break down the error messages, explore the system environment, and guide you through the process of resolving this issue.

Understanding the Issue: A Deep Dive

The user reported an issue with the Area-Occupancy-Detection integration after upgrading to the beta version of Home Assistant 2025.12.b0. The core problem lies in the failure to run historical analysis, as indicated by the error message:

Failed to run historical analysis: Caught blocking call to sleep with args (0.05,) inside the event loop by custom integration 'area_occupancy' at custom_components/area_occupancy/db.py, line 222: FileLock(self._lock_path, timeout=timeout),. (offender: /usr/local/lib/python3.13/site-packages/filelock/_api.py, line 344: time.sleep(poll_interval)), please create a bug report at https://github.com/Hankanman/Area-Occupancy-Detection/issues For developers, please see https://developers.home-assistant.io/docs/asyncio_blocking_operations/#sleep

This error message is crucial for pinpointing the root cause. Let's dissect it:

  • Failed to run historical analysis: This is the overarching symptom. The Area Occupancy Detection integration relies on historical data for its functionality, and the failure to analyze this data hinders its operation.
  • Caught blocking call to sleep with args (0.05,) inside the event loop: This is the heart of the problem. Home Assistant's core architecture is built around an asynchronous event loop. This means that tasks should be executed in a non-blocking manner to prevent the entire system from freezing. The error indicates that a time.sleep() call, which is a blocking operation, was made within the event loop. This blocks the main thread, preventing other tasks from running and potentially leading to instability.
  • by custom integration 'area_occupancy' at custom_components/area_occupancy/db.py, line 222: This tells us that the blocking call originates from the Area Occupancy Detection custom integration, specifically within the db.py file at line 222. This is where the integration interacts with the database.
  • (offender: /usr/local/lib/python3.13/site-packages/filelock/_api.py, line 344: time.sleep(poll_interval)): This further narrows down the issue to the filelock library, which is used to prevent concurrent access to files. The time.sleep() call is being made within the filelock library's implementation.
  • please create a bug report at https://github.com/Hankanman/Area-Occupancy-Detection/issues For developers, please see https://developers.home-assistant.io/docs/asyncio_blocking_operations/#sleep: This is a standard error message in Home Assistant, directing users to report the issue to the integration's developers and providing resources for developers to understand and fix the problem.

The error essentially means that the Area Occupancy Detection integration is using a blocking operation (time.sleep()) within the asynchronous event loop, which is a big no-no in asynchronous programming. This can cause performance issues and even crashes.

Examining the System Environment: The Devil is in the Details

To effectively troubleshoot, understanding the system environment is paramount. The user provided a detailed system health report, which gives us valuable insights:

Core System Information

  • version: core-2025.12.0b0 (This confirms that the user is running the beta version where the issue surfaced.)
  • installation_type: Home Assistant OS (This indicates a full-fledged Home Assistant OS installation, which simplifies some aspects of troubleshooting but also introduces OS-level considerations.)
  • python_version: 3.13.9 (This is a relatively new Python version, and compatibility issues with older integrations are possible.)
  • os_name: Linux
  • os_version: 6.12.43-haos
  • arch: x86_64

Home Assistant Community Store (HACS)

The user utilizes HACS, which is a popular way to install custom integrations. This is relevant because the Area Occupancy Detection integration is likely installed through HACS. The report shows:

  • Installed Version: 2.0.5
  • Available Repositories: 2466
  • Downloaded Repositories: 27

This information helps in verifying the specific version of the integration and checking for potential updates.

Home Assistant Cloud

This section details the user's Home Assistant Cloud (Nabu Casa) subscription and connectivity. While not directly related to the error, it confirms a functioning cloud connection, which can be helpful for remote access and troubleshooting.

Home Assistant Supervisor

The Supervisor manages the core Home Assistant system, including updates and add-ons. Key details include:

  • host_os: Home Assistant OS 16.2
  • supervisor_version: supervisor-2025.11.6
  • installed_addons: This lists various add-ons, such as Matter Server, Mosquitto broker, Samba share, and importantly, MariaDB (2.7.2). This is critical because the Recorder (database) uses MariaDB.

Recorder

This section provides information about the database used for recording historical data, which is directly related to the reported issue:

  • oldest_recorder_run: November 22, 2025 at 12:23 AM
  • current_recorder_run: November 29, 2025 at 12:01 PM
  • estimated_db_size: 1138.27 MiB
  • database_engine: mysql
  • database_version: 10.11.6

This confirms that the user is using MySQL (MariaDB) as the database engine, and the database size is significant (over 1GB), suggesting a substantial amount of historical data. The fact that the oldest recorder run is a week prior to the issue surfacing is also relevant.

Potential Causes and Troubleshooting Steps

Based on the error message and the system information, here are several potential causes and corresponding troubleshooting steps:

1. Blocking Call in filelock

  • Root Cause: The core issue is the blocking time.sleep() call within the filelock library, triggered by the Area Occupancy Detection integration. This is likely a bug in the integration's code.
  • Troubleshooting Steps:
    • Report the issue: The error message explicitly asks to create a bug report on the integration's GitHub repository (https://github.com/Hankanman/Area-Occupancy-Detection/issues). This is the most crucial step.
    • Check for updates: Look for updates to the Area Occupancy Detection integration in HACS. The developer might have already released a fix.
    • Downgrade the integration: If a recent update introduced the issue, consider downgrading to a previous version of the integration. This can be done through HACS.
    • Disable the integration: As a temporary workaround, disable the Area Occupancy Detection integration to prevent the errors and potential system instability. This will, of course, disable the integration's functionality.

2. Database Locking Issues

  • Root Cause: The filelock library is used to prevent concurrent access to the database. The blocking call might indicate a problem with database locking, where the integration is waiting for a lock to be released, causing the time.sleep() call.
  • Troubleshooting Steps:
    • Check database performance: Monitor the performance of the MariaDB database. High CPU usage, slow queries, or database errors could indicate locking issues. You can use tools like phpMyAdmin or the MariaDB command-line client to investigate.
    • Optimize database queries: If slow queries are identified, try optimizing them. This might involve adding indexes or rewriting the queries.
    • Increase database resources: If the database server is under-resourced, consider increasing the allocated memory or CPU.
    • Review recorder settings: Check the recorder settings in your configuration.yaml file. Reducing the purge_keep_days setting (the number of days of history to keep) can reduce the database size and potentially improve performance.

3. Python 3.13 Compatibility

  • Root Cause: The user is running Python 3.13, which is a relatively new version. It's possible that the Area Occupancy Detection integration has compatibility issues with this Python version.
  • Troubleshooting Steps:
    • Check integration compatibility: Review the integration's documentation or GitHub repository for information on Python 3.13 compatibility.
    • Wait for updates: If there are compatibility issues, the integration developer will likely release an update to address them.

4. Home Assistant Beta Issues

  • Root Cause: The issue surfaced in the beta version of Home Assistant. Beta versions are inherently less stable than stable releases, and bugs are expected.
  • Troubleshooting Steps:
    • Report the issue: In addition to reporting the issue to the integration developer, also report it to the Home Assistant core team through the Home Assistant GitHub repository or community forums.
    • Consider downgrading: If the issue is critical, consider downgrading to the stable version of Home Assistant.

Specific Steps for this User

Given the information provided, here are the recommended steps for the user:

  1. Report the issue: Create a detailed bug report on the Area Occupancy Detection integration's GitHub repository, including the error message, system information, and steps to reproduce the issue.
