RuntimeError: hass_agent calls device_registry.async_update_device from a thread other than the event loop

[baznab]

Description (English):

I get the following error multiple times in my Home Assistant logs (33 occurrences in my case). It seems related to thread safety in the device registry update.

Environment:

• Home Assistant : 2025.8.3
• HASS.Agent Integration: 2022.11.9
• HASS.Agent for Windows: 2022.14.0
• Host OS: Home Assistant OS (Raspberry Pi 5)

Error log:

RuntimeError: Detected that custom integration 'hass_agent' calls device_registry.async_update_device from a thread other than the event loop, which may cause Home Assistant to crash or data to corrupt.
For more information, see https://developers.home-assistant.io/docs/asyncio_thread_safety/#device_registryasync_update_device
at custom_components/hass_agent/__init__.py, line 29: device_registry.async_get_or_create(

Steps to reproduce:

• Start HA with HASS.Agent integration enabled.
• Wait for startup.
• Error appears repeatedly in logs.

Expected behavior:

The integration should update the device registry without triggering async/thread safety errors.

Résumé en français :

Lorsque j’utilise l’intégration HASS.Agent, j’ai une erreur répétée dans les journaux de Home Assistant (33 occurrences lors du dernier démarrage).
Le message indique que l’intégration appelle device_registry.async_update_device depuis un thread non compatible avec la boucle événementielle, ce qui pourrait théoriquement causer un crash ou une corruption de données.

Mon environnement :

• Home Assistant Core : 2025.8.3
• Intégration HASS.Agent : 2022.11.9
• Application Windows HASS.Agent : 2022.14.0
• OS : Home Assistant OS (Raspberry Pi 5)

Thanks a lot for your work on this integration! HASS.Agent is really useful to control and monitor Windows PCs from Home Assistant.

Putting my +1 in here, I have the samme issues and they have intensified with latest updates. In addition to the above warning from System log, I also get this below message equal amount of times, now 180 times in about 2 hours.
