and the Tradfri integration has become horribly unreliable because connection is lost all the time. there are a great deal of partnering wanring/errors, this mention aiocoap too:

there are many more mentioning the tinytdls, and of course issues have been raised in Home Assistant Tradfri integration

https://github.com/home-assistant/core/issues/105004 https://github.com/home-assistant/core/issues/85254#issuecomment-1838614615 and more.

Hope you can have some pointers what to do, where to look. Instruct me to debug this please. thanks

getting worse and worse

Are there any clues as to what else changed when this became more frequent? Were more clients added to tradfri, or components updated whose changelogs could contain hints?

Mariusthvdb commented 5 months ago

not really no, not that I can imagine.

maybe only some beter logging in the scripts/automations section, so making things more obvious?

as a matter of fact, Ive even taken out some of the entities to go to the new Dirigera, or ZHA.

Ive tried to describe things as accurately as possible, and add new info if and when applicable. It's all we can do as users, the core dev team is the only team that can further investigate having all required knowledge.
