MeshCore crashed since yesterday

[Rempert]

Since yesterday, I noticed that no events were being triggered in HA. After investigating, I found an error message in the log:

"Error retrieving messages: {'reason': 'no_event_received'}"

which caused a crash. A bit more detail:

2026-01-23 16:36:34.754 ERROR (MainThread) [custom_components.meshcore.coordinator] Error retrieving messages: {'reason': 'no_event_received'}
2026-01-23 16:36:54.754 ERROR (MainThread) [custom_components.meshcore] Failed to get self telemetry: {'reason': 'no_event_received'}
2026-01-23 16:36:59.757 ERROR (MainThread) [custom_components.meshcore.coordinator] Error retrieving messages: {'reason': 'no_event_received'}....

A restart fixes the problem for a few minutes before it starts again. Has anyone else experienced this?

To this end, the HA has been working well with Meshcore for weeks. A traceback indicates the following:

Traceback (most recent call last):
File "/usr/local/lib/python3.13/logging/handlers.py", line 1509, in emit
self.enqueue(self.prepare(record))

File "/usr/local/lib/python3.13/logging/handlers.py", line 1491, in prepare
msg = self.format(record)
File "/usr/local/lib/python3.13/logging/__init__.py", line 999, in format
return fmt.format(record)
~~~~~~~~~~^^^^^^^^

record.message = record.getMessage()
~~~~~~~~~~~~~~~~~~^^
File "/usr/local/lib/python3.13/logging/__init__.py", line 400, in getMessage
msg = msg % self.args
~~~~^~~~~~~~~~~

Could it be that a corrupt string is being received?

Thanks!

I have this issue with the same errors, usb connection on raspberry pi 4. Seems rebooting HA can temporary fix this issue

It's hard to say for certain, that is the general behavior you will see when a connection is lost. The trace given doesn't contain any integration code
