Nabu_Casa_SkyConnect "No Such file or directory Directory" - Where should I start looking?

Hardware

My Zigbee network has been stable for a coupe of years with no changes, additions or modifications, but all of a sudden I’m getting failures.

I loose communication with all of my Zigbee devices, and when I look at the Zigbee integration I see the following error message:

SkyConnect v1.0, s/n: 5433d0fb1b97ed119083c998a7669f5d - Nabu Casa

Failed setup, will retry: [Errno 2] No such file or directory: ‘/dev/serial/by-id/usb-Nabu_Casa_SkyConnect_v1.0_5433d0fb1b97ed119083c998a7669f5d-if00-port0’

Reloading the automation does not resolve the issue, but rebooting HA does. Sometimes this is effective for a couple of days, sometimes a couple of hours, but it eventually drops out again.

I’m using ZHA, some of my devices (44) don’t play well with MQTT.

There are no entries in the Home Assistant Core log for the time period.
There are no entries in the Home Assistant Supervisor log for the time period.
There are no entries in the Home Assistant Host log for the time period.

I’m using the latest stable build.

How old is that stick?
If it was bought in a certain age range, some had a manufacturing defect and were replaced.
You should search that here and see if this stick is in the affected group.

Do you have a link, or more information on what I would need to know to check my sky connect against he defective batch?

It’s the blue dongle, purchased in late 2023, and has been running flawlessly up until last week.

Put this into a search engine:

site:www.home-assistant.io SkyConnect replacement

Something is wrong, it’s only showing this page.

6

A search engine like google or duckduckgo

According to this, I don’t have one of the effected units.

I think that this started after one for the recent updates, but I’m not certain as there were a string of them close together.
