Thanks for any and all help. None of this makes sense as to what the problem actually is. I am using RPi 4 and M.2, not sure if that makes a difference.

I don’t get the error messages, and you might be way more skilled than I am, but are you using an extension cord to your Conbee stick?

There is an issue with interference caused by USB 3 ports, and I believe that RPi4 have those.

You might know that, but if not, you (and others that might stumble in here) could try using an extension cable to move the Conbee stick further away from the RPi.

You’re absolutely right. I got a 4’ 4-way extension and suddenly it works. Not sure if it was that or the core update but I’m fixed :man_shrugging:t4:

I’m super glad that I were able to help, first time on this forum that I got to give back!

Ok this was such a simple fix.

My ZHA refused to come back online after a restart on Friday, tried everything, and even have a new stick ordered.

Gave this a try with a 25cm USB extension cable and it started back online immediately!

Thanks
