I’ve been getting the same errors for the last few months at this point. Linux desktop using VirtualBox for HA. I was considering switching to kvm but it looks like this is a cross-platform issue. I’m using a HUSBZB-1. I got a Skyconnect because I thought maybe that was the issue, but it looks like people are having the same problem with those, so I haven’t tried the Skyconnect yet.
I previously had issues with interference, and I never got an error message for that - things just didn’t work. A while back (well before this issue started), I redid my wifi and Zigbee to not be on the same frequencies as much as possible, and for some time things were working perfectly every time. Then this issue started out of the blue.
For me, nothing seems to clear up the issue except time - after waiting a while (a few hours, maybe a day or so), things will start working again. Rebooting the host machine, rebooting the HA VM, etc., none of that seems to make a difference for me.
Edit: I saw someone else was dealing with a busy frequency. Here’s my network scan. I’m using channel 24:
"energy_scan": {
"11": 28.30261646762903,
"12": 28.30261646762903,
"13": 21.09014924761344,
"14": 10.914542804728702,
"15": 17.086630587133605,
"16": 2.2107128772756957,
"17": 4.15070068297423,
"18": 2.84844209578687,
"19": 0.792717332355823,
"20": 0.792717332355823,
"21": 0.9017765778954641,
"22": 0.6123372955913717,
"23": 4.69985354430736,
"24": 0.9017765778954641,
"25": 0.792717332355823,
"26": 17.086630587133605
},
So that doesn’t appear to be my issue.
Edit 2 (really, edit #3, but I didn’t mark the first one): I moved my USB device away from the monitor (it was already on a cable away from the computer, but it was draped behind my monitor) and the issue cleared up immediately. So, maybe that was it, or it might have been just coincidence. Well, we’ll see if it comes back.
Edit 3: Yep it’s still happening.
