Last week I noticed that my Zwave and zigbee devices had become unresponsive. I investigated after a day or two when the problem didn’t fix itself. I’m running a Home Assistant Blue with Zwave JS and ZHA. Looking into it, it appears that home assistant is not recognizing my Nortek USB stick. For instance, when I try to start Zwave JS I get:
Device ‘/dev/ttyUSB0’ does not exist in Z-Wave JS (core_zwave_js).
And when I physically look at the HA Blue, the Nortek stick’s blue power light isn’t on. I’ve done a hard reboot of the system and the USB stick will initially show power (LED on) but after a while it goes off
Hello, I am fairly new here but I have this stick and I’ve had a couple challenges over the last 3 months with different resolutions.
Reboot of host solves some issues like what you’ve described. You’ve done that already so moving on.
I had tried to create some custom zigbee quirks and when I pointed HA at the folder, it borked my zigbee network. I had to use the SSH add on to go into the host level and clear out the folders that were causing it to fail, reboot and it worked fine (I had to do this a few times). This was absolutely user error and there’s steps in the forums on how to do it.
There was a recent HA update that borked the communication of this stick (lost zigbee and zwave). I have seen others report similar problems as of late. All I can say is in those circumstances, there was some sort of an update or restart that resolved my issue. I do see others complaining of seemingly random issues with losing ZHA and ZWA radios after updates but to my knowledge, there’s not yet a clear answer on that.
Go to the supervisor, find the by-id path of the ZWave side of your Nortek stick, then plug that in the port setting section of ZWaveJS instead of /dev/tty/USB0 then restart ZWaveJS.
You’ll probably want to do similar for whatever you’re using for Zigbee with the Zigbee side of the stick - you’ll be able to pick up it’s BY-ID path in the same place at the same time.
I understand what you suggest. But when I look at the hardware list, the Nortek stick does not show up- either as zigbee or Zwave. this follows with the fact that the Nortek stick’s blue led does not come on when inserted into the USB drive.
Previously the stick’s LED would light up when I rebooted the HA Blue, but an attempt today did not yield the same results. And if I put the Nortek stick in my computer, LED lights up. So lack of power isn’t the sticks fault.
Is this pointing to loss of 5V power from the HA Blue?
So I got a powered USB hub, plugged it into the HA blue, and plugged the Nortek stick into the hub. Blue LED- power! However, looking at the hardware lists in Supervisor, the Nortek Zwave and Zigbee protocols are still not showing up on any of the USB ports.
Summary is that my Nortek Zigbee Zwave stick stopped responding in my HA Blue, and the blue power LED on the stick was not on. I bought a powered USB hub to ensure the Nortek stick was getting power, but ZHA and Zwave JS would not start up. Error from Zwave JS:
Device ‘/dev/ttyUSB0’ does not exist in Z-Wave JS (core_zwave_js).
I went to Config/System/Host/Hardware to see if the Zigbee and Zwave had changed id names from ttyUSB0 etc, but the Nortek Zigbee and Zwave “ports” don’t show up as any device path. A couple of USB ports exist but do not contain the Nortek stuff.
I then put the Nortek stick on my laptop and those Silicon lab ports that I’ve been looking for are showing up.
Any suggested next steps? doesn’t look like there is any HA Blue specific support, and I’m assuming software updates would not prevent the USB ports from receiving power.
Figured out the solution- thought I’d share for anyone else out there with the same issue.
The powered USB hub didn’t work on the 4 exposed USB ports. However, the Home Assistant Blue has a microUSB port on the board that is covered by the housing. I took off the housing and plugged in an OTG (on the go) cable to the microUSB, and the powered Hub to the OTG cable, and then the Zwave/Zigbee stick to that.
