Per the docs:
For some devices the /dev/ttyAMA0 device is not detected by udev and is therefore not mapped by Docker. To explicitly set this device for mapping to Home-Assistant, execute the following command using the ssh add-on:
$ curl -d '{"devices": ["ttyAMA0"]}' http://hassio/homeassistant/options
After that, you need to change usb_path to /dev/ttyAMA0 in your configuration.yaml.
zwave:
usb_path: /dev/ttyAMA0
follow those steps and it should start working for you.
I think you’re on the right track - first off, piping your ls command into tail with the -n 1 option is only going to return you one result… so we still don’t know definitively if the Aeotec is recognized on your Pi or not.
Ssh into the Pi and type hassio host hardware. That will return you a list of the hardware attached to the Pi and recognized by Hassio. In the serial section at the top your should see /dev/ttyUSB0 or something similar if the Aeotec is recognized.
Also, the Aeotec is almost certainly going to be recognized as a USB serial device and not AMA, which on the Pi is generally reserved for the hardware UART that hat devices like the Razberry board attach to.
I followed those instructions exactly, changed my config file to reflect AMA0, and…nothing.
I still don’t see anything referring to Z-Wave anywhere in my sidebar or submenus.
Do I need to restart HA? Is there some way for me to force these changes into HA, or do I just have to sit and wait for it to update?
First, thanks for the help.
Entering hassio host hardware returns:
"serial": [
"/dev/ttyAMA0",
"/dev/ttyACM0"
],
"input": [],
"disk": [],
"gpio": [
"gpiochip100",
"gpiochip0"
],
"audio": {
"0": {
"name": "bcm2835 - bcm2835 ALSA",
"type": "ALSA",
"devices": {
"0": "digital audio playback",
"1": "digital audio playback"
}
}
}
}
That’s obviously a little confusing to me because I have both ACM0 and AMA0. I have used AMA0 in my config file, but perhaps it should be changed to ACM0?
Try /dev/ttyACM0
Add this to your configuration.yaml:
zwave:
usb_path: /dev/ttyACM0
Then in the sidebar under Configuration you should have “Z-Wave”
Is there a particular amount of time that has to elapse before it shows up?
I completed this roughly 35 minutes ago (almost immediately after both you and marthocoo posted), and I still see nothing.
I have checked and my config is valid as well, so it’s not that.
Is there a way to force an update to the system to try and get it to show up?
Did you restart homeassistant? Once you do, either the Zwave entry will show up under the configuration menu or you will have an error entry in your log telling us why it isn’t showing up.
@marthocoo - I did not. I didn’t realize that I had to restart it. My apologies.
I’m a bit nervous because the last time I restarted HA, I ended up having to power down the RPI altogether to get it to come back – I lost the ability to access the front end. We’ll see what happens this time.
I will update shortly – thanks again for all of your help. Frustrating to know that this all might have been solved by a restart…
Generally speaking, you always have to restart HA after a configuration.yaml update. There are exceptions but most things require a restart.
OK, so I now have an “Invalid Config” error that comes up.
"The following components and platforms could not be set up:
Please check your config.
So, does this mean that perhaps I should change back to /dev/ttyAMA0 instead of /dev/ttyACM0?
Probably, but the logs (hassio homeassistant logs when your SSHd on) will tell you more. The first 20 lines of the OZW_Log.txt file (in the same directory as configuration.yaml will also be useful)
Yes we need to know what the logs are to diagnose the specific error.
I believe this is the section of the logs that is most relevant. Please note that this is AFTER I changed from ACM0 to AMA0, but it should be noted that I got the exact same error (only with ACM0 instead of AMA0) previously…

Not /dev/tty/ACM0, there’s an extra slash in there that shouldn’t be. It should be: /dev/ttyACM0
Sigh…
deleting my account now, and never coming back…
Thank you, @marthocoo – I think my frustrations were getting the best of me, as I looked over that 100 times. In reality, I just checked back in my Putty logs and I didn’t have the \ in there when I was using ACM0, but I must have added it when I changed it to AMA0.
I now have the Z-Wave menu in my Configuration tab. Now to start actually adding devices…
Thank you all – much, much appreciated.
Typos happen to the best of us.
Enjoy!
I’ve spent a lot of time trying to get Aeotec Z-Wave stick active on the vmdk under virtualbox.

My host is ubuntu 18 and when I run in terminal: ls -ltr /dev/tty*|tail -n 1 I can see, crw-rw---- 1 root dialout 166, 0 Oct 22 17:41 /dev/ttyACM0
when i ssh root@hassio and run the terminal command: ls -ltr /dev/tty*|tail -n 1 I can only see crw-rw-rw- 1 root root 5, 0 Oct 22 10:36 /dev/tty
any help is greatly appreciated - thanks
Hi,
I get the Stick working on VirtualBox. Be sure you are on HassOS 1.11 are higher!
