Hello
I’ve installed home assistant locally on the rpi raspbian and then add
zwave:
usb_path: /dev/ttyS0
to configuration.yaml

( My zwave controller use port ttyS0.)

I configure disable a login shell to be accessible over serial and configure the serial port hardware to be enabled.

But when I went to Z-Wave Control Panel in Home assistant and follwer include instruction.

It show the error ,and can’t add device .

It can’t open the controller. What does ls -al /dev/ttyS0 show?

Also, it’s not normal for the controller to show as ttyS*, normally it’s ttyACM* or ttyAMA*. What Z-Wave stick are you using?

Have you added the Home Assistant user to the dialout group?

It show
crw-rw---- 1 root dialout 4, 64 May 31 14:57 /dev/ttyS0

after I typed ls -al /dev/ttyS0.

I used Matrix Creator as ZWAVE controller.It use SIGMA designs ZM5202 and It used port ttyS0 to connect ZWAVE but not ttyACM0.
I can add ZWAVE device directely from this ZWAVE controller but can’t addnode from Home assistant

There is also an erreur message after I run again
$sudo -u homeassistant -H /srv/homeassistant/bin/hass

I’ve added homeassistant as user to the dialout group.

sudo useradd -rm homeassistant -G dialout

I’m pretty sure the problem is that your IoT device isn’t a Z-Wave controller USB stick. I’d ask on the OpenZWave mailing list to see if they can support these.
