How to use the MH-Z19 Co2 Sensor on Hass.io?

Hi!
I try to install the MH-Z19 sensor to my hass.io on a Raspberry Pi3b+.
I conected the sensor to the pi by this guide.
After that, I edit the config.txt in the boot directory and add

enable_uart=1

by this guide.

Then I reboot HA but this error appears:

(SyncWorker_19) [homeassistant.components.mhz19.sensor] Could not open serial connection to /dev/tty.S0 ([Errno 2] could not open port /dev/tty.S0: [Errno 2] No such file or directory: '/dev/tty.S0')

I’m on HA Version 0.93.2

Can someone help me?

Thanks, Marius

Check /dev to see what serial ports you have when your device is connected:

ls -la /dev/tty*

also make sure your user is a member of the dialout group:

pi@haven:~ $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi

That would be a very strange linux device node. It would usually be /dev/ttyUSB0 or similar. But dmesg should tell you. Try

dmesg|grep -C5 tty

This is this the result:

core-ssh:~# ls -la /dev/tty*
crw-rw-rw-    1 root     root        5,   0 May 28 20:41 /dev/tty
crw-rw----    1 root     audio     204,  64 May 28 20:41 /dev/ttyAMA0
crw-rw----    1 root     audio       4,  64 May 28 20:41 /dev/ttyS0
core-ssh:~# groups
root bin daemon sys adm disk wheel floppy dialout tape video

This is the result:

But I don’t know what it is…

There are only two tty devices that it can possibly be. The same was shown in the ls /dev/tty* command.

I changed
/dev/tty.S0
to
/dev/ttyS0

and it works! Thank you for your help!

@Marius82 I am having a similar problem with my first HA install on a Virtual box. How do you fix the tty=(none). I am not an expert on the Linux side and this is an install of the VMDK file from the HA website.
