CC2531 USB port not accessible

Hardware

Hey everyone,

Im running Hassio and im struggling with integrating an CC2531 USB Stick.
I bought this stick (https://www.amazon.de/gp/product/B07ZZ88BWZ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1) in order to listen to my hue smart button and trigger automations. I used an already installed version, so that I do not need to flash anything. I just put the stick into one of the USB port of the pi.

When I try to set it up I get this Error:

Error setting up entry /dev/ttyUSB2 for zha
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/serial/serialposix.py", line 244, in open
    self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK)
FileNotFoundError: [Errno 2] No such file or directory: '/dev/ttyUSB2'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    hass, self
  File "/usr/src/homeassistant/homeassistant/components/zha/__init__.py", line 103, in async_setup_entry

    raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg))
serial.serialutil.SerialException: [Errno 2] could not open port /dev/ttyUSB2: [Errno 2] No such file or directory: '/dev/ttyUSB2'

I already checked in the GUI of my Hassio and found out, that my HA does not list the dev/ttyUSB2 as a serial. The only once listed are these:

* serial:
  * /dev/serial/by-id/usb-Texas_Instruments_TI_CC2531_USB_CDC___0X00124B0018E21BDA-if00
  * /dev/ttyAMA0
  * /dev/ttyACM0

Do I need to add this port to the hass.io instance? If so, how?
Is my approach wrong and I need to do something with the stick first?

Tanks for your help already in advance.

You can’t use a CC2531 with zha. A CC2531 is for zigbee2mqtt.

3

Oh - that’s good to know. Thanks!

However, can I use zigbee2mqtt for my initial intention? Just listening to the smart buttons and triggering automatons with it?

4

Yes you can.

5

Thanks! When I will try to set it up as a zigbee2mqtt :slight_smile:

I’ve just been trying to do the same and found this page Zigbee Home Automation - Home Assistant which seems to indicate you CAN use the CC2531 USB stick. I’ve tried using the GUI and it doesn’t detect the port even though I use it with Zigbee2MQTT (stopped the docker container to test).

7

You’d quoting an old post of mine. Support for the cc2531 in zha has been added in 0.106, which is 2 weeks old.

8

Did you manage to get this working via ZHA, as I have the same problem?

9

I am having same issue, no serial device path showing. Is there a solution to this?

10

Did anyone found a solution? I have the same problem

Any help is appreciated
