Issues discovering elero stick

[r00tat]

Hi Istvan,

great work!

I had some troubles finding the correct id of the transmitter stick and I'm not a 100% sure, what went wrong.

TLDR: hass.io's packaging of Home Assistant into a container might break the discovery.

The logs did not show any information about the elero stick, so I did some debugging.

The discovery did not display any Elero sticks, so I wrote a small script (from your sources) to discover the usb stick.

#!env python
import serial
from serial.tools import list_ports
import logging

# Default serial info
DEFAULT_BRAND = 'elero'
DEFAULT_PRODUCT = 'Transmitter Stick'

_LOGGER = logging.getLogger(__name__)
logging.basicConfig(level=logging.INFO)

ports = list_ports.comports()
_LOGGER.info("discovering elero devices")
_LOGGER.info("found %s devices", len(ports))
for cp in ports:
    _LOGGER.info("USB Device: %s %s %s %s", cp.manufacturer, cp.product, cp.device, cp.serial_number)
    if (cp and cp.manufacturer and DEFAULT_BRAND in cp.manufacturer and cp.product and
            DEFAULT_PRODUCT in cp.product):
        _LOGGER.info("Elero - an Elero Transmitter Stick is found on port: '{}'"
                     " with serial number: '{}'.".format(cp.device, cp.serial_number))

It worked in the first place, but now I got:

INFO:__main__:discovering elero devices
INFO:__main__:found 2 devices
INFO:__main__:USB Device: None None /dev/ttyUSB0 None
INFO:__main__:USB Device: None None /dev/ttyAMA0 None

I'm not sure why it worked in the first place but now it didn't.

I'm using Home Assistant with hass.io on a Raspberry Pi4. To execute the code I've used the Cloud9 IDE, running in unprotected mode.

After a restart of Cloud9 I was able to get the the ID of the stick:

INFO:__main__:discovering elero devices
INFO:__main__:found 2 devices
INFO:__main__:USB Device: elero GmbH Transmitter Stick /dev/ttyUSB1 XXXXX
INFO:__main__:Elero - an Elero Transmitter Stick is found on port: '/dev/ttyUSB1' with serial number: 'XXXXX'.
INFO:__main__:USB Device: None None /dev/ttyAMA0 None

So I think the cause of the issue is that Home Assistant is running in a Docker container. I don't know if there is an easy workaround for that issue.

Hi Paul,

Kindly sorry for my late answer. I am very happy about you are using my Elero lib. At first, I have no idea why it happens. My the Home Assistant has been running on a Raspberry Pi3B in a Docker container on USB SSD without any problem for one year. Please give me a time and I will get back soon.

Thanks, Istvan

It seems it's somehow tied to when the stick is connected. If it is connected pre boot it will show up in the logs.

As a recommendation I would say it should be connected before it boots or at least the container is started.

I think we can close this issue.
