Hyperion cant connect to a device symlink-ed Adalight

1. offizieller Beitrag

    With multiple USB devices i created a symlink through udev to make sure after booting or whatever may happen my adalight (el cheapo Arduino Nano) wil always be reachable on "ttyUSBhyperion"


    Code: /etc/udev/rules.d/99-usb-serial.rules
    SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", SYMLINK+="ttyUSBhyperion"

    and the command readlink -f /dev/ttyUSBhyperion nicely returns /dev/ttyUSB1 (in this case the correct device


    When i configure the adalight with outputpath /dev/ttyUSB1 it functions great... but when i configure it with /dev/ttyUSBhyperion the log returns the following error

    2021-05-16T14:18:41.971Z [hyperiond LEDDEVICE] (ERROR) Device disabled, device 'adalight' signals error: 'Invalid serial device name: [ttyUSBhyperion]!'


    Hyperion 1.0.0 had no issues with this symlink like this but since i updated to "NG"/2.x i need to use the direct /dev/ttyUSBX

    Is there something im missing here or is this a bug/feature of Hyperion NG?


    OS: Debian GNU/Linux bullseye

    Hyperionversion: 2.0.0-alpha.9

    LED Device: Arduino Nano adalight

    geephile Is it ok to display the udev and "real" devices next to each other in the device selection drop-down?
    Or is there a special need to mark the udev ones explicitly as such? Below the udev device is the selected one.

    Edit: You can test udev-Support via PR1246

    Lord-Grey Sorry for the delay in answering


    Trying to test your solution gave me the error as described in post:

    Just removed it and installed again, as couldn't remember the message I got: -

    So following that thread (and adding info if needed) aswell


    As for your question, nice to have a dropdown but for me personally its enough to have a simple input box.

    The new version will have the dropdown anyway. My question was more in the direction, if the udev/symlink Devices need to be marked as such.

    I am happy to leave it this way and the udev User anyway knows what to select….
