    Hi everyone,

    I'm trying to switch over to hyperion-ng for that sweet web interface but the LED device LPD8806 is not being detected.

    Everything is working in raspbian with hyperion and I'm just switching SD cards between that and Hyperbian. SPI is activated as well.

    Any things I should try?

    Thanks!

    Thanks for the link. I tried that on a previous install of hyperion-ng and the loopback test passed. Still couldn't get the lights to turn on.

    I'll try it again when I get home for completeness' sake.

    So from the log output:

    [hyperiond LEDDEVICE] (INFO) LedDevice 'lpd8806' found.
    [hyperiond LEDDEVICE] (ERROR) Device disabled, device 'lpd8806' signals error: 'Failed to do initial write'

    Using default settings for port and baud rate. Cut the baud rate in half and it still fails.

    could you please provide a screenshot from the device section
    +
    and retry it with sudo

    Not totally sure if that worked.

    Like manually launch hyperiond as root?

    I tried running hyperiond as root from a terminal and found that it is able to connect and control the strip (at least a bit) as a LPD6803.

    It's changing the colors kinda spasticly as the "warm mood blobs" and not addressing the whole strand but it is being controlled.

    Edit:

    LPD6803 works also while not being root.

    did you installed hyperion-ng by yourself or did you use hyperbian?

    It turns out that pi was already in the spi group

    I just tried out the new Hyperbian and now it's able to connect! The colors are updating and capture is active.

    Curiously, only a portion of LEDs on the bottom are updating. Out of 32 LEDs on the bottom of my screen only 24 are lighting while none on the sides or top light.
