Great it works !!!!!!

My circuit board looks completely different. Could someone please take a look and see if I need to solder anything or if I can use it as is? Thank you very much. pclin thank you for your link for the rainbow signal problem.

I've ordered the grabber myself and will test it out. Thank you very much.

I currently have this grabber, and when I turn off my TV, the rainbow signal remains. Do you perhaps have an optimal setting for how I can get rid of it when my TV is switched off?

Could it be that my HDMI switch isn't getting enough power? I get power from the TV's USB port. Everything worked fine six months ago.

Unfortunately, it didn't work for me. Sometimes it runs for 20 minutes, sometimes for an hour, and then the lights go out again. I have to turn Hyperion off and on again for the LEDs to light up again. Do you have instructions on how you did this via Putty SSH to install the correct drivers?

I have the same problem, but only when the RPI is unplugged and restarted. Unfortunately, I haven't found a solution yet.

Hello,

My LEDs (WS281x) only light up for 5 minutes, and then I have to deactivate and reactivate them via the web interface. Then it runs for about 5 minutes and the lights go out again. Has anyone found a solution yet?

I have the same problem with the Raspberry Zero WH. It only works when I deactivate and activate it.

Do you already have a solution?

Hello everyone,

I have a problem with my LEDs and the Raspberry Pi Zero that I would like to discuss here. It's about the connection between the Raspberry Pi Zero and my USB grabber.

The problem occurs every time I restart the Raspberry Pi Zero. The connection to the USB grabber seems to be lost. The USB grabber is displayed in the Hyperion web interface, but the LEDs remain dark. The only thing that helps is to deactivate the grabber via the web interface and then activate it again. Only then will the LEDs work again, until the next restart of the Raspberry Pi.

Here are some details about my configuration:

Raspberry Pi Zero with Raspbian OS

USB grabber (manufacturer and model on request)

Hyperion version (on request)

LED setup (number and type of LEDs on request)

Have any of you had a similar problem before or have an idea how I could fix it? Is there a way to automatically reinitialize or activate the USB grabber when starting the Raspberry Pi Zero so that I don't have to do this manual readjustment every time?

Thank you in advance for your help!
