okay, use only 1 channel MAIN HDMI out on AVR. (deselect output 2 if available)
connect the splitter to that channel, set on Auto not Copy mode.
then main TV on output channel 2
then the loop grabber hdmi cable on channel 1.
usb to Raspi 3b.
and put the log here >> debuglog with expertsettings level
How can i manage to light up the leds alone instead of in a segment of three?
you cant, they are: 3 in group connected per each IC together. Hyperion.NG steers only the IC's not the leds individually.
I had a feeling this was the problem.
For this to achieve you need a ledstrip like HD107S, really nice 5 volts individually programmable leds 
normally with 5v ledstrips each IC is connected to one led. The IC can be integrated IN the led or next to the led.
diagram of SK6812
i get it, its maybe because of 12v system ledstrip.
each section lights 3 leds instead of lighting individually
so you have to do the ledcount divided by 3 per side.
i think this wil solve it.
let me know if this helped.
i dont know where you want to go with this setup, but yes you can blacklist every other led in Hyperion.NG
led is physically there but wont lid.
so 1/3/5/7/9 will and 2/4/6/8 etc won't
get it?
in this way you have the "layout " of a 30l/mtr strip.
i have Raspi 3b with 1024 RAM and runs Hyperion.NG 2.016 build with settings on hdmi usb grabber; 720p 25FPS and size decimation on 3.
so anything higher as Raspi 3b is fine You dont need to grab 4k to have nice ledlights, dont be fooled
at least Rasp3, Raspi4 is even better
Or would you say soldering CI/DI directly is the most likely fix here?
try that first i would do.
Probably you touch something when going behind the tv, loose connection/wire or joints that weren't perfect but just barely okay.
If using Wago's >> use only one port and twist all wires in that port.
I checked all wiring with a multimeter and confirmed continuity everywhere
There shoulnd't be any continuity, probably thats what you meant >> between DI/CI NO continuity between GND/5volts NO continuity
should be in screen> OL and no beep audible
Could it also be a defect in the LED strip or even the Pi itself?
thats also possible, but if it was me i start troubleshooting with Debug-log > wiring/joints/contacts > defectively hardwares
Could it be that this additional connection is already enough to disturb the DI/CI signals and cause the LEDs to stay white
yes that's possible, if the connection on GPIO has to be without resistance.
When using jumpercables that aren't tight around GPIO you get resistance because the contact is minimum, thus data signals can not go freely where they want to the strip. Thatswhy i always solder on my GPIO's
what does the Debug log says now?
Don't forget to run Hyperion in expertmode to be able to see the log
did you change the hardware LEd count
did you measure on ledstrips contactpoints/solderpoints between DI and CI if there isn't any continuity?
hardware count is 1, set that to to right number of leds in the strip.
2025-09-13T16:10:48.019Z [hyperiond V4L2:/DEV/VIDEO0] (ERROR) Throws error nr: Cannot identify '/dev/video0' error code 2, No such file or directory
you have (seen by debug log) V4L2 video error.
and another thing, still running 2.0.0 Alpha version?
try to update packets with
sudo apt update && sudo apt upgrade -yand update Hyperion to 2.0.16
its possible there is a little corruption going on the SD card, sometimes SD cards will get corrupt (loosing data) for no reason.
it happened to me also
is data and clk connected on GPIO 10/11?
nothing of wires is loose there? check the connections and solder them (preferred method on GPIO)
with soldering no resistance on joints
Please more information.
i made the problems of v2.1.1 in a topic not long ago.
problems with restarting automatically every 5 min and USB grabber problems by other members.
note: mine was restarting behavior after i came from a update 2.016 to 2.1.1
Hyperion 2.1.1Support for 16-bit HD108 LEDs via SPI
nice. didnt know that was just build into the new release 2.1.1
but i still run 2.0.16 because of all the problems in 2.1.1
You really think that during movies you dont really see much of a difference between the two?
no i think after seen the SK6812 (not bad clone SK9822) and the HD107S the one isnt better than the other.
a plus is that the ledcontroller of HD107S is the APA102 and very easy to setup. Runs with a few settings altered, data/clk directly connected to GPIO 10/11 no resistors or capacitor needed. (i never used that in 3 years)
for SK6812 strips it CAN be a adventurous build to get them working, search here on the forum for SK6812 problems/troubleshooting
NodeMcu and/or similar like Logic Level Converter to boost the data from 3.3 to 5 volts can be unavoidable to use....
Some SK6812 are really sensitive for the right amount of DC volts on data line.
Either a rpi zero 2 or rpi 4.
go for a little more power, pi4 because rendering of images in Hyperion.NG takes a lot. I am running a Pi3b and on 720p it runs perfect with 25 FPS and decimal 3 setting
Any lower and image it starts to slow down and skip frames.
Anyway a Pi4 nowadays doesn't cost much anymore.
Dobly Vision is not a huge requirement for me but HDR10 is
you can't have HDR10 in a Hyperion.NG build when image is grabbed with HDMI/USB, you need a different fork for that >> HyperHDR Awawa dev
hd108 is 16 bits ledstrip, hyperion can not control this.
i have the HD107S ledstrip, ledcontroller APA102 can control this strip without hasle.
really bright colours and outstanding NC whites.
you dont need a separate white channel to have incredible whites. You need good strong PSU in DC5 volts and inject it at least at begin and end to the ledstrip
imo, the HD107S doesn't pale to the SK6812. they are competitive.
there's 2 tabs where you can change the hardwareledcount. Ledcontroller and ledcount. First set the ledcount tab 2 then you alter tab 1
oh you have analog strips probably. the one colour strips or 1 leds 🫢
https://pastebin.com/cYBdsf69 idk i just tweaked smth and it stopped working
but you have a backup, so put the orignal file back which you saved then restart Hyperion.NG
where do i find Json settings? Srry but im a dummy
in Webbrowser go to dashboard settings you can save in Json. You can open Json with texteditor
you configured adalight in Hyperion.NG as ledcontroller?
i think there's something wrong with the white settings in Hyperion.NG or/and sketch settings in Adalight
pclin can help you better with this.
provide your Json settings here from Hyperion.NG
cant see yt video unfortunately because of blocked content.
whats your setup? looks like you have to change the sketch from arduino or try different controller for wled.
use Adalight and ' play with white settings in this controller
put Json here or in Pastebin
i am not expert in Arduino builds..
its probably memory, leds are really sensitive about current flow. even if you touch it with a finger it will react.
what i did is a relais between the + DC pole to eliminate memory (thus stored current) on the leds. When I switch the relais 2 seconds everything goes black and stay black.
setup APA102 controller with HD107S leds.
also sometimes it will help to "drain " the first led with a 100ohm resistor/ will also help to protect the first led flowing to much current. And flatten out signals.. but anyway.... just place the resistor directly onto the GPIO10 in between the dataline DATA and strip. CLK isnt necessary because its only for timing purposes
