HUE spots, in different Chamber settings.
I run Hyperion.NG 2.013 plus HUE bridge
I have the spots/bloom and playbars of HUE
Switch off black is activated with all of them
I altered the led section because standard settings didn't do it for me

Could you help me with these points:
GPIO10 SPI controller WS2812
- Are you talking about gpis in raspberry? I have nothing connected to other gpio. only GPIO18
Then you have to run Hyperion.NG under root and switch off audio in config.txt
Ledcontroller to use is ws281x
Turn off white algorithm
extending the SPI buffer is not necessary when running on GPIO18 and PWM ws281x ledcontroller
-
they will draw approximately on 100 brightness a maximum of 15Amps
You can run them on 2 ledcontrollers buikd in Hyperion.NG
GPIO18 PWM controller WS281x
Run Hyperion under root privileges
GPIO10 SPI controller WS2812
More then 255 leds, extend SPI buffer in cmd line
make sure u use a common GND for ledstrip/pi/PSU
Settings correct in ledcontroller setup? Uncheck the white algorithm function
-
try it on Windows pc, if the grabber works there

I think you can achieve this with tab setting Signal Detection in expert settings.
You can alter this for each instance separately if I am not mistaken... settings you can find on this forum

1. 60l/m is suffient but try it out is my advice if you want to know, it's realllllyyyy bright and takes away the TV 📺 image 😉
2. Use the same PSU, at full (white) brightness it will draw a max around 38/40Amps. 50Amps so 250watts >>> Meanwell type is what you can order, with this you can power the Raspi also...
Don't cut the strip but leave it in one piece if possible, import 5v and GND in 4 points. Divide by 4. Beginning, end and 2 more middle points.
Use the already soldered points 👉 to injection power.
3. No, the current will flow from different injection power points/joints to GND so that's not a problem.
Use fuses in tour build, especially with 144l/mtr builds.
If you decide and go for 60l/mtr then you need a 20 Amps PSU on 5 volts ofcourse
Goodluck!
Ps you can see my build how I did it with 5 mtr of HD107S leds 60l/mtr.
Brightness 🌞 is more than enough on Samsung 4ktv 65" approximately 3" from the wall..

Or put a Groud Signal from the PSU on the RPI3? (didn't the USB provide the same ground?)
Its always recommended to do that, potential should be equal on ground. So you connect GND/V- /0V from PSU + ledstrip + Raspi together
-
Yeah,
HDR and Hyperion.NG don't work together, you have to switch of HDR when using Hyperion.NG.
HDR uses colourpallettes which Hyperion.NG doesn't understand. So that's the black and white explanation.
Your grabber is fine
there is a fork though HyperHDR which is alternated Hyperion.NG and can cope with HDR.
But no helpdesk on this forum.

probably a HDCP problem, for this I used a HDCP compliant splitter on output 1 of my Denon AVR
Look also in (expert) settings of Hyperion.NG at grabber section tab, resolution not higher than 720p and 25FPS. Decimation at maximum of 2 or 3. Not 0
Goodluck
-
you selected WS2801 as ledcontroller and that's a SPI controller. For GPIO18 you need WS281x ledcontroller on PWM. To run on PWM you need to run Hyperion.NG in root and deactivate audio in config.txt
Or you can run it by GPIO10 on SPI ledcontroller WS2812
For specific settings search on the forum

take a look at powersupply, it has to be powerful enough to feed the PI and USB grabber.
at least 2 Amps you need on 5 volt
-
if you use it then in series with GPIO. Buy it on AliExpress or something. 0.25 watts is enough
-
the resistor of 100R (in that ballpark) prevents the lights to be floating.
No signal to the lights and flickering? then you need resistor for PWM. The resistor is also used to prevent the first led having to much current flowing tru it, and burns
-
But if i am not mistaken the issue can only be caused by the power supply, since a different one is working properly?
PSU needs to have earth connection on the power socket. So L + N and earth.
Seems that PSU isn't grounded correct like pclin said, I think the same
-
yes because it's DC voltage it doesn't matter, and you won't have a potential difference/voltage drop at the end.
Mostly after 150 leds you have to power in 2 or threefold points on the strip.
I don't know what the problem is with the flickering, it only happens with switch the PSU?
I suspect 🤨 the CPU, I only use Meanwell.
A led strip is really sensitive for faulty DC, measure AC must be 0 !! If you measure AC then rectifier isn't good...
Goodluck
-
it doesn't but colours is more vibrant.
For reference: I have 300 leds type HD107S and at full brightness they use a maximum of 14A included the Raspi.
And yes I powered from both sides because of fading and yellowing colours
it's actually 3 points, begin middle and end.
-
measure voltage. Must not exceed 5.2 volts with load. Make sure you have a solid and soldered GND.
Power the strip from both sides with +5 volt and GND.
-
it works now? Good day sir 👍
-
turn off HDR and/or Dolby Vision in one or all the devices and try again.

WS2801 runs normally on SPI controller. On a Raspi pins 19 en 23 for SPI0, what is a lowboard?
