use twisted pair cable like CAT6 FTP for the ledstrip data and thick(er) gauge of red and black wires for 5v and GND

CAT6 4x2x0.8

Red and black AWG 10 or lower

---

I have steered the leds in my window from the PI with FTP. More than 5 mtr, no problem

---

connect the shield of FTP at PSU side at GND/ V-

Wow! Really?? I will need all 8 wires of CAT6 just to be able to push data signal 8 feet? And I can't use 14 guage for power for 8 feet, it has to be 10 guage? If so, 10 guage for each for both power injection points or 10 guage can feed both points?

I just put together a Hyperion 2.0.12 + Raspberry Pi 3b + generic USB capture device + WS2812B (5 volts, 177 LEDs) setup. Unfortunately I can't fit/hide all the devices and all power supplies behind the wall mounted TV, so I have unsightly wires going from the TV to the top of the hole in the floating media console. For me to be able to hide everything I would need to put all the devices and power supplies in the media console and run ~8 foot of data & 2x positive & negative wires (for power injection) in the wall to the LED strips on the back of the TV. With the max current usage being 8 amps (when all 177 LEDs are white, max brightness), how can I safely run ~8 feet of data and 2x power wires in the wall without the LEDs suffering from brightness and performance issues?

Why not doing a test yourself, find out and report about it?

you can't do any harm with trying, the Pi is only hardware.

Worked without a hitch. I didn't change anything in config.txt as I didn't want the Pi potentially generating any additional heat - it's in a basic Pi case and mounted a cm or two from the wall due to the low profile TV mounting bracket.

Thanks!

I have a Hyperbian installation on a Raspberry Pi 2, but one of my Raspberry Pi 3's just became available. Can I simply take the micro SD card out the Pi 2 and put it in the Pi 3 or do I need to do anything special to get that same Hyperbian installation booted and running successfully intact in the Pi 3?

I installed Hyperbian on a Raspberry Pi 2b and got the LEDs dancing successfully via WLED and ws281x/RPi PWM controller types. It's noticeably laggy compared to the RPi 3, but my RPi 3's are in use for other priority installations. I do have an Orange Pi 3 and a Rock Pi 4c sitting unused, so I figured I try Hyperion with them. I installed the latest versions of Armbian on both, installed the nightly version of Hyperion, but can only get WLED controller type to work on both - ws281x does not light up the LEDs when connected via GPIO pins. Hyperion is running as root on both. Hyperion log has the following error message on both:

[LEDDEVICE] (ERROR) Device disabled, device 'ws281x' signals error: 'Failed to open. Error message: Hardware revision is not supported'

Any idea how to resolve this error and get LEDs working via GPIO pins on these devices (or via anything faster than WLED)?
