Incremental Setup on hardware

I'm planning to setup TV (Sony 55 X90L) backlight incrementally hence want to clarify on some points after watching some videos :-

• Have ordered ESP32 WROOM32 with mini usb to USB cable ,WS2812B(https://roboway.in/shop/ws2812…-5v-addressable-rgb-ip65/) this would be required to control led anything else required ?
• Does hyperion-ng needs to be running on rpi or can it be run on any device , as i have optiplex x86 device which i can install on ?
• Can i try whether it works with this set of hardware along with "Android hyperion grabber" on my sony android tv ?
• Or is capture card and hdmi splitter a must to work with it ? As i want to try without capture card and splitter before i proceed ahead.
• If i go ahead with capture card and splitter do i need to get high quality switch (http://bluerigger.co.in/product/hdmi-switches/ )as well as capture card or capture card does not any significance ? As i plan to use mostly for HDR and DV content.
• Lastly will this work with DRM apps as well ?

Got the wled setup but having issues with running with hyperion on dell optiplex with Ubuntu 22.04

<ERROR> Lock/unlock handler- Session bus is not connected

Also is rpi must or hdmi splitter and capture card can make the job done?

Thanks i just restarted everything and it seems working now any recommended setting i should apply ?

Im running hyperion on ubuntu server 22.04.3

It's only a message, Hyperion still works.

WLED issues?

What is in the Hyperion log, log-level debug, attach the log as a .txt file here.

An RPI is not necessary, Hyperion works on various devices.

Which OS runs on the optiplex x86?

Also not sure whether you can comment can it be used in hype rhdr without rpi?
