Finetuing / Several small problems

Hello together,

recently I've finished my Setup and now facing some small problems.

Overall its working, but with some issues.

Setup is following:

- Raspberry Pi 3 with Hyperbian (Wi-Fi connection)

- Az-Delivery Amica 8266 with WLED (Wi-Fi connection) ( AZDelivery NodeMCU Amica Development Compatible )

- Level Shifter (Amazon) -connected to Vin on Amica (around 4.5V)

- Power Supply 5V /20A ( https://www.amazon.de/gp/product/B07PQT2Q7L?tag=hyperioforum-21&ie=UTF8&psc=1 ) -set to 5.125V

- SK6812 mounted to TV (Ali-Express) - 244Pixel in total (79 / 43 / 79 / 43)

- HDMI Splitter EzCoo ‎ EZ-SP12H2 ( https://www.amazon.de/gp/product/B083JVPXDY?tag=hyperioforum-21&ie=UTF8&psc=1 )

- HDMI to USB 3.0 Grabber ( https://www.amazon.de/gp/product/B09QLWWDY9?tag=hyperioforum-21&ie=UTF8&th=1 )

- HDMI Cables capable of HDMI 2.1 (Amazon)

- Power supply poweres SK6812 Strip (one entry point), Raspi 3, HDMI Splitter and Amica Controller

- Datasignal actual with DuPont-Cable through Level Shifter

- HDMI Signal comes from my Pioneer AVR, to the HDMI Splitter and to the TV. No Signal Issues, No quality loss. Even HDR works flawless.

So this Setup works fine, but with some glitches.

Problems:

- Around 1 second lag of Ambilight to Picture on Screen

- Sometimes! flickering. But Only Blue! And only on later Pixel (around 150 and up)

- Amica stops working with Hyperion for no reason, sometimes it stays blank (dark), sometimes it falls back to WLED solid color.

I played around with resolution and Smoothing, but it makes no notiable difference (i think)

So what are your suggestions to this?

Where can i pimp my setup?

(Yes, i know, Data-Line could be better, I'm open for suggestions!)

Thanks in Advance!

Hello,

thnaks for the advises.

I will power the strip from both sides in the future... actually the TV is mounted to the wall and hard to dismount for me alone..

As the problem with disconnects and flickering stays i tried to use the SPI port on my Raspberry Pi.

And it works completly without any issues!

The lag is reduced to a very calm minimum and i have no Problems with flickering or disconnects or anything.

I used a DuPont Cable (20cm) wihtout resistor or capacitor direct to the Dataline on the Strip and it works great.

Just had to change the RGB-order in Expert Settings.

The only little problem is that in Standby-patternit flickers sometimes. But maybe this is due to my very cheap noname SD-Card.

For example, when using the Pac-Man-pattern sometime half of the strip flickers. But not everytime and if using Videocapture it works flawless.

So good enough for me! Thanks for the help out here.
