Thanks @pclin, this is great information!
I further looked at it and you are absolutely right. It would be best to root the TV. You could install all the stuff in dev mode alone, but since the dev mode is temporarly, you'd want to really root the TV.
OK, updated way to go:
Higher level:
[LG TV --> PiCap --> Hyperion) --> over WIFI to --> ESP32 --> WLED --> WS2812 ECO 5M 300 LEDs
1. Software
Please correct me if i am wrong, but as is see it, this should be the way to go.
You have it rooted, right? I have a 2018 OLED65C8LLA with WebOS 05.50.10.
Which WebOS Version do you have and is homebrewchannel starting the SSH server on reboot?
I think I will have to just do it at some point and tackle questions when they come up^^
Nevertheless, the plan is to run PiCap & Hyperion directly on the TV, which eliminates the need of a RaspberryPi.
2. Hardware and wiring - Still, the bigger pain point.
Please review those parts:
LED Netzteil MeanWell LPV 60 5 Schaltnetzteil
AZDelivery NodeMCU Development Nachfolgermodell ESP8266
BTF LIGHTING Individuell adressierbar Vollfarbiger DIY Projekte
Q:
1. Do you have an opinion against the "ECO" versions of WS2812B?
- As described here it should be irrelevant if you use the non ECO or ECO version, right?
2. The biggest question mark still is the level shifter topic. Please take a look at the attached image, which is from here.
Isn't he using the ESP8266 (Wemos D1 mini) without a level shifter on WS2812B LEDs?
When you go to https://www.wemos.cc/en/latest/, it says, that all the digital outputs operate at 3,3V.
So, that confuses me a lot.
Also he uses a 470 ohms resistor instead of the 62 in your wiring diagram.
Thanks for your help in clearing up those pain points so I can start
