Use linux 'top' command with per core view (press 1) or preferable 'htop'. On Rpi 2/3/4 max limit is 400% (4 cores per 100%). The problem will occure when one of the core's usage is close to the 100% limit, not when overall usage is for example between 200-300% where each core if far from the individual limit.

Thanks to our colleague @mjoshd there is a HyperHDR integration plugin for Home Assistant. Check the details on the website of the project https://github.com/mjoshd/hyperhdr-ha Also you can test a HA plugin to install HyperHDR link (thanks @ihrapsa)

We do not support driving WS281x and especially SK6812 LED strips directly from the Raspberry Pi although it's theoretically possible: link. If you made it and it works, fine, but most of our users weren't so lucky. You should use external ESP8266/ESP32 (preferable with CH340G or CP2104 onboard) or better Pico/rp2040 with built-in or external 3.3V to 5V voltage level shifter.

Usage of WS281x/sk6812 LED strip with Rpi directly (PWM mode) requires root privileges. Otherwise you may get 'Error message: mmap() failed' (read more) ⚠️ The PWM method does not work on Raspberry Pi 5 due to significant hardware changes!

How can i install HyperHDR under Libreelec?

Automatic HDR tone mapping switching for USB grabber using webos/piccap

What do these HyperHDR performance statistics mean?

Alternative ARM platforms for Raspberry pi But why not try Intel N100 SBC, which offers overwhelmingly higher performance than RPi and affordable Windows 10/11 in which even screen capture works very well using hardware acceleration and stably (currently unachievable under Linux for quite a lot of configurations/distributions, unfortunately)
