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) 🚀 🆕

If you want to install HyperHDR on Libreelec, @ghr12 has created a script that should help you https://github.com/ghr12/hyperhdr 🆕

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) and the voltage level shifter. ⚠️

Usage of WS281x LED strip with Rpi directly (PWM mode) requires root privilages. Otherwise you may get 'Error message: mmap() failed' (read more) ⚠️
