HA on Raspi3, can I control WS2812 LED strips connected to the Raspi GPIO?

Dear Forum,

I have my test system up and running on a Raspi3. Now I would like to connect a WS2812 LED Strip to a GPIO of the Pi. Electrically, I know what to do, still, is there a way to control the strip via HA? I did only find an Integration for GPIO and PWM, which is not sufficient…
