Hassio RPi4 - GPIO LED status?

Hi,

I’ve got a Raspberry Pi 4 with Hassio. The Pi has the standard “power applied” LED. I’d like to setup an LED that specifies that HA is ready and can be accessed. Maybe red if not running, yellow if the network can accept SSH, and green if all services are running and available.

Any similar thing already exist?

Thanks,
Ambi
