I’ve instaled hass.io from https://github.com/home-assistant/hassio-installer on my rasberry pi 3Bb in docker. Now i want to redirect my rflink which I 've connected to rassberry pi by usb.
I read taht I have to change run command on a “docker” and add
–device=/dev/tty:/dev/tty

I don’t know how I can do it. Could you help me?
