My question is: How can I access files on a external USB storage device with A Raspberry Pi with Hass.io?
Good question, i have seen some projects where they use downloaded media files who are located in a folder by http://hass_local_ip:8123/local/your_file.mp3 so i think you could create a hyperlink from your storage drive to your Rasp Pi and access it from this URL
I have the same question… anyone?
