Hi,
I just want to say that I did use another totally different approach. I saw, when I installed this build, that it is not like Hass.io which I really like. It was very convenient to use and setup additional services like Mosquitto, Samba share, DuckDNS with Let’s Encrypt for access from outside.
An excessive search led me to this post which uses a Virtual Machine inside Freenas. It was just like a Raspberrypi and in 4 hours I had everything working. (From no VM to a hassio VM and ported everything from my in-use RPI to the new VM).
Maybe this is also more suitable for other people.
Cheers,
Koen
