@quentinv - That’s funny, I am in a similar situation. About 3 years ago, I built Hassio on a Docker VM in Proxmox (unsupported) and have been fiddling around with HA since them. Last week, I decided to rebuild using hassova, to get a fully supported install, because I am getting more serious with home automation.
I was going to do a RPi install, but found that there are proper VM images available. I could not get the KVM image to work properly, so I followed the instructions in this post:
It has been working perfectly since the install. Let me know if you have any issues, maybe I can help (I have been a PMX user for about 10 years, both personally and professionally).
I’ll take a look at Schedy (have not heard of it), but I would like to keep the install clean and as much ‘native’ as possible. I am hoping to do it in HA itself.
