My question in short: How can I set the SSL certificates that Home Assistant OS uses?
I am running Home Assistant OS on a Raspberry Pi. My domain setup is a bit complicated: I use DuckDNS in order to get a a subdomain name, let’s say it is example.duckdns.org.
My domain provider allows me to edit the nameserver (but sadly I cannot use Let’s Encrypt with the DNS challenge), so I set a CNAME entry to have a subdomain of my own domain point to example.duckdns.org, lets call it: myserver.example.org.
For various other things, I have a local server running that obtains Let’s-Encrypt certificates for various other subdomains, and that works fine. I have set it up to also obtain an SSL certificate for myserver.example.com, and that also works fine.
Now, Home Assistant OS is running on a different machine.
How can I make it use these certificates? Can I copy them somewhere where they are found?
I find nothing on this in the documentation, it just says “use the DuckDNS add-on”…
