I have set up let's encrypt with DNS challenge running a wildcard in on a subdomain. Its not a recursive wildcard, but for me, it works good enough. Some of the software I host in my home network expects to run as the root on a web server.
The DNS wildcard points to a 192.168.xxx.xxx address. I don't really care that the IP adres of my home server is public :)
