Yup, I have a domain I purchased and on my lan I use PiHole and Caddy. All my apps and services use the format app.mydomain.com. PiHole forwards all requests for *.mydomain.com to Caddy, which handles the LE certificate (via DNS challenge) and forwards the requests to the proper IP:PORT. I started using this for everything, my Proxmox hosts, printer, my APs…
I use Aegis, which I periodically back up manually off phone.
