After spending quite some time figuring out how to set up SSL encrypted DDNS access for my Home Assistant, I’m thrilled to share my success story! I wanted to enable remote access to HA using Google Assistant, and the process was definitely a learning curve.
I started by leveraging my Asus router’s built-in DDNS service, which made obtaining the necessary certificate files straightforward. The domain I’m using is through AsusComm, which simplified things a bit. I exported the cert.pem and key.pem files from the router and attempted to integrate them into my Synology NAS setup. It worked seamlessly there, with a green SSL icon appearing in Chrome—a great sign!
However, when I tried applying the same method to Home Assistant, I ran into some roadblocks. I explored the Let’s Encrypt plugin and manually added the PEM files to the config directory, but both approaches threw errors. It was frustrating seeing something work perfectly on Synology but not on HA.
After some research and trial and error, I discovered that the way Home Assistant handles SSL certificates differs slightly. I had to ensure the files were correctly named and placed in the right directory. Once I adjusted that, everything fell into place! Now, I can access HA remotely with a secure connection, and it feels like a significant accomplishment.
If anyone else is tackling this, my advice is to double-check file names and paths. It’s also worth exploring community forums or documentation for any specific tweaks needed for your setup. Happy configuring!
