If you haven’t already seen my initial Hassio setup guide, please visit this link.

Step 1 – Install DuckDNS

You will need to install the DuckDNS addon with Let’s Encrypt support to obtain a valid SSL certificate and domain name for encrypted traffic. From within Home Assistant, click on the Hass.io page on the left hand side navigation menu and click on the add-on store.

Find DuckDNS and click install.

Step 2 – Create a token and domain name

Click through to DuckDNS website and select a domain name and generate a token

Step 3 – Update the configuration in the DuckDNS addon

Copy the token and domain name generated and update the configuration in the DuckDNS addon. These details should match exactly as was generated in Step 2. Make sure you have changed the accept_terms to ‘true’.

Example Configuration

{
“lets_encrypt”: {
“accept_terms”: true,
“certfile”: “fullchain.pem”,
“keyfile”: “privkey.pem”
},
“token”: “xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx”,
“domains”: [
“xxxxxxxx.duckdns.org”
],
“seconds”: 300
}

Step 4 – Update the configuration in the configuration.yaml file

Within the configuration.yaml file, uncomment the http: section and add in the details per the example below:

Example configuration

http:
base_url: https://xxxxxxxxxx.duckdns.org:8123
ssl_certificate: /ssl/fullchain.pem
ssl_key: /ssl/privkey.pem

Step 5 – Forward Port 8123 to Home Assistant

Within your router, you will need to forward port 8123 to your home assistant IP. If you haven’t already made your Home Assistant to have a static IP address, check my initial video for details on how to upload the network configuration via a USB memory stick.

Step 6 – Restart the device

Restart your Home Assistant by going to Configuration > General > Restart.

Step 6 – Connect via the external address

Your Home Assistant instance should now be accessible from the external domain specified in the previous steps. e.g. https://xxxxxxx.duckdns.org:8123
