Home Assistant

Home Assistant is an open source home automation server. It has integrations for a wide variety of devices, and allows you to create custom dashboards for viewing sensor information and controlling your devices. If you want to access your Home Assistant instance from anywhere, but cannot port forward due to CGNATNetwork Address Translation performed at the level of the ISP's equipment. , making your instance publicly accessible via 44Net is one solution. Even if your home internet isn't behind CGNAT, it likely has a dynamic IP, which would require you to set up dynamic DNS for your instance to maintain consistent external access. A 44Net IP lets your instance be publicly accessible at a fixed IPv4 address for free.

The easiest way to make your Home Assistant instance publicly accessible is by setting up a single device tunnel. However, before you make it publicly accessible, there are a few security considerations. First, you should configure your firewall. See Firewalling Basics for help with firewall configuration. It's also desirable to set up Let's Encrypt, so that your connection to Home Assistant will be encrypted with TLS, and will have protection against man-in-the-middle attacks.
