The project undergoes a significant transformation, building upon the initial groundwork laid in the previous stage. Notably, improvements are introduced in two key areas, enhancing the overall home automation and remote access system. Firstly, the system's remote access solution undergoes a crucial upgrade. Cloudflare Tunneling, specifically Twingate, is replaced by Tailscale-A secure networking solution. This change is implemented to fortify remote connectivity, ensuring a seamless and encrypted communication channel between virtual instances within the Proxmox environment. Tailscale's efficiency in networking is chosen to streamline and secure remote access. Secondly, the home automation platform sees a substantial advancement. The existing Home Assistant OS is upgraded to Casa OS, now deployed as a Docker image.
