Home Assistant is the automation and experience layer of the Barnes Home Lab: a local system for connecting devices, presenting useful state, coordinating services, and turning infrastructure into something a household can actually use.
The architecture is designed to be demonstrated, documented, and communicated clearly: a practical foundation for private smart-home control that can grow into a trustworthy, marketable local-first solution.
Independent field testing for the next generation of local-first home automation.
Hardware and software partners are invited to place real products in a transparent, community-facing evaluation environment.Home Assistant sits inside a wider Proxmox design where compute, voice, storage, networking, and recovery services have clear responsibilities.
The documented HAOS node uses 2 vCPUs, 4 GB RAM, and 32-64 GB NVMe storage. It has a primary LAN address of 192.168.86.251 and an isolated backend address of 10.0.10.1.
The compute node provides the services Home Assistant can coordinate or depend on while keeping the system locally operated.
The storage architecture provides the central file layer and preserves HAOS backups alongside configuration exports, database dumps, and service records.
The file structure reserves guides for the Home Assistant system, integrations, front end, media, network, Proxmox, security, climate, utilities, alerts, and resilience.
Each entry now represents one documentation hub, making the Home Assistant roadmap easier to scan, maintain, and expand independently.
