“Home cloud” is not a single product — it is an idea: compute and storage you control, usually on your network, serving you first instead of a distant company’s business model. Coffee Home is our playground for that idea in HTML and apps you can run locally or on a small machine at home.
A home server is a computer that stays on (or wakes on demand) on your home network and runs services for you: files, backups, media, chat bots, dashboards, or static sites. It can be a Raspberry Pi, an old laptop, a NAS, or a small PC. It does not have to be loud or expensive — it has to be yours and reachable on your LAN (and optionally, carefully, from the wider internet).
People often say “cloud” when they mean “someone else’s computer.” A home cloud flips that: the cloud-shaped convenience (apps, sync, dashboards) can live on your hardware, with rules you set.
When your photos, messages, notes, and habits live only inside a free app, you are usually paying with lock-in and surveillance capitalism: the provider can change terms, show ads, train models on your content, or disappear. Owning your data means you have copies, exports, and ideally a place you control where the canonical version lives.
You do not have to self-host everything overnight. Even one folder synced to a disk you own, or one chat log you can export, is a step toward agency — the ability to move, delete, or share on your terms.
Ethernet is a family of wired standards for local networks: devices plug in with cables (often RJ45) and talk at high, stable speeds with low jitter. Your router’s LAN ports, many NAS boxes, and desktop PCs use Ethernet. It is the plumbing that carries IP traffic on your home network.
Wi‑Fi is wireless Ethernet at the human level — same kinds of packets, different physical layer. For a home server, wiring Ethernet when you can (server ↔ router) keeps backups and media streams smoother; Wi‑Fi is great for phones and laptops moving around.
Coffee Home does not require you to crimp cables; understanding Ethernet helps you see why “on the same LAN” matters for opening local URLs like http://192.168.x.x or running a static site from a folder.
Coffee Home (COFFEE-HOME) is a desktop-style hub: a dock and an app grid that open real pages in iframes — Grind, Social, Geek Store, KIP Chat, and tiles like Nimbus “Home Cloud” and Server. That layout is a metaphor for a home OS: one place to launch the tools that could eventually run against APIs and files on your own machine.
Reality check: not every tile in Coffee Home is a finished product yet. The core is the shell, the wiring, and a few real surfaces. This module sets vocabulary so when new apps land, you know where they sit in the home-cloud story.
