OpenHAB
Over 400 technologies and thousands of smart devices from any manufacturer, unified under one roof: openHAB is the vendor-neutral home automation platform with a pluggable binding architecture. Each binding translates a device or service into openHAB's clean abstraction: Things expose Channels, Channels link to Items, and Items feed a rules engine that runs your home. That engine meets you at your skill level: Blockly gives non-programmers drag-and-drop visual logic, JS Scripting (GraalJS with the openhab-js library) is the modern text-based standard, the classic Rules DSL remains supported, and JSR223 opens the door to Python, Ruby, and Groovy. Time- and event-based triggers, scripts, notifications, and voice control compose into automations of any complexity, and users report decade-old rule sets still running rock solid. The Main UI handles configuration, semantic modeling, and now built-in charting - no external Grafana required. Built in Java on Apache Karaf's OSGi runtime and stewarded by the non-profit openHAB Foundation, it requires no cloud to function: everything runs locally, talking directly to your devices. Optional connectors bridge to Alexa, Google Assistant, and HomeKit, with iOS, Android, and web apps for control from anywhere.
EverShelf
That yogurt hiding behind the ketchup expired three weeks ago, and the flour you bought "just in case" has been sitting in the pantry since last winter. EverShelf replaces mental guesswork with a structured inventory system that tracks every item across pantry, fridge, freezer, and custom locations with precise quantities, expiry dates, and consumption patterns. Scan barcodes with your phone camera to add products instantly, or let the Gemini AI identify items from a photo and estimate shelf life based on storage location. The dashboard surfaces expired items and upcoming expirations with color-coded urgency badges, while anomaly detection flags suspicious quantities and consumption predictions that deviate from your history. Opened products get reduced shelf-life calculations; vacuum-sealed items get extended dates automatically. The recipe engine generates context-aware meal suggestions from your current inventory, prioritizing ingredients approaching expiry so nothing goes to waste; each recipe includes step-by-step cooking mode with text-to-speech narration and timer integration. A smart shopping list auto-populates when stock hits zero and syncs bidirectionally with the Bring! app, with AI-estimated prices per item and consumption forecasts showing when you will need to restock. For Home Assistant users, a native HACS integration provides 22 sensors, expiry calendars, bidirectional todo-list sync, and voice assistant support for adding items hands-free. A dedicated Kiosk mode optimizes the interface for wall-mounted tablets with BLE scale integration. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
