A 100% local home AI platform. One dashboard for every device, every family member, and every automation — running entirely on your own hardware.
The problem
Every smart home device ships with its own app, its own cloud account, and its own subscription. Your home data is scattered across a dozen servers you don't control.
When the cloud goes down, your lights stop working. When they raise prices, you have no choice. When they sell, your data goes with them.
Nexum replaces all of it — one local dashboard that you own outright, running on hardware in your own home.
What it does
Built around the way a real household actually works — not around what the marketing deck promised.
Everything runs on hardware you own, inside your home. No data ever leaves the local network. No accounts, no analytics, no telemetry.
Each family member logs in and gets their own view — their own email, calendar, feeds, and preferences. One home, individual experiences.
Ring cameras, Tuya smart plugs, Honeywell thermostat, Vizio TV, Narwal vacuum, Bambu 3D printer, Z-Wave, Zigbee — one interface for all of them.
Ollama runs a local language model on your own hardware. Summaries, anomaly detection, and automation decisions — all without sending a single word to a remote API.
60+ background agents run continuously: news digest, device monitoring, anomaly detection, finance tracking, security scanning, and more — quietly working while you sleep.
FastAPI backend, React frontend, PostgreSQL database. Self-hosted on a CM5 single-board computer. Every integration is code you can read, modify, and extend.
How it works
Your devices talk to a server in your home. Your dashboard talks to that server. That's it.
Smart home hardware — cameras, thermostats, lights, speakers, printers — speaks to the local network over their native protocols.
A CM5 single-board computer on your shelf runs the FastAPI backend, PostgreSQL database, and Ollama AI engine — all local, all private.
Any browser on your home network reaches the React frontend. Each family member logs in to their personalized view.
Built different
Nexum isn't a venture-backed startup with a growth roadmap and a clause in the terms of service about selling your data someday. It's a home project that grew into a full platform.
Built nights and weekends on real hardware, with real integrations that actually work — because the person building it lives with it every day.
Claude Code is used as a pair programmer throughout development — pairing human taste and architectural judgment with AI implementation speed. Every line of code is reviewed and understood before it ships.
"I built this because I couldn't find anything that worked the way I wanted. So I built it myself."
— Ludwig Taveras, FounderThe privacy guarantee is architectural, not a policy that can be changed later.
Always monitoring, digesting, and acting — so you don't have to.
New integrations, features, and improvements ship continuously.
FastAPI + React + PostgreSQL + Ollama. Runs on a CM5 for under $100.
