Control everything. Share nothing.

Nemu

An open-source, privacy-focused smart home controller that keeps your devices and your data on your network.

Why Nemu

Smart home without the surveillance tax

Three principles that guide every design decision from the protocol to the controller running on your network.

Nemu looking calm while everything stays local

01

Privacy by architecture

Nemu is built so your home stays yours. Control runs locally, without shipping your life to someone else's cloud.

02

Local-first, cloud when needed

Prefer your LAN for speed and sovereignty. Reach your controller remotely only when you choose never as the default.

03

Open source, inspectable

Read the code. Fork it. Host it. Nemu is Apache-2.0 so you can trust what runs inside your walls.

How it works

Your home. Your rules. Your network.

A smart home stack that starts at your router and stays under your roof.

Run the controller at home
Install Nemu on hardware you control: a mini PC, NAS, or home server on your LAN.
Devices stay on your network
Lights, locks, and sensors connect locally first. Fast responses, no round trip to the cloud.
Control from your apps
Use a unified API over LAN. Your phone talks to your home not a distant data center.
Remote only when you want
Need access away from home? Opt into relay access on your terms. Off by default.
The difference

Cloud hubs weren't built for privacy

Most smart home hubs treat your house like a data source. Nemu treats it like yours.

Typical cloud hub

Someone else's cloud

Nemu reacting to cloud dependency
  • Device data routed through vendor servers
  • Works until the company changes terms
  • Automation you hope works
  • Your home profile becomes their product

Nemu

Your network, your controller

Nemu excited about local control
  • Control plane runs on hardware you own
  • LAN-first for speed and sovereignty
  • Open source: read, fork, and self-host
  • Remote access is optional, not mandatory
Features

Built for control, not surveillance

Everything you need to run a modern smart home without handing the keys to a platform.

Privacy by default
No telemetry-as-a-feature. Your automations and device state stay on your network.
LAN-speed control
WebSocket and HTTP on your local network: sub-second response when you flip a switch.
Real-time updates
Reactive subscriptions keep every client in sync without polling the cloud.
Unified device API
One protocol for REST, WebSocket, and relay envelopes: build once, connect anywhere.
Self-hosted controller
Run on your own hardware. No mandatory SaaS middleman between you and your home.
Optional remote relay
Reach your controller away from home only when you explicitly enable it.
Open source
