OzBits builds connected devices that monitor your space, protect what matters, and keep you informed — from anywhere in the world.
From plant care to home safety — OzBits devices work locally, send you alerts, and give you control from anywhere.
Your garage, always under control. Garage Minder monitors your garage door in real time and lets you open or close it remotely — from your phone, your smart home, or automatically when you arrive or leave. Voice call alerts, geofencing, door history, and Home Assistant support all built in.
📱 Open Web App →Works on any phone — install from your browser, no app store needed.
Enter your broker address in the app once — Garage Minder publishes full discovery configs automatically. Five entities per bay appear in HA instantly, no YAML required. In a 3-car garage each bay gets its own named set of entities.
One plug that works with every OzBits product — SproutKeeper, GrowSense, Stove Guardian, and more. Auto-discovered the moment it powers on. No cloud account, no monthly fee, no internet required.
Introductory price $19.99 — retail $29.
Shop Smart Plug →Passive 433 MHz monitoring for gardens, greenhouses, and grow rooms. GrowSense listens to wireless soil, weather, and rain sensors out of the box — no pairing, no Bluetooth, no Zigbee. Just power it on and your sensors appear on the dashboard at growsense.local.
Everything runs on your local network. The dashboard, automations, and smart plug control all work without any cloud account — because your plants don’t need the internet to get watered.
Peace of mind for your kitchen. Stove Guardian monitors your stove and sends you an alert if it's been left on — so you never have to wonder "did I forget to turn it off?" from the office, school, or across town.
Just say the word. CallCue is a voice-activated alert system that lets someone call for help from another room — no phone, no app, no button. Say the trigger word and an instant alert beeps, flashes, or vibrates on a nearby receiver. Ideal for home care, workshops, garages, and anywhere hands-free assistance matters.
OzBits started with a simple problem: why is smart home technology still so complicated, expensive, and dependent on apps and cloud subscriptions you don't control?
We build devices that work the way technology should — reliably, locally, and without requiring a monthly subscription just to turn on a switch. Every OzBits device runs its own web interface, works on your local network, and sends you alerts when it matters.
Currently based in the US, we're a small team shipping our first products and building the lineup one device at a time.
Your devices work on your network without phoning home. No cloud dependency, no account required for core features.
Voice calls, SMS, and email notifications when something needs your attention — not endless push notifications for nothing.
Plug in, connect to Wi-Fi, open a browser. No app downloads, no complex configuration, no special hub required.
OTA firmware updates keep your device current long after purchase. New features ship automatically.
OzBits is a technology company specializing in smart home and Internet of Things devices that prioritize local-first control over cloud-based subscriptions. Our product philosophy centers on user privacy and independence, offering hardware like the SproutKeeper plant monitor and specialized smart plugs that function without external accounts or internet dependencies.
Our roadmap spans kitchen safety sensors, garage controllers, and commercial-scale agricultural tools designed for professional fleet management — all built around open APIs and straightforward web interfaces, for consumers who want reliable automation without the subscription tax.
OzBits devices run entirely on your local network. No data leaves your home unless you choose. No account required for core features.
Open protocols — MQTT, HTTP, REST. Your devices work with Home Assistant, Node-RED, and any tool you already use. We don't build walls.
Built by engineers who got fed up with overpriced, overcomplicated IoT. We make things the way we'd want to use them.
The story behind why we build the way we build — and why local-first matters more now than ever.
