Automation ideas

💡

Arrive & illuminate

Door opens → garage lights on. No stumbling in the dark. Lights off automatically once the door closes again.

❄️

Protect your HVAC

Door open > 10 minutes → pause the AC. Stop paying to cool the neighborhood when someone forgot to close up.

🎬

Welcome home scene

Phone at Home flips on → disarm alarm, set thermostat, turn on entry lights, play your arrival playlist. One trigger, everything ready.

🚨

Security: door left open

Nobody home (Phone at Home = away) + door open → instant notification. Add auto-close for zero-worry security.

🌙

Goodnight check

Bedtime routine checks door state — if open, close it automatically and send a notification so you know it was handled.

📊

Your ETA on the dashboard

Phone Distance sensor on a Lovelace card shows how far you are from home in real time. Start dinner at 5 km, warm the garage at 1 km.

🚙

Car or truck?

The sonar reads a different distance depending on vehicle height. Use the Garage Distance sensor in an HA template to tell whether the car or the truck is parked inside — no extra hardware.

🏗️

3-bay dashboard

One Lovelace card per bay — Left Bay, Center Bay, Right Bay — each with its own cover entity, car sensor, and distance gauge. Full 3-car garage at a glance.

SproutKeeper

SproutKeeper is a complete growing system — the SproutHub receiver, SproutPod range extenders, wireless 433 MHz soil / weather / rain sensors, and smart plugs, all working together. Power it on and your sensors appear at sproutkeeper.local — no pairing, no Bluetooth, no Zigbee.

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.

Power a USB mini water pump or USB grow light directly from the SproutHub or from a remote SproutPod — automatically triggered by soil moisture, temperature, light level, or any other sensor reading.

About OzBits

Built by makers,
for everyday people.

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.

🏠

Local First

Your devices work on your network without phoning home. No cloud dependency, no account required for core features.

🔔

Alerts That Matter

Voice calls, SMS, and email notifications when something needs your attention — not endless push notifications for nothing.

🔧

Easy Setup

Plug in, connect to Wi-Fi, open a browser. No app downloads, no complex configuration, no special hub required.

🔄

Always Improving

OTA firmware updates keep your device current long after purchase. New features ship automatically.

Our Philosophy

Local-first, always.

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.

🏠

Your network, your rules

OzBits devices run entirely on your local network. No data leaves your home unless you choose. No account required for core features.

🔓

No lock-in

Open protocols — MQTT, HTTP, REST. Your devices work with Home Assistant, Node-RED, and any tool you already use. We don't build walls.

🛠️

Maker-built

Built by engineers who got fed up with overpriced, overcomplicated IoT. We make things the way we'd want to use them.
