The aquarium server beside your tank
One hub for your entire reef.
Node One is not a tablet. It is an always-on local aquarium server with a built-in touchscreen. It connects compatible controllers, cameras, smart plugs, feeders, sensors, and automation devices, gathers their data around the clock, and turns it into one reef-focused dashboard.
Always on beside your tank, collecting supported data locally
See the dashboard at home and selected reef data through Reef Trak when away
Control supported smart plugs and pump switches
1 TP-Link Tapo smart plug and Reef Trak Premium lifetime code included

What is Node One?
The computer that stays with your reef.
The touchscreen is only the built-in display. Behind it is a full Raspberry Pi 5 server running Node OS: connecting compatible systems, collecting their readings, storing local history, and keeping your reef dashboard available even when your phone is somewhere else.
At the tank, open Node OS. Away from home, open Reef Trak to check selected readings and history. Either way, Node One is the hub doing the work beside your aquarium.

Node One runs locallyThe always-on server gathers data, stores history, and runs supported controls beside the tank.

One place for compatible equipment
Bring the equipment you already own.
Node One is not here to make you replace everything around your tank. It is the reef-focused place where supported integrations and compatible devices come together for monitoring and local control.
Collect
Node One stays on beside the tank, gathering equipment state, sensor values, connectivity, power use, and local history.
See and control
Use one Node OS dashboard to understand the reef and operate compatible smart plugs and pump switches through supported controls.
Access
See the dashboard on Node One at home, or check selected readings and reef history through Reef Trak while you are away.
This is the centralized reef hub people keep asking for.
Compatible pumps, heaters, lights, cameras, feeders, smart plugs, sensors, controllers, and automation devices can surface through one reef-focused system instead of staying scattered across unrelated apps.
Check your exact equipment.
Compatibility varies by model and connection method. The maintained list separates supported connections, previews, and equipment that is not ready yet.

A complete reef picture
Your equipment and your reef data belong together.
Node One collects what supported equipment is reporting beside the tank. Reef Trak carries selected readings and history to your phone or browser, so checking the reef from work does not require reaching into six separate apps.
- Water parameters
- Test history
- Maintenance reminders
- Equipment status
- Alerts
- Aquarium history
At home or away, ask one question: “What is happening with my reef?”
Node One is the always-on hub gathering the answer.
Power and control
Local control with useful power context.
Node One can switch supported equipment locally, watch its reported state, and use available power readings to help confirm the response.
Monitor power
Track actual power usage reported by supported devices.
Control supported switches
Turn compatible smart plugs and pump switches on or off from Node OS.
Use response feedback
Use available power and state telemetry from supported hardware to help confirm equipment responded as expected.
A state value says:“The device reports on.”
Power telemetry adds context:“The device reports on and is drawing power.”
Telemetry is not infallible physical verification, but it can provide useful evidence that equipment started, stopped, or is drawing significantly less power than expected.
It is your computer

No subscription. No yearly hardware fee. No charge just to keep using the computer you already bought.
Node One is your hardware. Reef Research Labs intends to make the necessary display and video drivers available so owners can repurpose the Raspberry Pi hardware if Node OS is removed. Third-party operating systems and repurposed configurations are outside official Node One support.
