Three modules. One cable. Zero fiddling.
Oquari isn't a cloud with an app — it's a controller: the program runs locally, on the device right next to your aquarium. The internet is an add-on — for remote viewing, not for keeping your tank alive.
The hub — brain of the system
Runs all the programs: temperature, lighting, top-off, dosing, CO2 and waves. Carries a full set of connectors for level sensors, flow meters, temperature sensors, lighting and pumps — plus a display with a rotary knob for on-the-spot control, no phone or computer needed. Connects to your network via cable or Wi-Fi.
Smart power
Eight metered 230 V outlets and two special protected heater channels. Switch any outlet from a schedule, the app or an automation — while Oquari meters the power draw of each device and the whole aquarium. All mains circuits are enclosed away from the water — the electronics and sensors run exclusively on safe low voltage.
The probe module
The eyes and ears of your aquarium: pH, redox (ORP) and two independent conductivity measurements — from RO water to full marine salinity. Isolated measuring circuits immune to interference from pumps and lighting, with calibration wizards that guide you step by step. The controller monitors electrode health and reminds you when it's time to calibrate.
The wizard takes you from the box to a running tank
You don't configure from scratch, and you don't read the manual cover to cover. Power Oquari on and the wizard guides you — a few simple steps and your aquarium is under control.
Pick your aquarium type
Freshwater, planted or marine — plus your tank volume. The controller selects proven presets on its own: temperature thresholds, top-off behavior, light plan and safeguards.
Name the outlets and pair the sensors
"Filter", "heater", "light" — pick names from a list or type your own. Temperature sensors pair through the wizard: dip the probe, and the controller recognizes and assigns it by itself.
Set a few numbers and you're done
Temperature, light hours, dosing amounts. You can fine-tune everything later — but you don't have to. Probe calibration can be done right away, or skipped and returned to later.

Four windows onto one tank — control it the way you like
On the device
A clear display and a rotary knob: parameter overview, feeding, alarm mute and basic settings without reaching for your phone. Wet hands are no problem.
Local panel in your browser
Full configuration from a computer or phone on your home network — no app to install, no cloud account. Always works, even without the internet.
The oquari.com panel
The same full panel from anywhere in the world, plus long-term charts and push/e-mail notifications. Optional — never mandatory.
Home Assistant
Your aquarium as part of your home automation: a full set of entities with no configuration. Logic and safeguards stay on the controller.
One configuration, shared across every window. A change made on the device shows up in the app immediately — and vice versa.
What runs where — and what happens when the internet goes down
Locally — on the controller
Everything your tank's life depends on:
- programs and presets: heating, ATO, water changes, CO2, dosing, light, waves
- safeguards: emergency cutoffs, limits, flood and level alarms
- the configuration panel in your browser
- Home Assistant integration (local, no cloud)
In the cloud — convenience, not a precondition
The oquari.com panel — for when you're away from home:
- a view of your tank and its history from anywhere
- push and e-mail alarm notifications
- remote setting changes and long-term charts
- when the internet goes down — you lose only remote viewing; the controller keeps working
