FLUIDY – Your smart water hub for any build

Ultra-fast, precise fill-level measurement
Measures the fill level in up to four fresh- or waste-water tanks with pinpoint accuracy—whether standard or wheel-arch tanks.
Easy installation—for all tank shapes
Drill a hole in the tank, insert a watertight grommet, place the sensor on the tank bottom—done. Even wheel-arch tanks (usually hard to measure) become highly accurate—no complex calibration or specialist knowledge.
Flexible to customize, freely nameable
Name each sensor and tank as you like—everything is clearly displayed on the SmartKnob and in the dashboard.
Smart alarm and warning system
Set warnings in the dashboard to your needs—e.g., “too little fresh water,” “too much waste water,” or “leak detected.”
Extended sensing for water comfort
Supports temperature sensors—e.g., for clever energy saving on the boiler or for shower comfort. Optionally monitors water pressure—for maximum protection of your water system.
Real-time leak protection
A dedicated leak alarm system protects you from water damage: in case of a leak, the pump is shut off automatically.
Quick pairing & extremely installation-friendly
Connecting to the SmartKnob takes seconds—light and sound confirm it. Sensor leads are plug-in and secure; no tools, no crimping, no stress.
Clear dashboard, no extra app
All water levels, temperatures & warnings appear automatically on the SmartKnob and in the dashboard—right after connection.
Minimal weight, maximum protection
FLUIDY weighs only 105 g, runs very energy-efficiently, and is comprehensively tested to EU standards: fully protected against reverse polarity, overvoltage & much more.
Optimal measurement for every tank type—no calibration effort
Rectangular tanks: with two entries (height, volume) you’re ready immediately. Wheel-arch tanks: more and more tank profiles are integrated directly; complex calibration is completely unnecessary.
Developed with the community—for van-lifers and pros
FLUIDY was born from real exchange with build experts and true van adventurers—your ideas flow in directly.
Future-proof updates
FLUIDY stays offline to save energy; updates start automatically via the dashboard—either locally via file or (in future) online (OTA pull with confirmation).
