It fills your tank while you sleep — and reads your motor's pulse while it runs.
Automatic tank filling, water and electricity savings, and instrument-grade protection for the motor your home depends on.
Every Indian home fights the same small war: the tank overflows, the switch gets forgotten, and one dry summer morning the motor burns. Legacy controllers flip a relay — and understand nothing about the machine they're switching. They fail in three old ways:
The simplest promise first: your tank fills itself, your motor is protected, and your phone knows everything — even when the internet doesn't.
Measures the tank with ultrasound — without ever touching the water. Solar-powered, wireless over LoRa. Nothing to corrode, jam, or clean.
Runs your pumps automatically, blocks dry runs and voltage faults, and keeps working fully offline — with manual override always available.
Live levels, remote start and stop, alerts, and history — from anywhere. WiFi at home, LoRa as backup, buttons as the last word.
While it fills your tank, WatrSync reads your pump's electrical signature — current, voltage, phase — hundreds of times a second, the way an ECG reads the heart's pulses and finds blockages before the attack. Legacy controllers switch. WatrSync diagnoses.
Engineers call the technique Motor Current Signature Analysis — the same diagnostics used on crore-rupee industrial turbines. WatrSync puts it in every Indian home, for the price of a water controller.
A dry run is a heart attack stopped in milliseconds. A dying capacitor is a murmur heard weeks early.
We just taught it to speak.
Water depth changes how a pump loads, and WatrSync hears it in the signature — a stethoscope into the earth. Sensorless sensing: groundwater level estimation without drilling, decay and recharge trends across seasons, borewell yield prediction, and a warning before a well runs dry. Zero downhole sensors. The motor is the sensor.
That's why it never fails.
Legacy controllers dip metal probes or a float into your tank — hard water corrodes the probes, scale jams the float. WatrSync measures with ultrasound from above the surface: non-invasive, nothing in the water, nothing to fail. And instead of two or three fixed points, it reads every level, continuously — the precision behind the fill curves, leak hints and overflow prevention.
It reads quality, too: connect the TDS probe and WatrSync tracks your water's purity live in the app — something no water level controller offers today. Add a flow meter on each line, and every litre is accounted for.
The same rooftop node that reads your tank reads your air. It already sits in the best spot in the house — solar-powered, on the roof, always on — so WatrSync turns it into a hyperlocal air-quality and micro-climate station, in a country where monitoring stations are dozens of kilometres apart.
Temperature and humidity today, rainfall next — the same box, more senses, delivered over the air.
One WatrSync protects a home. Thousands become a nervous system for India's water — hyperlocal groundwater maps, air quality, rainfall and usage patterns: the invisible utility, built as a side effect of a product people buy for convenience.
Every install makes the water map of India sharper — and nobody else has a reason to be in the home to collect it.
Investors: the wedge is convenience, the asset is the install base — a sensing network customers pay to deploy.
REQUEST THE DECKThe instrument pays for itself in the boring ways first — water that never overflows, electricity that never idles, a motor that never burns.

Think of it as motor insurance that costs less than one rewinding.
Bought separately, they'd cost more — and never talk to each other. WatrSync is all five, in one box that thinks.
We're not selling a box.
Installation by the WatrSync team, an on-site demo for your family, and five years of peace of mind — on us. You never need to find an electrician.
Join the launch list for priority installation, early-bird pricing, and a controller that gets smarter every month you own it.
Yes — WatrSync supports single-phase submersibles, monoblocks and openwell pumps, including dual-pump setups. Three-phase support is on the roadmap.
Nothing changes. The controller's logic runs fully offline, the rooftop sensor talks over LoRa (not WiFi), and physical controls always work. The app simply catches up when you're back online.
No. The WatrSync team installs it, gives you a full on-site demo, and hands it over running — typically in under an hour. Installation, demo and service are part of the product, not your problem.
Yes. A flow meter on each house's line gives every home its own live meter. The app shows each house's water use and pump-electricity share, and computes every bill automatically — no more splitting by guesswork.
Yes — WatrSync supports TDS water-quality sensing. Connect the TDS probe and the app shows your water's purity live, tracks trends over time, and tells you when your filter needs attention.
A pump running dry has a distinct electrical signature — current, power factor and load change within moments. WatrSync reads that signature continuously and cuts power within milliseconds, before heat damages the seals.
