The water tank controller
you install once and forget.
SwitchFlo is an automatic water level controller built to be wired in and left alone. It runs your motor from real tank levels, protects it from dry runs, overflow and bad mains, and keeps doing it whether or not the internet is up.
- Runs up to 2 tanks, 2 motors and a sump from one controller
- Dry-run, overflow and voltage protection built into the device
- Wired throughout, so there is nothing to charge and nothing to re-pair

Features
Everything your water system needs
Built-in intelligence that protects your motor, saves water, and handles the daily water routine so you don't have to.
Fills your tank. Stops itself.
Motor turns on when the tank runs low, off when it's full. Water level is the boss, not a timer, not a guess.
Dry-run protection that doesn't cry wolf
Confirms water has actually run out, not just a sensor blip, before cutting power. One tap in the app or one button press resets it.
Overflow? Not on our watch.
Auto-stop at full, confirmed by multiple readings so a single sensor spike never lies. No wet terrace, not a litre wasted.
Voltage protection, tuned for Indian power
Blocks the motor when mains voltage drifts outside the safe range: 195–260V by default, adjustable from 150–300V in the app.
Warns you before it cuts off
You get an alert while voltage is approaching the limit. After recovery, a 30-second cool-off stops the motor restarting into an unstable line.
Linked tanks, automatic backup
Two overhead tanks joined by a pipe? If the primary motor can't run, sump empty or voltage fault, the backup motor takes over on its own.
Every action comes with a reason
Motor stopped? The app tells you why: tank full, sump empty, schedule, voltage, dry-run, or you. No mystery switches.
Knows when municipal water arrives
The sump inflow sensor detects the moment supply starts flowing in, so you get an alert when water comes instead of finding out at 11pm.
Never runs blind
If a level sensor ever reads dead, SwitchFlo stops the motor safely instead of guessing.
Schedules that survive power cuts
Up to 5 time windows per motor, stored in the controller itself. Power comes back, SwitchFlo picks up exactly where it left off.
Never runs too long
A built-in safety timer, 60 minutes by default and adjustable, stops the motor even if everything else somehow fails. Timed manual runs stop themselves too.
Two motors, one brain
Runs your sump and borewell motors from one controller, single or three phase. Set which one gets first preference, or let SwitchFlo decide.
See every tank, every second.
Live water levels across all your tanks, sump, overhead, borewell, updated in real time on your phone.
Know before there's a problem.
App alerts for low tank, dry motor, overflow risk, the moment they start developing. Act before anything goes wrong.
Set it once. Let it run forever.
Configure your tank levels, schedules, and motor rules one time. SwitchFlo handles everything from there.
Power protection
Indian voltage is brutal. SwitchFlo is built for it.
Evening voltage drops, phase fluctuations, the surge when power comes back: these kill more motors than dry running does. SwitchFlo reads your mains voltage continuously and blocks the motor outside your safe range. Set your own limits from the app; they are saved on the device and survive every power cut.
A warning before the cutoff
You get an alert while voltage is approaching the limit, not just after the motor stops.
30-second smart restart
A cool-off after recovery means the motor never restarts into an unstable line.
No false trips
It knows the brief dip your own motor causes at startup and ignores it.
Smart fallback
Your backup motor, promoted automatically.
Many homes have two overhead tanks joined by a pipe and two ways to fill them: sump and borewell. Tell SwitchFlo the tanks are linked, and if your primary motor can't run, the second motor takes over on its own. Water keeps flowing. You find out from a notification, not from a dry tap.
Automatic takeover
Sump empty or voltage fault on the primary? The backup starts by itself.
Watches three tanks at once
Two overhead tanks plus your sump, each tracked at four levels: empty, low, high, full.
No mystery switches
It never just turns off. It tells you why.
Every motor start and stop carries a reason: tank full, schedule, dry run, low voltage, or a tap on your phone. When something happens at 3am, you don't wonder. You open the app and read exactly what the controller decided and why. That's the difference between an automatic switch and a system you trust.
Live levels, updated every minute
Tank levels, motor status, and mains voltage refresh every 60 seconds while you watch.
A live voltage meter in your pocket
See your actual mains voltage on a green, amber, red gauge, any time.
Configuration
Set it up once, exactly how your building works.
No two buildings run their water the same way. Everything below is yours to set, and once it is set you should not need to touch it again.
Time-based schedules
Up to 5 start windows per motor, kept by the onboard real-time clock and stored on the controller. Fill overnight, fill before the tenants wake, or both.
Auto start and stop
Hand it the tank levels and it takes over. The motor starts when the tank drops and stops the moment it fills, with no timer and no guessing.
Dry-run delay you set
Choose how long the controller waits to confirm water has actually run out before cutting power. Tune it to your borewell instead of living with false trips.
Maximum run time
A hard ceiling per motor. Even if every other rule somehow fails, the motor stops when its limit is reached.
Linked tanks
Tell SwitchFlo your two overhead tanks are joined by a pipe and it treats them as one system, choosing which source to fill from and which motor to run.
Light schedules
The included SmartSwitch runs gate lights, elevation lighting or any 230V load up to 1kW on its own schedule, from the same app.
Setup
Installed by a local electrician.
Usually done in 1–2 hours.

Sensor quality
Rust-proof sensors built for Indian water.
Engineered and assembled in Hyderabad. Cheap float and metal sensors rust or jam within months in hard Indian water, so SwitchFlo uses non-contact magnetic sensors instead. Nothing touches the water to corrode, they need no calibration, and they last years inside your tank.
-
Non-contact magnetic sensing
No probe sits in the water, so there is nothing to rust, corrode, or react with minerals.
-
No calibration needed
Drop in and it works. Designed to just work.
-
Plastic and concrete tank compatible
Works in all standard Indian tank types.
-
10m cable standard
Covers most 2-storey homes. Longer cables available.
The hardware
Compact. Enclosed.
Sits next to your switchboard.
The SwitchFlo controller mounts on any wall near your motor switchboard. It's enclosed, compact, and looks like it was always part of your electrical setup, not a DIY afterthought.

Real installations · Hyderabad
Installed in homes across the city
"All 4 floors need water at the same time when tenants leave for office in the morning. Motor used to run dry almost every day and we had no way to know. SwitchFlo handles everything now. Gate lights and parking are also on a schedule. Haven't switched the motor on manually in months."
"We had a timer starter already but overflow was still a problem. Tenants were starting the motor at any time and the starter kept burning out, replaced it twice in the same year. After SwitchFlo no overflow at all, no starter issues. I check water levels from my phone even when I am at office."
"Going up to the terrace 3-4 times a day was getting very difficult for me at my age. One time I forgot to switch off the motor and water overflowed for so long. Son got this device for us. Now I don't go up at all, everything happens on its own. Very happy with it."
"We have borewell and sump, with our two overhead tanks connected to each other like most homes. SwitchFlo decides where to fill from, sump if there's water, borewell if not. No more climbing up to check levels, we just forgot about the whole problem."
