Control Freak Water Supply, brought to you by Control Freak.
A complete kit of its own.

Concept Demo values are simulated.

Sound familiar?

Water for the house comes first.

The taps told you too late.

See gallons, percent and estimated days left before the tank is empty.

The sprinklers used the buffer.

Pause irrigation below your chosen level. Stop the booster below its low water floor.

The pump stopped. Nobody knew.

Hear a local alarm when water is low. Phone alerts can reach you by push, text or email.

How it works

Your tank. Your levels. Your rules.

Tell it about your tank
Enter tank size and shape, then set empty and full points for readings in gallons.
Choose the limits
Set the booster floor, irrigation pause level and pump house temperature rule.
Let the controller keep watch
Level, floats and temperature feed local rules. Days left is an estimate based on the last week of use.

What makes it different

A shared view of your water supply.

Rules stay here.

A Wi-Fi or internet drop changes nothing about the rules running on the controller. The local alarm still works while powered.

See an unusual drop.

A falling faster than usual alert tells you to check for a running hose, a leak or unexpected use. It does not identify the cause.

Watch the pump house.

A temperature probe warns about freeze risk. A connected heater can switch on below your set temperature.

What's included

One complete kit of its own.

Controller, the outputs and sensors this product uses, and Home Assistant built in. It can also run from a Pool controller’s spare outputs.

Level sender or house pressure sensor: choose one
Low water float and overflow float
Pump house and outdoor temperature probes
Local siren and water supply control outputs
Switching for a compatible 120 V booster and pump house heater

Your tank, pumps, heater, contactor and solenoid valves are not included. Confirm equipment compatibility before installation.

Home Assistant

Your water supply, with the rest of home.

Home Assistant built in. No subscription. See water readings and controls together on your home network.

Alerts you can hear and read

Choose push, text, email or alarm. Phone alerts need internet. Controller rules and the local alarm do not depend on Wi-Fi or internet.

Honest limits

Know what it watches.

One reading in the base kit.

Choose one level OR one house pressure reading, not both. This demo uses level. It does not test water quality.

Short cycling? Check the bladder tank.

This kit does not monitor pump cycles or the bladder tank. Keep your existing pump protector.

Installation and power matter.

A 240 V well pump needs an electrician and a contactor. Rules and the alarm need power. Freeze watch cannot guarantee pipes will not freeze.

Try it here

See what happens when water gets low.

Try low water, a fast drop or a cold night. Every reading is simulated.
