Residential monitoring for your property

Why homeowners and rental owners use it

Cistern surprises usually happen too late.

On St. John, water planning is easier when the cistern story is visible before a household, guest, or rental turnover feels it.

Less guessing

You should not have to open a cistern or wait for a problem to know whether the reserve is getting low.

Rental and guest changes

Guests, cleaners, laundry, and normal household use can shift water demand quickly.

Rain reality

Rain may help, but owners still need to know what recovered, what did not, and whether delivery timing changed.

Earlier service planning

Delivery and service calls are easier to coordinate before the cistern is already at an urgent level.

Simple water status

See the residential sample view before you need the details.

The sample residential view shows cistern level, gallons, trend, daily use, status, and recent water or rain changes in one place.

What monitoring helps you see

Eight things your cistern tells you.

Residential monitoring turns sensor depth into practical answers for household water decisions.

Water level

Current measured cistern level without opening the tank.

Gallons / percent

Depth converted into a plain reserve estimate for the property.

Days remaining

Whether the planning window is comfortable or tightening based on current draw.

Usage / draw

See whether the property is using water and whether that pattern looks normal.

Leak or unusual-use signal

Spot unusual draw early so fixtures, lines, or guest usage can be checked.

Rain recovery

Confirm whether a rain event actually improved the cistern outlook.

Alerts

Warning before low-water risk becomes a household or guest problem.

Water delivery support

Use live status to coordinate delivery timing while there is still room to plan.
