SaltMate
Controlled beta in development

Never lift the lid just to check.

SaltMate watches your water-softener salt level and tells you when to refill—before hard water catches you by surprise.

Designed for iOS and Android

Laser measured Battery powered Low-salt alerts History & predictions

The least convenient place to check is the place you have to keep checking.

A brine tank gives you no warning. You remember it exists, find the lid, lift it, and peer into the dark—or find out after the softener stops doing its job.

SaltMate turns that hidden level into one clear reading on your phone.

Install it once.
Check from anywhere.

The monitor lives under the tank lid and quietly handles the rest.

  1. 01

    Mount under the lid

    The compact sensor puck points down at the salt surface—no cables into the tank.

  2. 02

    Laser-measure the level

    A time-of-flight sensor takes an honest distance reading every six hours by default.

  3. 03

    Know before it runs low

    See the level, forecast the empty date, and get a push alert at your chosen threshold.

THE RANGEFINDER

One glance.
One true reading.

The actual SaltMate app is designed like an instrument, not a dashboard. The current salt level owns the screen. Every reading carries a timestamp, and stale data looks stale.

  • Live device statusBattery, WiFi, and sensor health stay readable at a glance.
  • Useful predictionsSee when the tank may empty and what salt use costs over time.
  • History that adaptsWeek, month, and year views update when you recalibrate the tank.

THE MONITOR

Built to disappear under the lid.

A battery-powered ESP32-C3 and laser distance sensor live inside a compact round enclosure. SaltMate wakes, measures, uploads, and goes back to sleep.

18min

Honest freshness

Every reading is timestamped. If the monitor misses a wake, the app never pretends the data is live.

OK

Status beyond colour

Clear labels and icons back up every status colour, so the message never depends on hue alone.

⌁

Hardware-honest

Settings that need the sleeping monitor to wake say so plainly instead of promising an instant change.

PRE-SALE STATUS

SaltMate is getting ready for real tanks.

The product is in pre-sale hardening, preparing for a small controlled beta with known users. Hardware, setup, alerts, and long-term reliability are being tested before a wider release.
