Out of sight.Shouldn’t meanout of salt.

Your softener depends on salt you can’t see. When it runs out, hard water quietly comes back into your pipes, fixtures and appliances, usually weeks before anyone thinks to check.

Lifting the lidPeeking in with a flashlightSticky-note remindersFinding out in the shower

It looks down,so you don’t have to.

Every six hours, a time-of-flight laser measures the distance down to your salt, then SaltMate goes back to sleep to save its batteries. The app does the rest.

  1. Measure 438 mm

    Distance from the lid to the top of the salt.

  2. Convert 68% full

    Worked out from your tank’s depth, set once during setup.

  3. Forecast ≈ 4 weeks

    Estimated from your recent readings, once there’s enough history.

  4. Alert Salt is getting low

    A push notification at the level you choose. Press the button any time for a fresh reading.

Your water softener’s missing gauge.

Your car warns you about fuel. Your softener never warned you about salt. Here’s one tank, six weeks, with SaltMate watching.

Day 1

Fill the tank, then forget about it.

That’s the whole idea. SaltMate hangs under the lid and keeps the watch you used to keep.

Salt level first. Everything else, a tap away.

Open the app for the level, a run-out date, and how the monitor itself is doing. Or check the web dashboard from any browser.

  • A run-out date, not just a percentageIt gets more precise as more readings come in.
  • Honest about itselfBattery, WiFi, sensor health and a timestamp on every reading. Old data looks old.

It works out how fast your home uses salt.

As readings build up, the app calculates your average daily use, and the guess becomes a date.

SaltMate app: Salt tank at 47 percent and Good, runs out in about 5 weeks, measured 6 minutes ago

A heads-up, with time to spare.

At the level you choose, your phone gets a nudge. Pick up salt on your next grocery run, not in an emergency.

When you refill, it notices.

Press the button for a fresh reading, or wait for the next one. The refill lands in your history automatically, with 30-day, 6-month and year views.

SaltMate app History: the salt level over 30 days, with the refill marked, average use of 1.3 percent a day and 2.2 bags used

Made to disappear under the lid.

  1. 109.2 × 33.4 mm

    Low enough to vanish.

    A slim puck that tucks under most brine-tank lids, with nothing to plug in.

  2. Time-of-flight laser

    It looks straight down.

    Every six hours the laser measures the distance to your salt, then SaltMate goes back to sleep.

  3. Button + status light

    A fresh reading, on demand.

    Press the button any time for a new reading. The light shows you it’s working.

  4. Twist-lock plate

    Twist on. Twist off.

    The plate stays stuck to your lid. A short twist takes the monitor off to swap its three AA batteries.

Set up in four steps.

  1. The round back plate stuck to the underside of a softener lid

    Stick the bracket in the lid

    Connect in the app

    The app joins it to your home’s 2.4 GHz WiFi. Blue means online, green means ready.

    Twist it in, close the tank

    Tap Start calibration for the first reading, then tell the app your tank’s size. Done.

Fit & install

Check these three things before you order.

  • A flat mounting areaRoom inside the lid for the 109.2 mm-wide monitor and its 33.4 mm body height, plus the raised button.
  • WiFi where your tank isA 2.4 GHz network with internet access, to sync readings and send alerts.
  • Above the salt and waterAn unobstructed view down to the salt, protected from splashes. The enclosure is not waterproof.

Will SaltMate fit my water softener?

SaltMate mounts to a flat area inside the brine-tank lid, with an unobstructed view of the salt below. The enclosure is 109.2 mm across and 33.4 mm high, with a slightly raised button. Check for mounting clearance and a usable 2.4 GHz WiFi signal at the tank before purchasing.

What does setup require?

You need a compatible brine-tank lid, the SaltMate mobile app, and an internet-connected 2.4 GHz WiFi network. The three AA alkaline batteries it runs on are in the box. During setup, your phone joins a temporary SaltMate WiFi network so the app can pass your home network details to the monitor. No separate hub is required.

Measuring & power

How does it measure the salt?

An integrated time-of-flight laser sensor measures the distance to the salt surface. The app combines that distance with your configured tank depth to calculate a fill percentage. An uneven salt surface or an obstruction can affect the reading; it is not a measurement of salt weight or water hardness.

Is the reading live all the time?

SaltMate sleeps between scheduled readings to conserve battery power. The default is one reading every six hours, and the interval is adjustable in settings. Press the monitor’s button for a fresh reading sooner. The app always shows when the last reading was taken.

Which batteries does it use?

Three replaceable AA alkaline batteries. Battery life depends on your reading schedule, WiFi conditions, and usage. SaltMate does not recharge the batteries. The app shows battery status and supports a battery-replacement push alert.

App & alerts

How do alerts and forecasts work?

Choose your low-salt level in the app and turn on notifications; your phone gets a nudge when the salt reaches it. SaltMate can also warn you about a week before the forecast run-out date, when the monitor stops checking in, when the level hasn’t moved for days (often a salt bridge), and when the batteries need replacing. Alerts depend on a successful reading, an internet connection and notification permission. Run-out dates and salt-cost estimates appear once enough readings are collected; they are estimates, not guaranteed dates or costs.

Which phones does the app work on?

The free SaltMate app runs on iPhone and iPad with iOS 15.6 or later (the home-screen widget needs iOS 16) and on Android 7.0 or later. Setup and phone notifications use the app; readings can also be checked in any browser on the web dashboard.

Can I check it on my computer?

Yes. Sign in to the web dashboard with the same SaltMate account to see your linked devices and their latest readings. Use the mobile app for initial WiFi setup and phone notifications.
