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.

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.

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.

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.
Open the web dashboard

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.

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.

Good questions.

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.

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.

What does setup require?

You need a compatible brine-tank lid, three AA alkaline batteries, the SaltMate mobile app, and an internet-connected 2.4 GHz WiFi network. 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.

How do alerts and forecasts work?

Choose your low-salt threshold in the app and enable phone notifications. Alerts depend on a successful sensor reading, an internet connection, and notification permission. Refill-date and salt-cost estimates appear after enough usage history is collected; they are estimates, not guaranteed dates or costs.

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.

Is it waterproof?

No. The sensor opening is not sealed, and the enclosure is not rated as waterproof or dust-tight. Keep SaltMate above the salt and water, protect it from splashes and submersion, and keep the optical opening clear.
