under the lid.

A low-profile enclosure keeps the sensor pointed at the salt. The four-point twist-lock mount lets you remove the monitor for a battery change without peeling the plate off your lid.

BEFORE YOU BUY

A quick check
for your tank.

Make sure there’s a clear home for SaltMate inside your brine-tank lid.

  • A flat mounting area

    Allow room for the 109.2 mm-wide monitor and its 33.4 mm body height, plus the raised button.

  • WiFi where your tank is

    A 2.4 GHz network with internet access is needed to sync readings and send alerts.

  • Above the salt and water

    Keep the sensor’s view unobstructed and protect it from splashes. The enclosure is not waterproof.

GOOD QUESTIONS

A little more
peace of mind.

What to know about fit, readings, batteries, and getting connected.

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.
