Tile and coping repairs from a single freeze typically run $3,000–$8,000. Pool Guardian's dual-sensor system keeps your water level safely below the tile line all winter — automatically, for $249.
When water sits at the tile line and freezes, it expands — cracking grout, popping tiles, and damaging coping. It happens overnight, while you're away, and it's entirely preventable.
Two sensors. One pump. No internet needed. Pool Guardian runs entirely on local hardware — no weather feeds, no cloud dependency, no manual intervention.
Set the low sensor below your tile line, high sensor a few inches above. The device clips to the pool coping — no drilling, no plumber.
The control box checks both sensors around the clock. No WiFi needed for protection — internet only required for optional remote monitoring.
High sensor trips the pump on. Low sensor turns it off. Water level stays below the tile line every time, automatically.
Takes about 15 minutes to install — no special tools, no electrician required.

Without Pool Guardian, keeping water below the tile line means checking the level yourself after every storm, every snowmelt, all winter long. Pool Guardian does it automatically.
Water rises after rain or snowmelt, sensors detect it, pump drains it. You don't check, you don't remember, you don't do anything.
Keeps water safely below the tile line all winter. Freezing water expands below the tile, not against it.
Paid plan sends push and email alerts when sensors trigger. Every drain event is timestamped and logged.
15 minutes, no special tools. Works with Home Assistant on the Free plan — no cloud account required.
Sensor protection runs entirely on-device — no internet needed. WiFi only required for optional cloud monitoring.
The Business plan lets service companies manage 50+ client pools from one dashboard — alert-based, not check-in-based.
Buying IoT hardware you've never heard of is a leap of faith. Here's exactly what you're protected by.

Real humans, real responses. Email or call us and you'll hear back within one business day — not a support ticket queue.
On the Paid plan, you'll get an alert the moment a sensor stops responding or the device goes offline — so your service company or a neighbor can check it before there's a problem. On the Free plan, a local alert is triggered on the app when you're on your home WiFi.
"Got an alert that the high sensor triggered at 2am. By the time I saw it, the app already showed the drain was complete. Never had to do a thing."
"I run Home Assistant for my whole house. Pool Guardian slotted right in on the Free local plan. Setup in 15 minutes, no cloud account needed. Exactly what I wanted."
"We installed on 60 client pools this fall. The fleet dashboard alone saved us dozens of unnecessary site visits. Our clients love the peace of mind too."
