Know your water level,
from anywhere.

Real-time tank monitoring for rural properties. Your plumber installs a small sensor, and you check your water level any time — from your phone or computer.

How it works

1. Your plumber installs the sensor

A small waterproof sensor mounts inside your tank. Connects to your home WiFi — no separate hub needed.

2. Readings sent every minute

The sensor measures water depth continuously and sends readings to the cloud over your WiFi connection.

3. Check from anywhere

Open the web app on any phone or computer. See current levels, usage trends, and 30 days of history.

Everything you need
