Water tank monitoring
Know exactly how much water you have.
A sensor in your tank and an app on your phone. See your level from anywhere, and get told the moment something is wrong — before you run dry.
Built by hand in South Kona, Hawaiʻi
See your level from anywhere
Percent, gallons and depth, updated continuously. Works on your phone, tablet or computer — nothing to install.
Catch leaks early
A slow drip can empty a tank over a week. SoKo watches overnight, when nobody is using water, and tells you when the level falls on its own.
Get told before you run out
Set your own thresholds and hear about them by text, email or push notification. Quiet hours built in, so a low tank never wakes you at 3am.
How it works
Installs in an afternoon.
No plumbing to cut and no trenching. The sensor hangs in the tank, the unit mounts on the wall, and it finds your Wi‑Fi from your phone.
Hang the sensor
A sealed pressure sensor drops through the tank lid and rests near the bottom. Nothing is cut, drilled or tapped.
Mount the unit
The enclosure mounts near the tank on standard power. The sensor cable runs back to it.
Connect and calibrate
Join it to your Wi‑Fi from your phone, tell it your tank’s size, and it starts reporting. Guided the whole way.
Alerts
It tells you when something changes.
Every alert is yours to turn on or off, with your own thresholds. Choose text, email, push — or all three.
Low and critical
At the levels you choose.
Tank full
Know when a fill or a good rain tops you off.
Rapid loss
A burst line or a valve left open, caught in minutes.
Slow leak
Found overnight, across quiet hours with no water use.
Away mode
Tighter watch while the property is empty.
Sensor offline
If the unit stops reporting, you hear about it.
