The Knode node: a rugged black weatherproof enclosure with cable glands and an antenna connector
The system

Simple hardware. Smart system.

Rugged sensors you fit yourself, 4G cellular that reaches the back paddock, and a platform that turns every reading into something you can act on.

How it fits together

From the water to your phone.

  1. 01SensorsMeasure tank levels, flow, pressure and pump activity where the water is.
  2. 02NodeCollects readings from the sensors at each point and sends them on.
  3. 03NetworkThe NZ 4G cellular network carries it off the property. No Wi-Fi needed.
  4. 04Knode platformStores every reading, spots what's unusual and works out your daily use.
  5. 05YouLive dashboards on desktop and phone, and alerts by text and email.
The hardware

Built for the paddock. Fitted by you.

Every point on your map gets one Node v3, plus the sensors that point needs. Pump control units connect on their own. It all arrives pre-configured, with a 2-year hardware warranty.

Node v3

The heart of each monitoring point. Connects up to 2 tank or pressure sensors and 3 flow meter connectors, and sends their readings to the platform. Comes in two versions at the same price: solar for remote sites, or mains power for a shed or pump house.

Solar node
Solar panel and backup battery: runs 8–12 weeks with no sun
Power node
Plugs into a standard wall outlet. Backup battery keeps it reporting through a power cut, and it alerts you when the mains goes off
Enclosure
IP67, UV-stable
Connectivity
4G LTE-M and NB-IoT on the NZ cellular network
Reporting
Every 15 minutes
Mounting
On the tank or a post

Tank level sensor

A submersible pressure sensor that sits at the bottom of the tank and measures the water level, so you see percentage full, litres and depth. Insects and debris can't interfere with it.

Measures
Level, volume, % full
Depth
3 m standard, 5 m option
Fitting
Dropped in through the top of the tank (its own drilled hole, or through the lid)
Use in
Concrete, plastic and steel tanks; ponds, dams and reservoirs; bores and wells
Cable
Standard length, extendable
Per node
Up to 2 (shared with pressure sensors)

Flow meter connector

Connects to the flow meter on your supply or distribution line to track flow rate and daily use, and flags water moving when it shouldn't be. The flow meter itself isn't included.

Measures
Flow rate (L/min), daily volume
Compatible meters
Any pulse-output flow meter (litres per pulse set at setup)
Flow meter
Not included. No meter yet? We'll recommend one
Fitting
Wired pulse cable, extendable
Per node
Up to 3

Pressure sensor

Measures line pressure on your water supply, so you can see a pump struggling, a blocked filter or a burst pipe as it happens.

Measures
Line pressure, 0–10 bar
Per node
Up to 2 (shared with tank sensors)

Pump control unit

Wired into your pump's control circuit so you can start and stop it from the app, run it on a schedule, or let it run itself: start when your tanks drop, stop when they're full. It confirms every command and tells you if the pump trips on low water. It can also open and close motorised valves.

Controls
Remote start/stop, schedules, automatic on tank levels, motorised valves
Reports
Running status, low-water cut-out, command confirmed
Connectivity
Its own 4G connection: no Knode node needed
Fitting
Needs an electrician to wire it in (you arrange this)
Plan
Counts as 2 assets

Irrigation control

Run solenoid valves on a schedule or on demand from the app, and see every run as it happens. Every irrigation setup is different, so we design it with you.

Controls
Solenoid valves, schedules, manual runs

Connectivity

Reaches the back paddock.

Every node connects straight to the NZ cellular network using LTE-M and NB-IoT, the 4G technologies built for low-power sensors spread across big properties. There's no Wi-Fi to extend, no gateway to install and no cables to run between paddocks.

Before anything is ordered, we check coverage for each point on your map, so you know it will connect before it arrives.

The platform

Every reading, working for you.

Our cloud platform has been refined since 2017. Log in from your desk or your phone to see what's happening, and let it tell you when something needs attention.

Live dashboard

Every tank and pipeline at a glance, in a list or on a map of your property.

Alerts you set

Low levels, unusual flow, or a pump that trips or goes offline. By text and email, to whoever needs to know.

History and trends

Levels, volume and daily ranges over days, weeks or seasons.

Water-use reporting

Show responsible use and the value it creates, whenever you need it.

Pump control

Start and stop pumps from your phone, set schedules, or let them run themselves off your tank levels.

Your team, every property

Give managers and staff their own access and alerts, across every farm or site, from one login.

See what your property needs.

Map your tanks, lines and pumps, see your price, and we'll call you back. No commitment.
