Priva & Nelson | Wireless Precision Irrigation Solutions

The Challenge

Good strategies, unreliable execution.

Most growers have experienced the frustration. An irrigation strategy is carefully planned, schedules are set, and then something goes wrong in the field. A valve sticks. A zone gets too much water while another gets too little. Fertilizer is applied at the wrong moment, when the plant cannot fully use it. By the time the problem shows up in the crop, the damage is done.

Water applied on schedule, not on demand

Fixed irrigation schedules don't respond to what the plant actually needs. Water and fertilizer go in whether the crop is ready for them or not.

No confirmation from the valve

Commands go out but there's no reliable way to know whether each valve opened or closed as intended. Problems go undetected until the crop shows it.

A gap between strategy and what crops receive

When irrigation strategy and field execution aren't connected, growers fill the gap with guesswork. That uncertainty is expensive, and it weighs on every decision.

Twig-V Hub

The network controller. Manages up to 100 Twig-V receivers plus 8 repeaters. Connects to Priva via ethernet. Fast-response 900 MHz line-of-sight radio.

Twig-V Remote Mount

Wires to any 12VDC latching solenoid or relay. Controls 1 or 2 devices. Internal or external antenna. Ideal for retrofitting existing valve infrastructure.

Twig-V Plus (On-Valve)

Fully self-contained. Integrated solenoid, solar panel, and rechargeable battery. No wiring, no power source required. Mounts directly on the valve.

Twig-V Repeater

Extends wireless coverage by creating sub-networks. Runs on 110 VAC or 12 VDC with external antenna. Up to 8 repeaters per hub network.

SE (Switch Enabled) Model

Connects to a pressure switch to confirm actual valve operation. Closes the feedback loop so Priva knows the valve opened, not just that the command was sent.

Bluetooth Setup

All Twig-V units configure via Bluetooth for fast, cable-free commissioning. Sealed enclosures protect electronics in field and greenhouse environments.

Greenhouse Operations

Connect Priva's full climate and irrigation control to wireless valve management across multiple compartments. Everything managed from one place, with confirmation that every zone received what it was supposed to.

Open Field & High Tunnel

Cover large and complex growing areas without the constraints of running cable to every valve. The Twig-V Plus solar model requires no power infrastructure at all, making it practical even in remote field locations.

Retrofits & Upgrades

Nelson's wireless receivers wire directly to existing solenoids, so growers can bring precision and feedback to their current valve setup without replacing hardware or starting from scratch.

Multi-Zone Consistency

Deliver the same irrigation strategy across every zone and know that it landed as intended. Real-time valve confirmation replaces assumption with a verifiable record growers can act on.

Give plants exactly what they need	Reduce input costs and labour
Irrigation triggered by actual crop demand, using real-time data on water uptake, substrate weight, and climate conditions	Meaningful reductions in water and fertilizer spend, accumulated over a full growing season of more precise application
Fertilizer applied at the right moment so the plant can fully use it, reducing loss to drainage and runoff	A verifiable record of every irrigation event, so growers can see what worked and keep refining their strategy
Consistent delivery across every zone, not just the zones a grower happens to check that day	Remote monitoring and control frees up labour and lets growers respond to issues before the crop feels them
