HotDrop™

Current monitoring that powers itself.

HotDrop™ is a wireless, self-powered current sensor. A split-core transformer clips onto a live conductor in under 15 minutes, harvests its own power from the line it measures, and streams revenue-grade amperage data over LoRaWAN — even from inside a metal panel.

Measures
Amperage, max/min amperage, and amp-hours
Power
Self-powered — harvests energy from the conductor, no batteries
Accuracy
Revenue-grade, ANSI C12.20 Class 0.5 (0.5%)
Voltage
Single- or multi-phase circuits up to 600V AC
Range
Six split-core sizes, from 300A to 4000A XL
Connectivity
LoRaWAN — transmits reliably from inside metal enclosures

Self-powered, non-contact monitoring

HotDrop™ uses a split-core current transformer to read the current flowing through a conductor, and it harvests its own power from that same line — so there are no batteries to replace and no parasitic draw on the panel. Clip multiple HotDrops onto a single panel for circuit-level visibility at scale.

1

Install HotDrop™

Clip the split-core sensor around the conductor and confirm it is latched closed. No de-energizing, no electrician.

2

Onboard to the network

Add the device to a LoRaWAN network in minutes using the Vutility app.

3

View real-time data

Watch live amperage and amp-hours in CloudVU from any phone or browser.

Built for the field

Installs in minutes

Clip-on, non-contact install with no facility downtime and no planned outage.

Accurate at scale

Minute-by-minute data across many circuits and panels in large commercial and industrial sites.

Six sizes

From 300A to 4000A XL to fit nearly any conductor.

Self-powered

No batteries, no charging cables — it runs on the energy it measures.

Wireless and resilient

LoRaWAN keeps data flowing even from inside steel enclosures.

Platform-ready

Streams straight into CloudVU or your own LoRaWAN network.
