Three self-powered sensors. One platform.
HotDrop measures amperage. VoltDrop measures voltage, current, and power factor. PulseDrop counts pulses from gas, water, and BTU meters. All three ride the same LoRaWAN network into CloudVU.

Sensor 01 · HotDrop
HotDrop
The self-powered amperage clip.
HotDrop snaps over a live conductor and starts reporting amperage in under a minute. A split-core current transformer measures the current; the device harvests its own power from the conductor it sits on. No batteries to swap. No panel downtime to schedule.
Key specs

Install
Snaps onto a conductor in seconds without taking the panel offline. Streams to CloudVU within minutes of clip-on.
Compatibility. Service-entrance feeders, sub-panel branch circuits, motor and chiller circuits, datacenter PDUs, tower AC feeds. Six conductor sizes cover most commercial breakers and feeders up to 4000A XL.

Sensor 02 · VoltDrop
VoltDrop
Revenue-grade polyphase metering.
VoltDrop is a self-powered polyphase meter for true RMS voltage, current, power factor, and real + apparent energy across single- and three-phase services. Choose a 24″ Rogowski coil, 8″ Rogowski, or 300A CT head to match the conductor. Mounts at the service entrance or branch panel without taking power down.
Key specs
- Measures
- V · A · PF · kWh · apparent kVAh
- Voltage range
- 85–305 VAC
- Current range
- Up to 4000A via coil/CT
- Phases
- Single-phase & 3-phase (Wye/Delta)
- Accuracy

- Power
- Self-powered (energy harvesting)
Install
Voltage taps to the service phases; coil or CT wraps the conductor. Same self-powered, no-panel-down workflow as HotDrop.
Compatibility. Single-phase 120/240V services, 3-phase 208/480V services, polyphase service entrances, large motor loads. Coil options: 24″ Rogowski for service entrances, 8″ Rogowski for branch panels, 300A CT head for fixed installs.

Sensor 03 · PulseDrop
PulseDrop
Pulse counting for everything that isn't already on LoRaWAN.
PulseDrop counts pulses from dry-contact and contact-closure outputs on legacy gas, water, electric, and BTU meters. IP67 for outdoor and weather-exposed installs. 10-year battery life. Drops a wireless tail on every existing meter in the building without rip-and-replace.

- Power
- 10-year battery (typical)
Install
Two-wire connection to the meter's pulse output. Mounts on the meter, in the meter cabinet, or on a pedestal — indoor or outdoor.
Compatibility. Any utility meter with a dry-contact / KYZ / Form-C pulse output. Common in gas meters (turbine, diaphragm), water meters (positive-displacement, electromagnetic), BTU meters, and legacy electric meters where the kWh pulse is the only digital signal available.
