Customisable kits. This is one of the Milesight LoRaWAN kits in the Smart Home section. For different installations, custom kits or bespoke automations, write to us from the contacts section.
Several sizes. The figures, diagram and table on this page describe the «16 circuits + main incomer» size. The other sizes are selected above and are listed further down, under «Available sizes».
12 single clampsFour up to 100 A and eight up to 250 A, one per phase conductor, with a 16 mm opening.
2 three-phase meters up to 500 AThree clamps each, with a 36.5 mm opening, for the largest outgoing circuits.
Main incomer up to 1,000 AOne three-clamp meter with a 51 mm opening on the panel incomer.
No batteriesThe meters are powered by the current they measure; alternatively from USB-C at 5 V.
What it does
- Each meter reads the RMS current of its own circuit, with 1% accuracy above 5 A, and sends it by radio to the gateway mounted in the panel. The transmission interval is 10 minutes and can be set from 1 minute to 24 hours.
- Besides the instantaneous value, the meters totalise ampere-hours. By setting the voltage and cosφ of the circuit they also calculate energy in kWh: this is an estimate suitable for allocating consumption between departments and cost centres, not a billing-grade measurement.
- The three-clamp meters read the three phases at the same moment: you see the imbalance between phases and, on the main incomer, the comparison between total draw and the sum of the outgoing circuits.
- Current thresholds are set for each circuit: the notification arrives when a load draws more than expected, when a circuit stays under load while the plant is idle, or when a circuit that should be running stops.
- The three-phase meters come with a temperature probe on a 1 m cable, to be fixed onto a cable to keep its heating under control.
- Load profiles, history and notifications can be consulted from a smartphone and from a PC: a data base for the energy audit and for a management system to ISO 50001.
For a different number of circuits, several panels or sub-panels in distant departments, ratings other than those provided for, or if there is no internet connection in the panel room and a 4G gateway is needed: tell us the characteristics of your panel from the contacts section and we will propose the right configuration with a quotation.

How it is installed
Gateway. On a 35 mm DIN rail or on the wall, inside the panel or in a small enclosure next to it. It is a panel device: IP30, operation from -20 to +60 °C. Powered by USB-C at 5 V with the supplied power adapter, or by PoE from the switch; connection to the company network with an Ethernet cable or Wi-Fi. The magnetic-base antenna must be brought outside the metal enclosure and stood vertically on a metal surface, for example the top of the panel, high up and away from walls and obstacles.
Single clamps on the small and medium circuits. You open the clamp and close it again around a single phase conductor, until it clicks. Never phase and neutral in the same clamp: on a multicore cable the clamp goes on the individual conductor, in the section already stripped downstream of the breaker. The opening is 16 mm on both models. The meter hangs from the conductor or is held with a cable tie. To power itself it requires a minimum current of 1.5 A on the 100 A model and of 3 A on the 250 A one.
Three-phase meters on the large outgoing circuits. Three clamps with a 36.5 mm opening, one for each phase, connected to the transmitter with 1 m cables. The phase A clamp must always be fitted, because it is the one that powers the device. The transmitter is small and light: it is fixed with a cable tie at a convenient point on the trunking or the upright. Minimum current 5 A. The three clamps can also measure three separate single-phase circuits.
Main incomer and low-load circuits. On the panel incomer the three clamps with a 51 mm opening are fitted, one per phase; minimum current 10 A. On circuits that stay idle for a long time or below the minimum current the meter is powered from a USB-C 5 V power adapter; without external power it keeps working anyway for about 12 hours after the current has stopped. Apply the numbered labels to circuits and meters while fitting them.
Configuration. The meters are configured from a PC with a USB-C cable and the manufacturer's free software, not by NFC: transmission interval, alarm thresholds, voltage and cosφ for the kWh calculation, name of the circuit. It is best done on the bench, before going into the panel. The gateway is configured from a browser. No paid software is needed.
Documentation included. A written installation guide with the pairing between meters and circuits, the position of the clamps, the placement of the antenna outside the panel and the switch-on sequence, plus initial configuration of thresholds and energy calculation parameters based on the list of circuits given when ordering.

Before you order
Do you have to switch off the power to fit the meters?
No. The clamps are split-core and close around the conductor without disconnecting it: there are no terminals to open and no circuits to interrupt. The work does however take place inside a live panel: it must be entrusted to an electrician qualified for this kind of job, following the safety procedures of the plant.
Is an internet connection needed in the panel room?
It is needed at the point where the gateway is fitted: a network socket or the coverage of the company Wi-Fi. The meters do not use Wi-Fi, they talk to the gateway by radio. If the network does not reach the panel room, the version with a 4G gateway is available, which requires a data SIM (not included, any operator, traffic below 1 GB a month). It is selected when ordering.
Does the radio signal get out of a metal panel?
The metal enclosure attenuates the signal: this is why the gateway antenna is brought outside, with the magnetic base resting on the top of the panel. With the meters in the same panel, or in panels in the same room, the distance is a few metres. For the DIN-rail gateway the manufacturer states up to 2 km in urban areas and 15 km in open country; inside a plant the range depends on walls, floors and metal structures. For sub-panels in distant departments a second gateway is considered. One gateway handles hundreds of devices.
Do they measure energy or only current?
They measure current, with 1% accuracy above 5 A, and totalise ampere-hours. The kWh are calculated by the meter from the voltage and the cosφ that you set for each circuit: the figure is suitable for the internal allocation of consumption and for comparing periods, it does not replace a billing meter or a power analyser.
How are the meters distributed over 16 circuits?
Each single clamp measures one conductor: a single-phase circuit, or one phase of a balanced three-phase circuit such as a motor. Each three-clamp meter reads a complete three-phase circuit or three single-phase circuits. A typical split is: 12 circuits on the single clamps, one large three-phase outgoing circuit on the first 500 A meter, three single-phase circuits or a second three-phase outgoing circuit on the second, the main incomer on the 1,000 A meter. If many circuits are unbalanced three-phase, three clamps per circuit are needed: tell us before ordering.
What happens on circuits with little load or often idle?
The meters draw their power from the current flowing in the conductor and require a minimum of 1.5 A (100 A model), 3 A (250 A), 5 A (500 A) and 10 A (1,000 A). When the current stops they keep working for about 12 hours. On circuits that stay idle for longer, or that work below the minimum, a USB-C 5 V power adapter is connected.
I have more circuits or more than one panel
The kit is configured around the panel: meters of the required rating are added, gateway and platform stay the same. Among the product options you will find the 24 and 32 circuit sizes; for different situations write to us from the contacts section giving the number of circuits, the breaker ratings, which circuits are three-phase and how many panels: we will send you the make-up and the quotation for the adapted kit.
Will the conductors of my panel fit through the clamps?
The opening is 16 mm on the 100 and 250 A models, 36.5 mm on the 500 A one and 51 mm on the 1,000 A one. It is worth checking the cable diameter in advance, especially on the main incomer. If the main incomer is made of busbars or exceeds 1,000 A, write to us from the contacts section before ordering.
Where is the data consulted and are there any fees?
On the manufacturer's app and portal, from a smartphone and a PC, with charts, thresholds and notifications; no fee for basic use. Where there is an energy monitoring system, a SCADA or a management system, the gateway can also send the data to that system (MQTT or HTTP): the configuration is included.
What happens if the internet is down?
The meters keep measuring and totalising the ampere-hours: when the line is restored the cumulative total resumes up to date, while the detail of the readings for the period without a connection may be incomplete. The system only reads: it does not act in any way on the breakers and protective devices of the panel.
