We qualify the hardware
Sourced, tested and known. We have run these devices in the field, so the surprises have already happened to us rather than to your customers.
Hardware we know,
badged as yours.
Devices we have already qualified, finished in your branding and wired into our platform. Your customers see your product, your name and your dashboard — not a rebadged box with someone else's logo in the corner.
How it works
Three things happen to every unit
We start from hardware that already works, so you are not paying for a design cycle you do not need — then we make it yours and put a platform behind it.
We make it yours
Your branding on the housing, your name in the interface, your domain on the dashboard. Custom firmware and software for whatever the device has to do that it cannot do stock.
We put a platform behind it
Provisioned before it ships, reporting into our IoT core or into your own cloud, with the dashboards and API your customers actually log into.
How they fit together
three typical sites
Every unit here is chosen to work with the others. Solid lines are wires, dashed lines are radio, the dotted box is the building, and the platform is always on the right. Each product page shows the same diagram with that unit lit.
reference deployment 01 · wifi-site
Wi-Fi metered building
One distribution board, three circuits, no usable network on site. Each circuit gets an IEMTR-EM165-W on a 100 A CT; all three join the Wi-Fi of an IESG-R250, which carries the readings out over 4G. The site provides a socket and nothing else. Put an IEMTR-EM4423-W on the incomer to see the total alongside the parts.

reference deployment 02 · mixed-site
Mixed site with outbuildings
A main building and several outbuildings across a yard. An IESG-R256 in the main building is the hub: an IEMTR-EM4423-W on the incomer joins its Wi-Fi, and an IESG-M52 on its Ethernet port listens for three IEMTR-EM165-L in the outbuildings over LoRaWAN. Two SIMs on the way out, so one network's bad day does not lose yours.

reference deployment 03 · rs485
RS485 retrofit
A plant room with equipment that already measures but never reports: a Modbus meter, a battery system on CAN. An IEMTR-WST-CAN-RS485 sits on both buses as one more listener and forwards the registers over Wi-Fi through an IESG-R250. Nothing is replaced. Swap in the relay variant to switch something as well.

site gateway · 4g router
IESG-R250
A 4G router, on-site Wi-Fi and a secure cloud gateway in one unit. Brings a site online and carries everything on it back to the platform.

site gateway · dual sim · rs485
IESG-R256
The site gateway with two SIMs and an RS485 port. Fails over between networks on its own and reads Modbus equipment directly, with no bridge in between.
view specification
lorawan gateway
IESG-M52
An eight-channel LoRaWAN gateway on Ethernet or Wi-Fi, PoE powered. Receives every LoRaWAN meter on the site and forwards it to the platform.
view specification
lorawan gateway · 4g
IESG-M52-4G
The same gateway with an LTE modem and a SIM slot. A complete LoRaWAN metering system that needs nothing from the site but power.

outdoor kit · lorawan gateway
IESG-M52-ODK
IP66 enclosure, pole and wall mounting, external antenna and one PoE cable, so the gateway goes outside where the range is.

and others we do not list publicly
single-phase energy meter · wi-fi
IEMTR-EM165-W
Single-phase, single-channel, one DIN module. Class B accurate and reporting over Wi-Fi, so a circuit can be metered without a cable run.
view specification
single-phase energy meter · lorawan
IEMTR-EM165-L
The same one-module meter over LoRaWAN. Reports through a gateway from outbuildings, basements and plant rooms that Wi-Fi never reaches.
view specification
three-phase energy meter · wi-fi
IEMTR-EM4423-W
Three-phase, on split-core CTs or Rogowski coils to 3000 A, with power quality to the 41st harmonic. The meter for the incomer, over Wi-Fi.

three-phase energy meter · lorawan
IEMTR-EM4423-L
The three-phase meter over LoRaWAN, for incomers and three-phase plant on sites with no network at all.
view specification
two-channel energy meter
IEMTR-2CH-CT100
Two circuits from one DIN-mounted unit, each on its own 100 A clamp. Bidirectional, so a solar feed and a load can be read on the same board.

rs485 · can bus bridge
IEMTR-WST-CAN-RS485
Isolated RS485 and CAN onto the network over Wi-Fi, on a 7–36 V input that runs from whatever is already in the cabinet.

rs485 bridge · relay output
IEMTR-WST-RLY-RS485
Isolated RS485 in, one 10 A relay out, both driven from the platform — so a reading can trigger an action with nobody on site.

Not sure which one fits?
Tell us what has to be measured, where it sits and what it has to talk to. If one of these is right we will say so; if none of them are, we will tell you that too and quote for the one that is.
