DEM4 / Energy Measurement
DEM4 — Three-phase energy meter
Measure the circuit. Understand the demand.
Bring three-phase circuits into the same operational view. DEM4 combines energy metering with two digital inputs and two outputs, with direct-connected and current-transformer variants for different panel arrangements.

IN YOUR ENVIRONMENTPRACTICAL USE CASES
A reading is the start of a better question.
See where electricity is used, put unusual patterns in context and give the people responsible a consistent view. These are example applications to plan around your site.
EXAMPLE APPLICATIONProperty managers
Property managersDiscuss a similar project
Understand a building’s baseline
A monthly total does not show when consumption happens or how the building behaves outside working hours.
WHERE YOBIIQ COMES IN
Include electricity measurement in the building overview. Compare the same periods and annotate opening hours, occupancy and maintenance before interpreting changes.
Give the team a baseline to compare before and after operational changes.
EXAMPLE APPLICATIONFacilities teams

Follow several locations
Manual meter rounds take time, especially when the person reviewing the data works at another site.
WHERE YOBIIQ COMES IN
Connect measurement points through the chosen network and name them by building and circuit. The application brings readings and history together for the team.
Review sites through one repeatable workflow, with fewer routine trips to collect readings.

Spot a change worth investigating
A change in consumption can go unnoticed when readings are reviewed only occasionally.
WHERE YOBIIQ COMES IN
Configure comparisons and notifications in the receiving application. Use the measured trend to decide what needs checking on site; a consumption change alone is not a diagnosis.
Turn a reading into a specific follow-up for the responsible person.
EXPLORE THE POSSIBILITIES02 / CONNECT THE DOTS
A closer look. A clearer picture.
Explore how this device fits into a connected environment.
Bring three-phase circuits into the same operational view. DEM4 combines energy metering with two digital inputs and two outputs, with direct-connected and current-transformer variants for different panel arrangements.
Your device communicates over LoRaWAN. A gateway forwards its messages to a network server, ready for your application to use.
Bring device information into a monitoring platform. Follow readings and events together, with a clearer picture of the environment you manage.
What the device does

- DIN-rail installation
- Modbus RTU or LoRaWAN variants
- Demand measurement
UNDERSTAND THE OPERATIONDEVICE + APPLICATION
See what happens.
Step by step.
Measurement happens at the device. The chosen connection carries the information to the application, where your team reviews it and defines follow-up.
MEASUREMENT Information / action
- DEM4Measurement point
- Local readingDevice measurement
01 / IN PRACTICE
Measure at the connection
Install the DEM4 at the selected measurement point and commission it against the supplied installation documentation. Check the local reading before relying on the remote view.
Record a known reading as the starting point for commissioning.
CONNECTIVITY Information / action
- DEM4Meter data
- LoRaWAN / Modbus RTUSelected connection
- ApplicationDecode and display
02 / IN PRACTICE
Connect the reading
Choose a LoRaWAN variant for wireless reporting or Modbus RTU for a wired installation. Configure the correct payload decoder or register mapping for the exact model.
Confirm that the dashboard reading agrees with the commissioned measurement point.
APPLICATION Information / action
- Readings over timeHistory and comparison
- Your teamReview and follow-up
03 / IN PRACTICE
Use the information
Build histories, comparisons and notifications in the application. Define who receives an exception and what happens next, rather than leaving the reading in an isolated dashboard.
Assign an unusual consumption pattern to the facilities team for investigation.
FITS INTO YOUR WORLDNETWORKS & PLATFORMS
Your network.
Your way of working.
Connect the device to a LoRaWAN network, then bring its data into the application your team uses. Each layer has a different job.
01
Network servers
Connect devices and route their LoRaWAN messages.
02
Application platforms
Turn decoded data into dashboards, history and actions.
LoRaWAN models use a gateway and network server; Modbus RTU models connect through a compatible wired integration. We match the selected model’s payload or registers to your platform during commissioning.

SPECIFY IT FOR YOUR PROJECT
Check your configuration Choose the phase arrangement, current range and communication option first. Specify a built-in relay only where required: a digital output is not the same as a load-switching relay. Match output ratings and CT details to the supplied model’s installation documentation.
FROM SELECTION TO SITEPLAN YOUR INSTALLATION
A good deployment starts here.
Four things to settle before the first device goes into service.
- 01
Define the measurement point
Identify the location, expected range and the question the measurement must answer.
- 02
Select the exact version
Choose the phase arrangement, current range and communication option first. Specify a built-in relay only where required: a digital output is not the same as a load-switching relay. Match output ratings and CT details to the supplied model’s installation documentation.
- 03
Commission the connection
Verify network coverage or bus wiring, device identity and payload or register mapping.
- 04
Check the complete chain
Compare a local reading with the receiving platform, confirm units and timestamps, and document the operating procedure.
QUESTIONS, ANSWERED
Before you choose.
Practical answers about DEM4 — Three-phase energy meter.
Ask us something elseWhat should I specify when ordering DEM4?
Choose the phase arrangement, current range and communication option first. Specify a built-in relay only where required: a digital output is not the same as a load-switching relay. Match output ratings and CT details to the supplied model’s installation documentation.
Can every version switch a load?
No. DEM2-80-1I1R includes a relay. The other listed configurations have outputs that must not be treated as an equivalent built-in load-switching relay. Match the electrical interface to the exact model documentation.
What is needed for a remote dashboard?
For LoRaWAN reporting, provide network coverage, device registration and a decoder matching the hardware and firmware. The application then handles storage, visualisation and any configured notifications.
Does monitoring automatically save resources?
It gives you evidence for decisions and a way to check their effect. Results depend on the changes made to the installation or operating routine.
