Energy use and power quality. In one view.
Look beyond the energy total. PEM431 brings true-RMS measurements, bidirectional energy data and harmonic analysis to a panel-mounted meter with LoRaWAN connectivity, two programmable inputs and two outputs.
YOBIIQ / PEM431See 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.
A monthly total does not show when consumption happens or how the building behaves outside working hours.
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.
Manual meter rounds take time, especially when the person reviewing the data works at another site.
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.
An energy total alone cannot explain the electrical conditions around equipment problems.
Use harmonic, unbalance and electrical measurements to prepare a closer on-site investigation. Relate measurements to equipment changes and operating times.
Turn a reading into a specific follow-up for the responsible person.
Explore how this device fits into a connected environment.
Look beyond the energy total. PEM431 brings true-RMS measurements, bidirectional energy data and harmonic analysis to a panel-mounted meter with LoRaWAN connectivity, two programmable inputs and two outputs.
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.
Measurement happens at the device. The chosen connection carries the information to the application, where your team reviews it and defines follow-up.
Install the PEM431 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.
Register the device on a suitable LoRaWAN network and configure the matching payload handling. Check timestamps and units in the receiving application.
Confirm that the dashboard reading agrees with the commissioned measurement point.
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.
Connect the device to a LoRaWAN network, then bring its data into the application your team uses. Each layer has a different job.
Connect devices and route their LoRaWAN messages.
Turn decoded data into dashboards, history and actions.
Network and application integration must use the payload for the supplied hardware and firmware. Tell us your network server and platform so we can confirm the integration details.

These details describe PEM431. Select the matching current transformers and verify the supplied configuration using its datasheet.
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.
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.
