Residential meter ( P1 Port Only)
Our EMS can read the Belgian digital meter installed by Fluvius through its P1 port. This is the user port available on residential digital meters, exposing real-time consumption and injection data.
A P1 reader connected to this port forwards the meter data to our EMS, where it is used as a measurement reference.
Caution
Crucial: Activate the P1 Port first! By default, the User Port (P1) on the digital meter is closed. The Controller cannot detect the meter if the port is not active.
Log in to mijn.fluvius.be.
Go to Producten & Diensten > Verbruik > Beheer poorten.
Enable the P1 port.
Check the display on the meter: A small triangle arrow (▼) must be visible above the text "P1". If this arrow is missing, the port is dead.
Connection
1. Wiring
Connect the Digital Meter to the Controller using a P1 Cable (USB to RJ12).
Locate the yellow rubber cover labeled P1 on the right side of the meter.
Plug the RJ12 connector into the P1 port.
Plug the USB connector into the Controller.
Warning
P1 vs S1 Do not use the S1 port (often an RJ45 port on top). This is for the grid operator only. You must use the P1 user port on the side.
Troubleshooting
Meter not found
P1 Port inactive: Check the Fluvius portal. Is the arrow (▼) visible above "P1" on the LCD display?
Meter not found
Wrong Port: Ensure the cable is in the P1 port (RJ12), not the S1 port.
Meter not found
Cable issue: Use a verified P1 cable. Standard telephone cables often do not work because the signal lines are inverted.
EMS functionality
With the current integration, our EMS enables:
Real-time monitoring of grid consumption and injection
Use of the meter as a reference point for control strategies such as self-consumption optimization and capacity management
For larger installations measured on the A1 port, see Industrial meter (A1 Port Only).
