Can a ET340 be installed and directly connected to EV Charger NS through RS485?

Hello,

I have bought a EV Charging station NS and know now that it has no internal consumption metering. I saw on this community that some has variable settings (through node-red) for power calibration for different load amperage to get the most accurate power reading in VRM. Even with setting the power calibration as good as possible i see variation on the VRM when the voltage on the grid changes.

I was wondering if it is possible to put an ET340 inside the Charging Station (enough space available) and connect it to somehow the motherboard ? There are 4-pin connectors unused. Basically upgrading it with an internal consumption meter

I have a GX device running here, the EV Charger is part of the system (3x 48/5000VA).

Can not insert a snapshot of my VRM portal to show.

Is it possible when a GX device is present?
