Hello,
i want to use a EM24 Ethernet to measure the current in 3-phase AC-system.
Can the EM24 measure both directions? ... Becasue in the datasheet the minimum current value is 0A. But the type of transmitted field in a integer with both positiv and negative values.
What's correct?

I have an EM24 set up as a grid meter in multiphase.
I am interested in power values and directions, but this may apply to currents as well.
I found that in VRM, the remote console only reported forward energy. I couldn't see my exports.
However, on the VRM dashboard, the "live" power (kW) was reported both forward and reverse.
I wanted to see reverse energy (kWh) though.
The per-phase values are available through the new Beta custom widget. Unfortunately, the total energy forward and reverse (although available to select) do not work yet.
The way I was able to see these values was by installing the Venus large operating system with node-red and creating a Dashboard.
This gave me a dashboard like this:
I am no Node-Red whizzkid, I just fumbled through it. These are the default format of values and this is an auto-generated dashboard and I don't even know how to manipulate either.
I hope this helps.
PS. If someone knows how to truncate a value in Node-Red, I'd be grateful.
