mqtt Energy Meter for 600/5 CT

Can any one advise if there is a Energy Meter available that accepts the 5A secondary for larger CT ratios 600/5 that could publish real time kw out every 1 or 2 seconds in the form of an mqtt publish.

I would like to read this value into a Venus running Node Red which is 100m away from the Energy Meter.

You could try this way: https://community.victronenergy.com/questions/202259/em540-via-ethernet.html

I did exactly the same, works like a charm. I am getting crazy fast updates on the readings.

(This solution ticks all boxes, except for the mqtt part. But you don't need this when you have the readings in VenusOS/dbus)

additional info: I am running EM530 with 5a*60 CTs. You can always use different ratio-CTs with the EM530 as long they are 5a.
