This is my current setup.
I have a SMA Tripower 5.0 inverter with Webconnect, connected with a Ethernet cable to my network.
Then I have a Raspberry Pi Running SBFspot, transmitting my SMA data to PVOutput every 5 minutes.
This works Great.
But I also want to measure my consumption now.
I live in Belgium and I don’t have a smart meter from the electricity company yet, who can do it for you.
Still have the old analog meter, and intend too keep it as long as possible (Belgian people will know why).
So I need a way to measure my consumption with an external meter.
I have an ‘old’ Smappee laying around, but its not able to measure my PV pannels, only the energy I take from the supplier.
I hooked it on to see what happens and during the day it reports my consumption minus the power my pannels are generating, so that’s not good.
The tricky part is that my electricity cable coming in from the company is a 3-phase cable, and my inverter is also a 3 phase inverter.
So if I would go the smappee-like way, I would need 6 clamps to be able to configure it correctly, correct me if I’m wrong.
Have not found anything like that online.
I could just buy a SMA home manager 2.0, which I think would solve my problem but it too expensive (600 - 700 euro’s).
What would be the best and most inexpensive way to go here?
Help would be much appreciated as I’ve spend many hours online looking for a inexpensive solution to this.
