Energy usage monitors / meters for residential 3phase

[SonOne]

Hello all,

I am looking for recommendations / opinions on energy usage meters / monitors for use with my 3-phase power set up at home. Planning to install solar to add to my existing generator in the next 3 months and interested to gather some data before I do that. I have a Hexing HXE34 out in the street and a Hexing CIU-EV-KP in the house; the CIU shows the consumption details but nothing I can read off and track (not even the blinking LED that some smart meters have, which could be read electronically for this purpose). The current config is set up for pre-paid billing.

Anyone know of some cost-effective options out there for this use case?

Thank you.
