Support for external energy meter possible?

[bouwew]

Describe the feature
I was wondering if it was possible to send data from an existing energy sensor present in HA to my SolarEdge inverter.
I did some deep browsing and finally ended up here: https://github.com/marcelrv/solaredge_meterproxy
@WillCodeForCats does this github contain anything useful that would help in realizing the requested feature?

I'm not expecting you to add this feature, I'm just wondering if there's anything useful in this github that could point the way for someone that has the background knowledge and some interest in adding this feature 🙂

The origin of my find is this blog post (sorry it's in Dutch): https://zonnigbreda.blogspot.com/2022/05/p1-port-als-energiemeter-voor-solaredge.html

If you connect a solaredge inverter to that integration it will appear as a meter in this integration.

This integration doesn't directly read meters, it reads the inverter. The inverter is providing the meter data as a proxy to whatever actual meter is connected to the inverter's RS485 bus.
