I have similar plans but I plan to do it with an Easymeter Q3. That meter is supporting the EDL21 integration. Even though I could do this myself I will contract an electrician since I am renting the apartment and they probably want it done properly.
I have read in the docs the page “Integrating your solar panels” and after a bit of googling I found the following forum thread: Monitor your solar PV system in Home Assistant
My priority will be in the end that nothing of the software depends on any cloud integration.
Edit: Sadly my landlord didn’t allow me to mount the panels as such I won’t be able to execute the project.
