Growatt Solar Inverter Integration & Device Handler

Is anyone able and willing to write a device handler for Growatt Solar Inverters?

They are cloud connected, with a dashboard accessible at server.growatt.com and also an API published here: https://growatt.pl/wp-content/uploads/2020/01/Growatt-Server-API-Guide.pdf

I’m mainly interested in the current and Today power numbers so I can use them in automations. Section 4.2.5 of the API

There is something similar on Github here, but it’s python and I have no idea how to code.
