I have a Deye 5kW inverter and found this excellent link on Github for a Python app to read the data directly from you inverter. I downloaded the code onto my Raspberry PI, changed the config and it worked 1st time. This is also near-realtime and not 5 or 10 minutes late like on the Solarman website. Obviously the raspberry need to be connected to the same WiFi and subnet too. The Python app also provide much more data than the Solarman website.
