Another way besides the webconnect module is SBFspot, it connects to the inverter via Bluetooth and can send it to Home Assistant via MQTT.
You may have to open up that bottom panel to check which communication module you have installed (if you have one). That would determine the options to connect. For units that only have RS485 module, you can use Yasdi2MQTT to connect to the RS485 bus, and send the data to HA.
