No problem - enjoy! There are all sorts of cool automations you can do with pretty simple scripting - I found loads of examples online (and ChatGPT was useful too ;-)).  Monitoring battery SOC, voltage levels, error codes, on-grid/off-grid status, etc. Sending out notifications to the Home Assistant app on your phone is built in as an action, which I found useful.

Post lost, but let's try again.
I've got the same setup, and very happy with the integration.  If you've got the Goodwe interface installed, can you see the integration? (Settings > Devices & Services).  You should see the Goodwe integration listed there.  If you click on that, it'll give you a list of all entities to use, and show you what value your inverter is currently outputting for each entity. This can help you figure out which entity matches up to with value.  But - high level:
1 & 2 - you can use sensor.on_grid_export_power for both of these - it'll be either positive or negative
3 - For solar production you can use senser.pv_power, or sensor.pv1_power & sensor.pv2_power if you have multiple strings
4 - All my battery stats are available via the goodwe interface, but that might dependent on the battery type and BMS (I've got pylontech). Try sensor.battery_state_of_charge and sensor.battery_power, etc.
As for cards - just a few simple gauges and graphs go a long way! Lots you can do around monitoring and notifications too.
 

 

 

Excellent - thanks very much! I'll take a read through that, but you've been a great help.
