two weeks ago I activated the photovoltaic system with accumulated powerwall2 cumulus, all worked regularly for a week, about 4 days ago the green LED on the powerwall start flashing and I will not be able to connect anymore the app to the device to get the system state.
Taking a look to the owner manual it seems to be a problem between gateway and powerwall communication, but I cannot find any documentation on how to access the gateway to verify the settings.
I thought there might be a network problem, there is an ethernet port on the gateway, can I use it to check the settings? Is there an IP and password to use? Is there a gateway technical manual?
