Hello,
It was set up with wifi, but its right next door to the router, and I fitted a direct ethernet cable between it, as the solar edge info is unclear whether it will transmit the data via the wifi connection - but either way the IP does change occasionally.
The installer didn’t have a clue really (and didn’t seem to understand what/why I wanted stuff changing, and just gave me his phone with the SetApp app on and told me to change what I wanted!
I’ll keep fiddling and see what happens…
