I too have major issues with the NEO gateway. With my original system it was always dropping the connection, or connecting to my neighbors gateway. Tesla was no help and I was working almost every day trying everything to re-establish the connection to no avail. When I added additional solar and 2 Powerwalls to my system a year and a half ago, my problems went away for over a year. I thought (and was told by my install tech) that I no longer needed the NEO since everything went thru my new Tesla inverter. Then in January of this year, I started getting emails and texts out of the blue that my system had lost communication - although the app was accurately reporting my data for both systems via the tesla inverter. I called Tesla to ask why I was getting the message and they said I should still be using my NEO box in addition to Tesla Inverter. Been struggling ever since to get it to work. It did work for a few days (according to app) but no blue light on my inverter, then started receiving inconsistent and spiky data like noted above and now just a flat line. I think I need to just give up since my data appears good via the Tesla inverter and that data matches SCE. My only concern would be missing out on any firmware updates and/or backroom performance monitoring.
