As far as I understand it, one time involved a firmware update that had to be forced from the house (and that they didn’t feel comfortable walking me through) and the second time involved replacing the switch that detects loss of power from the utility and automatically switches the house to the batteries. They did work both inside and outside near the meter for that one.

Gotcha ya that switch is called the gateway or more like the brain really and NOT cheap!. It has a cellular connection as well as wifi and ethernet. As it's leased some options are N/A but you can log into it pretty easy just type it's ip and enter your tesla password and you can see real time usage and as it stays on the LAN you can still use it that way if your internet is out unlike the app.
