Anyone aware of a means to upgrade the Tesla Gateway V1 cellular 3G modem?
Tesla installed Q.cell panels, SolarEdge invertors, Tesla Powerwalls, and Tesla Gateway (v1) at the end of May 2020.
AT&T announced the end-of-life of their 3G cellular support in July 2020 with an expected end date in February 2022.
Gateway had previously been connected via Ethernet over house electrical wiring and had the 3G cellular option as a backup.
Last night during a grid outage was the first time I had noticed that this function was gone and that it had some sort of effect on how I use, reach, and monitor the system.
The outage last night also impacted the Internet service provider beyond the house too.
Without the cellular connectivity even with having paired the phone to the Gateway/Powerwalls I was unable to do anything with the system.
The app while connected to the Internet via my phone was able to get the last known state of the system and continued to report that for about 15 minutes of the outage.
The app eventually reflected the outage with a message about not having current information.
We had power through the duration of the grid outage, but no way through the app to monitor remaining charge levels in the batteries.
I could of course, buy a cellular modem for the house or one that uses the Ethernet port of the gateway. But, that is less desirable to me than seeing if Tesla might have an upgrade program for the cellular model and continue to have them pay for the cellular connection fee with the carrier.
Edit: I could have web browsed to the gateway to see the status, but I would prefer to use the app only. As well as that requires being physically present by the gateway too.
