'Grid Down' alert on app?

'Grid Down' alert on app?

I have a grid-tied system with Powerwall 2 and photovoltaics. Recently I experienced an extended power outage, but by the time I became aware that PW was powering my home the battery was depleted to about 13%, not enough to get me through the night. I had continued to go about my regular chores, running lights, clothes dryer, microwave oven, and many other energy intensive activities which I would not do if I was aware of the grid outage. This may have been addressed already in this forum, but I was unable to find information here or in My Tesla. I made a suggestion to Tesla but haven't heard back. I live in a rural area and power outages are a common thing during winter, and a simple alert would help me to shut down unnecessary home circuits to prolong battery life. BTW the solar panels do a nice job of recharging the Powerwall 2 during summer, but not so much during winter. If anyone has information on this please share. Thanks, Paul

Yes, in winter it would produce less energy during a day. Days are shorter and the sun is lower over the horizon. Also powerwall2 placed outdoor, the low temperatures slow the charging process slower as well.

There is no "grid down alert" as such but the App does indicate the grid is down with a circled red "X" on the grid icon. Using some manual/scripted programming it would not be difficult to roll your own monitoring using some of the accessible URI's of the Energy Gateway.

I agree Harry, does site.instant_average_voltage drop when the grid is down? I can't check without throwing the main breaker here. To do so would ensure I have hell to pay from her who must be obeyed.

Thanks harrye
The circled X on the grid icon in my app is how I realized that the grid was down, but normally I don't check the app very often. I checked it only after 18 hours, when a neighbor called and said, "hey, I saw your lights on last night. Do you have power?"
PW 2 is so efficient that it switches over seamlessly...guess their product is too good.

I live in a rural area with flaky power supply as well. An alert via a popup or some other obvious means would be very helpful when the grid goes out. I'm not tech savvy enough to create my own script so I would very much appreciate this facility in a future upgrade of the app.

@steve I am in the same boat. Until then I guess I'll rely on my neighbors to knock on my door and tell me .
