Tesla app update lets Powerwall owners keep an eye on their electricity - The Verge

One powerful app...

"The new app lets customers monitor all their Tesla products including the Model S and Model X vehicles, Powerwall, and solar panels. Real-time data on solar power generation, battery power flow, and household energy consumption are displayed. The app can also notify customers of a power grid outage and share info about current Powerwall status and that the battery has kicked in to keep the home powered up.

In the event of an anticipated power outage, either planned or because of possible bad weather, Powerwall owners can also adjust the amount of power stored by their home battery pack."
