System Alerts and Notifications
You may receive push notifications and/or alerts in your Tesla app when your system experiences issues that may require basic troubleshooting, or when your Powerwall changes status such as Going Off-Grid or when Storm Watch activates. Your phone and Tesla energy products must be connected to the internet to receive push notifications and alerts.
Note: Internet connection may be unavailable during some grid outages, preventing delivery of Tesla app notifications.
