Power Grid Monitor

About this app

Power Grid Monitor helps you detect power outages using an Android phone or tablet connected to the power source you want to monitor.

Turn an Android device into a Power Node: enable power monitoring, connect its charger, and the app detects power loss and restoration events.

Use two or more devices to build your monitoring setup. Leave one device connected as a dedicated Power Node, then install the app on your everyday phone or other devices and configure them to receive remote alert notifications. All devices registered with the same account can work together.

Key features

• Monitor charger power changes on an Android device.
• Detect power outages and power restoration events.
• Receive local audible alerts on the monitoring device.
• Receive remote push notifications on other registered devices.
• Configure each device to monitor power, receive remote alerts, or perform both roles.
• View your Power Nodes, their latest status, last contact, and recent activity using the same account.
• Acknowledge outage alerts and keep a history of power events.
• Pause monitoring during maintenance or planned power interruptions to avoid unwanted events.

Power Grid Monitor can work locally without an account for audible alerts. Remote alerts, Power Node synchronization, account history, and status updates require an internet connection and notification permission on receiving devices.

Reuse an old Android phone or tablet as a dedicated Power Node, and use your everyday phone to receive alerts and follow the status of your monitored locations.
