This app provides a convenient way to access eGauge devices (meters) from your phone or tablet. It will automatically select the best connection to the device, whether that is the local network (LAN), the cloud, or Bluetooth (for devices equipped with an optional Bluetooth dongle). The app can be set up to automatically connect to your device on startup. It can also provide access to multiple devices that are managed as lists of favorite and recently accessed devices. The app will periodically check favorite devices for pending alerts and report them. We recommend upgrading devices to firmware v4.1 or newer when using this app. Use Settings > Tools > Firmware upgrade on the device to upgrade to the latest firmware version.
