Through the use of a secondary phone or tablet, remote monitoring of your valuable is available through the Boveda app. The secondary device acts as a bridge to your sensor. Both phones must be running the latest version of the Boveda app. The secondary device must be left within range of the sensor with the app running. Sign into the same account on the primary phone you plan to take with you. Data will continue to sync with the bridge device and be downloaded to your primary device from the cloud.
