Data gathered from the Sensedge can be stored both locally and in the cloud to make sure you don't lose a data point.
When Your device is connected to the Internet, all readings are automatically transmitted and stored in the cloud.
The Sensedge is also designed with a data buffer to ensure continuous data collection, with and without Internet connectivity. Its 8GB of built-in memory storage can collect more than 50 million data points, which is over 100 years of minute-by-minute readings. Should the device disconnect from the Internet, all readings are stored in the data buffer, and automatically uploaded to the cloud once Internet connectivity is restored.
