I hear two low beeps when I plug in my device. My devices are configured but they are not uploading data.

If you run into this issue, it may be because your device has low battery.

After receiving your device and plugging it in, you may notice that your device makes two lower pitched beeps. These two low beeps indicate low battery. Once your device charges above a certain threshold, it should come out of deep sleep mode and begin uploading data. 
We recommend that you charge your device for at least 24 hours when you receive them. 
Once configured, you can view the battery percentage of your device on your Clarity Dashboard.  For more information on troubleshooting your device, go to Understanding the Device Status page
