How do I unpair a device?

To remove a device from the system correctly, open the Settings / Information page for the device and tap the 'remove' button. Once you confirm that you want to remove the device it will be unpaired from the system. Alternatively, long-press the device's icon in the home screen, or tap the edit button, to show the delete buttons for each device. You can then remove a device without needing to open the settings page, which is useful for removing devices in the event that one has failed or can no longer be reached by the app.
