The Device Settings page is used to add, configure, and organize Devices and Display Groups assigned to your user account. This is also where sharing of Display Groups between user accounts can be configured.
A Device is a physical or virtual device containing one or more sources of data (i.e. sensors). Devices can be physical devices installed in a building or virtual devices, such as Green Button data, provided by your utility. Please see Appendix B for a list of supported devices.
A Display Group is a grouping of Device data sources (sensors) for display. Display Groups provide flexibility when presenting data collected from various sensors. They allow sensors (of the same type) from multiple Devices to be separated or combined for presentation in the MyEyedro Plugins.
Simply put, Devices are used to collect data and Display Groups are used to display the collected data.
