Terminology
The words this documentation uses for the parts of Cloud, and what each one means.
Cloud - the product itself: remote monitoring, management and control for compatible devices, reachable from a browser.
Site - a collection of devices, usually grouped by project. Who can reach them, what they do, and when, is all configured at site level. See Sites.
Device - anything that can connect to a site: controllers, plus network nodes and gateways, and managed switches. (Where the portal has a published supported devices list: See Supported devices.)
Controller - a device that runs a project file. "Device" covers the wider set above; "controller" is used specifically where a controller, rather than any device, is meant. (Where the portal has a published supported devices list: The controller families this portal manages are named in the device list.)
For portal owners:
Portal - an account that manages several sites from one place, typically for an integrator or a multi-site customer. See About Portals.
For readers with multi-site access:
Multi-sites - a portal feature that groups several sites so they can be managed both individually and as a collective. See Multi-sites.
Task - a collection of actions that can run across several devices in a site. See Tasks.
Action - a single command a task performs on a device, such as firing a trigger or starting a timeline. See Task actions.
Task scheduler - a task set to run automatically, on a recurring or one-off basis. See Scheduling.
Site plan - the paid subscription that keeps a site in Active mode. See Vouchers.
Control Panel - a simplified interface built for the people who use a system day to day, without exposing the rest of Cloud. See Control Panel.
