In the previous exercises, we have created a system, data collections, services, libraries, triggers, and timers. Essentially, we have a very basic but functioning system. Users granted access to our system, however, do not have any visibility into our system or the data being sent to our system from devices.In this exercise, we’ll create a portal and grant access to the portal to users of our system. We’ll also add widgets to the portal that will provide users visibility into our system.
