There are 2 widgets for the dashboard that allow you to see multiple RWIS in a single place. Both can be added using the "add widget" in the bottom right corner of the dashboard screen on the Portal. Both can be resized or moved on your dashboard to your liking. The widgets are called :
RWIS Gallery
RWIS Feed
RWIS Gallery will be a window that will display the last photo taken from each RWIS all together, the name of which will be near the bottom left of the picture so you know which is which. If you only want to see one or more specific RWIS, there is a dropdown at the top of the widget which will allow you select which RWIS you want to be visible at the time.
RWIS feeds are a way to permanently group these together and display in a similar fashion to the gallery. You would go to the "Devices" menu in the blue lefthand ribbon, select "RWIS Feeds" and hit "add" in the top right corner. Give your feed a name and hit save. You can then click on that feed once created and add which RWIS you would like to be part of that particular feed for display on your dashboard. Multiple feeds can be created to switch quickly.
