Is it possible to get switches, readings, other from two raspberry pi’s on one dashboard rather than separate devices?
Of course, you can get as many as you want widgets from a lot of different devices. You just have to make a project and then drag and drop the device. After that you will be able to choose what (if not all) widget from particular device you want to add
If you have some problems, I can make you screeshots, but it is very easy and intuitive.
