IMHO and my own personal preference, I refer you to my post on naming wish list items:
With respect to the guidance provided in the Renaming Devices blog post, using their fridge example, I would name them Fridge Kitchen and Fridge Garage as opposed to Kitchen Fridge and Garage Fridge. The reason for that, as detailed in my previous post, is that I find it more useful/informative to see all my Fridges sorted next to each other in the Sense app. If you were more interested in understanding all the items in a given space, then you could name them the other way around. Alternatively, if there were another characteristic that was most important to you and common across several devices, that attribute could take the lead position in your name. (This is essentially the default provide by Sense’s initial categorization, e.g., Motor 1, Heat 3, etc.)
Think of naming as your first pass sort for grouping devices. You can always pull the data and post process to group in any way you find useful, but without going that far, your name provides that capability.
