It would seem logical to name them for where they are and what they do. “Bathroom motion sensor”, “Bedroom lamp”, etc. However, I’ve found that, if it can move, it ends up moving sooner or later. My “bathroom” motion sensor is now in the upstairs family room, for example.
i use a code like “nbrnw1” for like outlets and “nbrnw1&2” if its a dual outlet plug. Its a room code “nbr” and where/what device is, in this case “nelw” means "north wall. So “nbrnw1” is an outlet on the north wall of the north bedroom. “Ksw1” would be an outlet on the south wall of the kitchen.
