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.
Yeah, if they’re moved I’ll likely want them to perform different automations and such, so I just completely delete tte device and re-set it up.
