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.
Generally, and for a number of different reasons, it’s best to disassociate a device that is meant to be permanent and re-pair with HA. There’s a whole lot of automation in the background that goes into pairing a device, or setting up schedules, automations, scenes, scripts …etc. Deleting forces a find/clear on that entity, and re-pairing creates clean new entries.
Yeah, I was confused about some lamp always being on when I woke up, and realised I’d replaced it’s smart socket with one that had previously been used for a coffee machine. Deleting and repairing sounds like wisdom.
