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.

Considering the fact that just like Apple Home, HA dashboards strip the first part of the display name if it’s identical to the area name, I use the „area device“ convention. So „Bathroom Leak Moisture“ is displayed as „Leak Moisture“ under the area „Bathroom“.
Furthermore HA allows to recreate entity Ids after renaming a device resulting in: „binary_sensor.bathroom_leak_moisture“.
So if I move my sensor to another location, I simply rename it to „Attic Leak „.
