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 give everything fun and whimsical names so when I have to actually fix something, it takes longer than necessary. 😃
I gave up pretty quickly on trying to name things. Early on I was having a lot of issues with zigbee, and I frequently had to reconnect things, and renaming them into my scheme got to be another step I just didn’t want to bother with. It felt like a waste of time.
A better use of time was fixing the zigbee issues (wifi interference - fixed that, and now the network is solid). But now I don’t really ever need to worry about the device names, so, eh.
