@curatedjenny Depends on the case for me; I wouldn't mind it being there if it was someone else's setup (maybe it couldn't be hidden for practical reasons!), but if I were the one designing the setup, I would be inclined to try and keep it out of sight if I can.
@joepie91 I get you. I'm in agreement with you, I think. On a practical level you sometimes have to see the device (if it has a display: this might mean it's meant to be manually read by a human rather than sending data to the cloud), but often that's not the case.
@curatedjenny (Notable context: I do not work in this specialization at all, so I don't know what is and isn't possible, and this is just a general tendency to make things look aesthetically nice)
