I have no idea about code where you live and I hate motion sensor lights in homes if you go all LED lighting there is no need to save energy with motion sensor lighting .

Most motion sensors are in the switch.

motion sensing for things like bathroom fans are great to run for 10 minutes after, etc. I am going to use some in bathrooms that don't get extended use and can be over-ridden.

I do, though, think the code still requires some switch...

If you have no knowlege as to the answer to a question…dont answer it? IMO im surprised you dont know the answer.

If you are in Canada, YMMV. Also California has Title 24. But for NEC Article 210 all habitable rooms require a switch for the lighting. In rooms other than kitchen and bath you may provide a switched receptacle for a plug-in fixture. You may install a sensor switch in place of a manual toggle. Verify the type, occupancy vs motion, and whether you can override the feature.

All code questions should be asked of the local code official.

I have no idea about codes, but I LOVE the motion-sensored light in my walk-in pantry and laundry. If I'm carrying a load of groceries or a basket of laundry, I don't have to walk into a dark room.

I think I'd like this less in a bathroom. I keep a nightlight on in a bathroom, and sometimes I go in at night and don't want the lights to come on. The lights seem "more jarring" in the middle of the night. Depending on the sensitivity of the light, it might come on as you walk down the hall past a half-bath; I would not like that.

I have to wonder if there's good way to adjust he setting based on time of day, etc.

I know my home automation system will gently bring up the brightness, so it would feel like they could turn on a bathroom light at 20% from 11PM to 6AM or something and you could override with the keypad

Nothing about this concept appeals to me.
