Advice requested on best hardware for motion lights

[ashen zodiac]

I have a set of fluorescent lights in my basement ran by a Single switch which is wired in without neutral. My dream is to install a smart switch as well as a motion sensor that interacts over zwave, that would activate these lights when motion is detected. Diving in I have found Lutron Caseta might be the Smart Switch I choose, As it does not require neutral, however I am confused on if I will need the Lutron Hub to interface with Home assistant.

The second part of this would be the motion sensor, I have very little knowledge When it comes to this technology so as part of my research. I am reaching out to the community.

How would go about Solving this problem?

is the switch just a loop up to the light fitting?
meaning the fitting has a switched live/ perm live/ neutral.
if so you can put a normal smart relay behind the light instead of behind the switch.

as for motion sensor. something esphome based with mmwave would be my suggestion

Yes, To the best of my knowledge, it is just a loop As the switch only controls the lights . I haven't even started to look at smart relays ,

On a wiring diagram, you would put it on the switch loop?

depends on the relay but basically yes

you could put something like a shelly behind the light

then for a mmwave sensor something like this or this would work

set the shelly to use the switch changing position as a toggle annd then you can keep the switch which will trigger the relay even if the sensor or ha is down
