Need light switches that works with no neutral line

Hi,

I have a 4 way installation and a 3 way installation that doesn’t have neutral lines. Can someone recommend a light switch (primary and slave) that supports SmartThings and doesn’t require Neutral.

I use GE ZWave elsewhere in the house and work great but can’t use it where I don’t have neutral as they have to have them in order to work.

Lutron is not a solution since it appears not working with smart things.

Thanks,
IK
