Like the title says, I have a 20yr old manufactured home with nothing but single pole speed boxes everywhere. All the wiring is 12-2 Romex (black/white/ground). So no neutral wire. Is there a Treatlife workaround or alternative I should be looking at?

I know there’s GE Cync and Lutron Caseta. Caseta might be a little too pricey for me. But I only have first hand experience with Treatlife, so not sure.
