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.
Your only option are those higher-cost proprietary systems like Caseta, a wifi system like Treatlife uses requires a neutral.
Your other options is a control is at the fixture where a neutral is present rather than the switch and getting battery remotes, or running a neutral wire.
+1 use a zwave or zigbee relay in the fixture junction box where a neutral has to exist. Use the existing switch as the local control for that relay, and that should work. I use the same setup in a couple spots in my house where pulling a new run with a neutral would be a pain.
