I’ve been eyeing up SmartThings for years, but with every CFL/LED-compatible light switch requiring a neutral wire, I’ve been holding off - I just don’t have the sort of cash it would take to have an electrician rewire my house. While waiting for the hub 2.0 to come out, I picked up a Wink hub - it’s cheap, the hub and compatible devices are available at Canadian Home Depot stores (as opposed to having to order most SmartThings devices online and pay for shipping and customs across the Canadian border). Now here’s the really curious thing - the conventional wisdom which I find everywhere in these forums (and everywhere else on the internet) is that any in-wall light switch that will work properly with CFL/LED bulbs requires a neutral wire. We all know the drill - low current draw, flickering, humming, etc. etc.
So here’s a mind-blower: Lutron’s Caseta Wireless devices, which will work with my Wink hub, state that
- They do NOT require a neutral wire
- The ARE compatible with LED/CFL bulbs
So how do they do it? Everything you read on this forum and elsewhere says it’s not possible. Is the conventional wisdom nonsense, or are Lutron using stolen alien technology or something? If they can do it, why can’t anyone else?
One day I really want to switch to SmartThings. More sensors and devices available, more power in automation (Wink is unfortunately pretty limited), and now with Hub 2.0, local processing. But no support for Caseta Wireless. Honestly it would be cheaper to keep my Wink hub just to control a bunch of Caseta Wireless switches, and integrate that with SmartThings via IFTTT or something, than to have an electrician re-wire my whole house to pull neutrals to all the switches. I’d rather have just the one hub, but if I have to have two, I can live with that. Are we likely to see some other switch manufacturer pull off whatever magic Lutron is pulling off to work with LED/CFL without the requirement of neutral wires?
