Yep, but it also has it’s own z-wave built-in. An RTS signal alone would need to be converted to z-wave with the ZRTS-II device (or the TaHoMa hub) in order to work with SmartThings. I’m unclear if the CLEVER would integrate with ST via it’s z-wave antennae, or via ZRTS-II since I’ll have that technology handling other windows in the house. Also unclear if it’s via Custom Device Handler, or native integration. (Using custom/community developed stuff scares me at this point because we know that Groovy is out-the-door very soon).
