I know the WeMo devices can connect to the SmartThings hub…however…can the reverse happen?
Interested in connecting a Multi-Sensor to the WemoLink (main reason is I don’t want to spend another $100 on a hub for one sensor 
)
Not direct… but you could do something like… WemoMaker>IFTTT Maker>SmartThings
Or maybe get rid of the IFTTT and use wemo maker directly? Not familiar enough with either to know their capabilities.
