What's your use case? I haven't found anything that directly replicates all the features of the SmartThings Multi. Specifically, vibration seems to be pretty hard to find.

Aeotec makes a 6-in-1 that does motion, humidity, temp, light, UV and vibration, for a price to match.

I'd hit up eBay if you really want those exact features, since there's no telling when Aeotech will actually roll out their products, and I wouldn't be surprised to pay a premium for the privilege.
