That’s the Mimolite. It’s on the official “works with SmartThings” list. It’s a popular device in the community, but it’s limited to one input and one output. The Mimo from the same company allows for four. I definitely wouldn’t buy it off of eBay, though – – most Z wave device manufacturers will not honor warranties for devices bought off of eBay and some of them are counterfeit or even the wrong one in the box. And even so, it’s probably more money than you do want to spend on this kind of project.
For home automation systems it’s generally better to buy from reputable dealers who will take defective devices back. (It happens.) Some of them will also offer a volume discount if you ask.
But again, for this particular project I think most people have gone in a somewhat different direction for the integration. If you check the projects list you’ll see quite a few different approaches.
