If SmartThings could be compared to Android, Wink was the Apple equivalent. While SmartThings is "open source" for community development, for the most part Wink was a closed ecosystem of devices. They only supported devices if the companies paid Wink. Their software was well polished, though it still had a bunch of bugs. And their automation was pretty basic compared to what you can do with SmartThings. Wink is what got me into smart home tech - back in the early days they had a ton of cool hardware that they supported and it seemed like they were always coming out with new stuff, but then Quirky (who owned Wink) sold them off, then they got sold off again, etc. Frankly, the writing has on the wall for a LONG, LONG time. I think the first real sign was when Wink accidentally bricked all their hubs when they forgot to renew their SSL certificate. They were able to come up with a work-around to get your hubs back online but if you weren't techy enough to change your DNS servers your only option was to ship your hub to them for them to fix and they'd ship it back. I twas quite the disaster. I feel like they never really recovered from that.
