There have been a lot of threads complaining about issues with SmartThings lately.
I too am not a completely satisfied user.
I struggle with the long-term viability of the SmartThings model. I keep hearing people talk about how other solutions cost more, or require monthly fees, and everyone talks about how SmartThings is better in that regard. But, think about this.
You spend $99 on a hub. Since that hub will work with generic Zigbee and Z-Wave devices, in theory, that is all you have to give SmartThings, and in return, they promise to give you a cloud-based Home Automation solution forever.
So, hypothetically speaking, if SmartThings makes $10 profit on every hub (not very likely.) and they have 5 employees making $100,000 per year, they have to sell 50,000 hubs every year just to pay salaries. But, in order to support those 50,000 hubs, plus all of the hubs they’ve sold prior to that, they need to have infrastructure to handle the cloud-based home automation requirements.
The Google Play store says the ST app has been downloaded 10,000 - 50,000 times. If you figure iOS downloads are comparable to that, and every download is a hub (which would assume only one user per hub, which is not realistic), that means ST has sold at most 100,000 hubs.
Sure, they sell other things, like starter kits and sensors and thing shields (when they are in stock) but my assumptions are very conservative, and I struggle to see how this model is sustainable.
I’m using Home Automation as a hobby. I have been very careful to implement things in a way that if the hub goes away, all of my things still work the old-fashioned way. If you are looking for a perfect, 100% reliable, hosted solution that works forever for $100, you are kind of not being very realistic.
