As you know, I am working for a smartHome solution in the corporation, which bases on SmartThings(ST) strategy. But as following, I am not feeling optimistic about this IoT solution. OK, I will tell you some reasons.
1) ST uses a hub to interactive with connected devices, which supports ZigBee ,ZWave and LAN protocols. Although I agree ZigBee/ZWave also good protocols for communication, especially interoperability, maybe better than WiFi and BLE. But in the hub, it manipulates ZigBee stack through Ember stack other than TI Zstack, which I think is also popular in the market. From the ZigBee Alliance proposal, there is still some barrier for interoperability between these two ZigBee stacks, not to mention devices using a 3rd party implementation for ZigBee.
2) Considering localization for China, it‘s difficult to utilize ZigBee devices as the export forbidden from USA government. Amazing reason!
3) Currently, for each type devices, you should prepare a specific Device Things Handler app to deploy into the ST cloud, which will frustrate the manufactures or device maker. Especially to the StartUps, it‘s a high level boundary for them to develop the app using groovy. Also, in the controller side, too many integrated app panels will lower customers‘ stickability
4) Almost all jobs are deployed in the ST cloud, data aggregation, analytics and action control message etc. This leads a low efficiency and high latency. In my opinion, fog computing(proposed by Cisco) maybe a good alternative to the concentrated Cloud architecture. The hub can be developed to more smart as a fog edge node, taking more workload.
5) Insufficient security strategy. There is OAuth for hub and cloud, but hub and devices, especially the 3rd devices, no enough authentication and encryption, just TLS in network layer. We should take more attention to this potential risk.
OK, apologize to my complaint, a startup solution will not satisfy our guys, but it will evolve and improve. Look forward more satisfied solution in a foreseeable future
