As a resident of Germany and being a backer from the very beginning, here are my thoughts on migrating to the new SmartThings hub v2 and the Z-wave problem involved.
Please have a look at my (future) setup and tell me what you think:
Currently approx. 30 devices:
– Hub v1 (EU z-wave)
– SmartThings water sensors (EU Z-wave)
– SmartThings open/close sensors (ZigBee)
– SmartThings presence sensors (ZigBee)
– Phillips hue (230V, ZigBee)
– Belkin WeMo switches (230V, WiFi)
[– PlantLink (WiFi?)]
If my understanding is correct, the only future problem with the hub v2 here in Europe would be the US z-wave frequency.
Therefore, I would still use hub v1 for the communication with my EU Z-wave devices and use hub v2 to connect the future US Z-wave devices, e.g. First Alert Smoke & Carbon monoxide detectors. However, that would mean setting up two separate SmartThings environments.
On the other hand, if hub v1 would serve as a range extender for hub v2, I would only need to set up one SmartThings network. Here it would be important to know how the two hubs would communicate with each other (no Z-wave involved).
It seems to me that with this setup it would be possible to use both the US Z-wave and the EU Z-wave frequency in one single SmartThings network. If my assumption is correct that would solve the connectivity problem for all international backers (hub v1 with different Z-wave frequencies) who could otherwise not migrate any of their Z-wave devices to the new hub v2 network.
Please tell me if you agree to my thoughts or if there is an incorrect assumption.
