The Zooz won’t work for Europe : wrong zwave frequency. 
I keep hearing rumors that Zooz intends to eventually come out with some European models, but nothing has been officially announced yet.
With Zwave, the frequency of the end device has to exactly match the frequency of the hub or they can’t talk to each other.
As far as hue, For the sensor you have to connect it to a smartthings hub, not a hue bridge. That used to require a cloud connection, but now, with the new edge drivers, it will also run locally. 
Edge itself is still in beta so there might be some glitches, but there is a community created edge driver for the hue motion sensor if you want to try it.
