Heyho,
I am looking for smart devices - currently interior blinds and lights that support Zigbee - and thought why not take a look at the European market.
As far as I can tell most products come from china, but maybe someone here knows more than me :)
EDIT: So sadly it looks like there is no real european smart home stuff out there.
Codeatelier (German) and their homee cubes can be great and I have been using that system for years now. They do not sell components - only the smart home hub and cubes for different wireless protocols.
