Looking for Smart Lighting Architectural Options

@Acevis - Thank you for your time and ideas. Its really appreciated.

Hue’s are outside my budget but the osrams are plausible. It would seem based on your suggestions I’m in the same boat as R2D2 on this thread The cheapest GU10 ZigBee Light-Link bulbs around !?!

Eight lights @ €30 = €240, Osram Hub (if I want to upgrade firmware) €60. I like the idea though of the light switches I must admit. I know I saw an example of a wall switch in some thread and people were creating 3D surrounds over existing light switches. I can not find the thread nor quick searching showed up something I could relate too, but is the basic premise that the switch is battery operated and is connected with the bulbs for on/off functionality. If this is the case is everything still possible to connect to the ST App for control?

Alternatively

or

and I need two because I’ve 4 wires (which I’m assuming controls 2 lights each)

Were I to go with the Relay switches, can a Zwave light switch also be used???
Also does anyone know if you can have two ZWave light switches running the lights. ie there are two doors to the living room, one light switch at each door?
