Will Z-wave device manufactured in US work in INDIA? (if we use ST manufactured in US)

The above works very very well with sonoff. and they as such do not have any product directly comparable with inovelli. The looks of it suggests it wont fit into the wiring closets. Neither is sonoff. It wont go in indian wiring closets at all. Either I will have then in a individual live wires or on a separate box which will go into TV cabinet.
Another one which goes into the wiring closet but works somewhat ok is aeotec smart relays.

Thanks
