This situation comes up for people who are in South America and in parts of Asia. They use the US Z wave frequency but have 220 voltage.
I think most people end up going with the Aeon Labs in wall micro relays when they have this set up. They can handle the voltage and have the USC zwave frequency so they can talk to a US hub. They do require a neutral, but it doesn’t have to be at the switchbox – – it can be at the light fixture or elsewhere on the circuit.
