Looking for devices support 220V and do not need neutral wire

[JDRoberts]

First things first:

The SmartThings hub is currently made only for the U.S. Zwave frequency. That may change for version 2, we don’t know.

But different countries use different z wave frequencies, so the first thing you need to figure out is what z wave frequency is legal in your country.

After that you can look at the voltage requirements.

FAQ: SmartThings international function

Hello all. I am fairly new to the HA field, and I have been extensively researching and settled upon smartthings as my number 1 choice for a smart hub. However, I live in the Caribbean and I am just curious about one thing in particular. I realise thst there are US, UK and other z-wave frequencies etc. so my question is : if I buy a US version of the smarthub and all US accessories (sensors etc), will it work even though I am outside of the US? I know that buying UK “Things” won’t work with a US hub, so I’m just curious. Do I need to be literally in the US or can I just buy all US components and expect the system to function as advertised. EDIT : Also where I am from, we have the same specs as the US (110-120 v 50-60 hz).
