As a side note, do US z-wave or Zigbee devices work on a different frequency to the UK? Can I buy something from the U.S. and have it work here?

The short answer is no.

The long answer is in the international FAQ:

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).

The smartthings hub itself is sold in one of two Zwave frequencies. The UK one will work only with devices on the UK zwave frequency. The US one will work only with devices on the US Zwave frequency.

The zigbee sensors and other SmartThings-branded devices sold for the US hub use “boosted Zigbee” which is illegal in the UK. So again you need to get the UK version.
