Using AUS Zwave devices with the US SmartThings?

[JDRoberts]

@MaxSmart

Is there a way to run Zwave sensors that are AU spec on a US SmartThtings system? I suspect there is an AU spec Zwave receiver/hub that could integrate with the US SmartThings to facilitate this?

No.

You answered your own question–they use different radio frequencies. There are no bridging devices for this purpose.

Nothing to do with SmartThings – The company that makes the Z wave chips has assigned different frequencies to different regions and expects them to be used in that fashion. The frequency is set at the time of manufacture and cannot be changed after.

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).

If you can get an Australian frequency Z wave controller that has a cloud service or an IFTTT channel you could communicate cloud to cloud. But that would introduce both complexity and lag.
