I am trying to see if this is possible.
Currently I have Alexa with 1 US Smartthings hub, using zigbee and US frequency z-wave devices.
However since I am in Hong Kong with 240V I need to get some devices that is compatible with the voltage from the UK . Clearly they operate on a different frequency.
Would a 2 hub setup work?
Would I be able to control the US and European frequency z-wave devices via the same samsung smartthings app and have the same control via voice?
