American hub but 220v aussie

Hi mate - I’ve only just gotten to the point where these will be installed on Wednesday. Looking into what you mean, it doesn’t sound cool. I need to know the status of both switches. in searching, I’ve found this apparent solution: Monoprice Dual Relay On/Off Device type 11990

Now I’ve just got to work out how to add the devices as this ‘type’, which I’m sure I’ll find around here some place.

Any thoughts on this approach jjhamb?
