If you mean indigo, should work with any certified Z wave plug. For example, TKBhome makes a French style plug, model TZ68F.
You could also use Teldus : TZWP-101
Popp 123634 68E
Or NodOn ASP-3-1-00
One of the advantages of Z wave is that the certified plug should work with any certified Z wave controller.
If I am remembering correctly Aeon Labs and Fibaro also have French style plugs, but I don’t know the model numbers for those.
So you should be able to use these devices with indigo, vera, or the UK smartthings hub.
Indigo runs locally.
Vera has to be set up with Internet, but once the account is set up, the hub itself will run locally.
Smartthings is a cloud-based system.
But you can choose the plugs independently and as long as they are certified for Z wave they should be able to work with any of these controllers.
