It sounds like you may be trying to buy a US hub through a U.K. distributor.
The mass-market (as opposed to kick starter) UK version of the hub was released at the same time as the V2 US version was released. But the UK version was not called either V1 or V2: it was just called the UK version.
That version is widely available for about £99 at curry’s and from third-party sellers on Amazon.
The only ones I see marked “V2” are actually US versions of the hub.
The differences are not in the power supply, however. Rather, it’s in the Z wave frequency that is being used. Those frequencies are different for different regions, primarily because they can conflict with mobile phone frequencies which are different in different regions.
I know the frequency which is assigned to Israel is different than the one assigned to either the UK or US. In some countries it is illegal to operate devices on the other region’s frequencies: I don’t know if that is true in Israel or not.
You cannot change the frequency of a hub after it is manufactured, mostly because of this legality issue.
And any devices you use must match the frequency of the hub exactly.
So you do need to decide which Z wave frequency you want your hub to have. It would make sense if you chose the UK/Europe frequency because then all of the end devices would be using the right voltage. Again, though, I just don’t know if that zwave frequency is legal to operate in Israel.
But if you do want a UK hub, you don’t need to be looking for a “V2” UK hub-- they haven’t made one of those yet. Just the original mass-market UK hub.
