Wyze’s authorized resellers only sell to the US. Non-US Amazon storefronts are not authorized resellers. (Even in the US, third-party Amazon sellers aren’t authorized) Wyze doesn’t have any control over this, unfortunately. It’s easy to import products over the internet, so it’s impossible to stop people from doing it. But it’s not part of their business plan at this point, and they don’t offer international support.
Wyze isn’t a home security system.
