I've had a quick look online to help me, and I can see that my wifi name doesn't have a 5 after it and there is only one version in the wifi list.

It's annoying isn't it? I got two.. they work well, but lack of Ifttt support is a pain. I don't know why they came up with a whole new line of products (Tapo) when they have Kasa. I can only imagine...
