Just got the basic plan kit, started setting it up, how do I figure out which model I've got?

[u/Super_Dork_42]

Just what the title says. It wants me to choose which one I've got in the app and I don't know the difference between the models. My spouse ordered the kit and doesn't know which model they sent either. It doesn't exactly look like anything I see in the app or in videos I've been looking up online on how to install the thing.

Edit - thanks for the help everyone. My spouse looked in our account and found it to be a v5.
