Well the advantage would mainly be you would be able to use other types in your IOS Home application like fans, garage door openers … (there is a fairly long list apple already supports) and as a result ask siri to “turn the fan on” or “open the garage”.
Good news is I managed to make it work, so for those interested have a look at this post
