Something that was pointed out to me (embarrassingly) is that this method is not secure. Sending unencrypted information to the Hue bridge, which includes the auth, would allow an attacker to send their own API calls to the bridge. One of the API calls could have a security hole that could be used by an attacker / curious person.
