I just noticed this thread as well, the early models of the Ring door bell required a larger transformer if you wanted to activate the local chime at the same time as the networked chime, a 30VA. Skybell may be the same. The newer versions do not require a larger transformer as they are battery powered and the existing transformer just keeps them charged.
