We are moving into a new home next week and will be up-grading to the hopper system from the old 622. There are only two of us, so what we need is one hopper and two joeys. Am I right in believing that I can get a hopper for the living room, a Joey for the bedroom, and a wireless Joey that I can move back and forth between the garage and a second bedroom? If so, is moving the wireless Joey simply a matter of plug and play at both locations? This is in a 1900 sq. ft. One level home. Thanks.
