The satellites just relay signals from a customer ground station to a Starlink-owned ground station. That ground station has a wired Internet connection. So coverage at your house is dependent on you and a Starlink ground station being in the ground track of some Starlink satellites. Because of their low altitude it's entirely possible for your house being in the ground track of satellites but the nearest Starlink ground station being outside. At some point in the future Starlink satellites will have laser communications between each other. Then only one in that group needs to be able to see a Starlink ground station and the others can route customer signals to it.
