A monitoring device generates an availability index associated with the user for use by a client device associated with a remote user. The availability index is indicative of a probability of a successful connection between the remote user and the user. The availability index is based on user data associated with the user that is received from one or more sensing devices. The user data can be weighted such that user data that provides for a more accurate availability index is weight more than other user data. In this way, user data can be utilized to generate an availability index for a user that can be used by a remote user to predict a successful connection. The remote user can conserve resources as the availability index provides an accurate and reliable indicator as to the successful connection with the user.
