1. A method of managing a site in a mobile environment, comprising:

  • detecting an availability of at least one network device at a site wherein the at least one network device has an operating condition;

    detecting a first boundary of the site having a first boundary distance;

    detecting a second boundary of the site having a second boundary distance that is different than the first boundary distance;

    detecting a plurality of zones including an on-site zone including an area within the first boundary, a first zone including an area beyond the first boundary and within the second boundary, and a second zone including an area beyond the second boundary;

    detecting a distance of a mobile device relative to the site;

    initiating a change to a temperature set-point of a thermostat at the site in response to detecting a change in the distance of the mobile device relative to the on-site zone and the first zone and the second zone;

    initiating an on-site temperature set-point corresponding to the on-site zone;

    altering the on-site temperature set-point to a first zone temperature set-point corresponding to the first zone that is different from the on-site temperature set-point; and

    altering the on-site temperature set-point to a second zone temperature set-point corresponding to the second zone that is different from the on-site temperature set-point and the first zone temperature set-point.
