Abstract: A secure wireless thermostat and system comprising the thermostat are described and taught. The temperature control unit replaces the traditional thermostat by attaching to the wall and using the existing wiring from the traditional thermostat. This temperature control unit has no display or programming buttons, rather a user interacts with the temperature control unit via electronic devices such as smart phones, laptop computers, and desktop computers. The settings of the system can be modified by the user from these access ports. If the user opts to interact with the system via a third party IP server, a local DHCP web server can be employed to store data safely and securely.
