http://www.smarthomeusa.com/ShopByManufacturer/Kelvin/Item/756990/Kelvin is a voice-interactive, fully programmable thermostat. It can be operated by pushing its buttons, all of which talk, or by simply talking to the thermostat, which responds to voice commands once it has been programmed. Kelvin can be programmed to lower the temperature daily at specific times of day, such as evening, and to raise the temperature the following morning. It can also be programmed for weekends or vacations, when the residence is unoccupied, and to then adjust automatically for periods when the house is occupied again.
