An electrical device for providing a visual alert to one of a neighbor and a home sitter that the temperature of the home has dropped below a predetermined temperature when a homeowner is absent. The device comprises a plug in unit for plugging into a standard three prong wall circuit. The plug in unit is designed to control three separate circuits. A solid state thermostat is disposed within the plug in unit, such thermostat having a preset temperature for activation. A switch is electrically connected to such thermostat for triggering a first circuit of such three separate circuits to turn off and for activating a second circuit and a third circuit of such three separate circuits when the temperature drops below the preset temperature. A lighted means is connected to the switch and the plug in unit for providing a visual alert when one of the temperature drops below the preset temperature or in an event of a power failure.
