[Chris] sent in the Thermosmart. It is an Arduino controlled thermostat. It has a web interface which allows him to see the current temperature and make adjustments from remote locations. He can set heating or cooling to on, off, or auto and adjust the ranges as well. Weâ€™ve seen similar done with an Arduino before, even one with a nice LCD interface. This could possibly be useful for remote plant monitoring as well.
This is a nice hack for Earth Day.
