Spyder Robotics Herpstat. No thermometer, won't text you unless they made a new model that can do that. But they do have an alarm when the threshold for highest and lowest temp is passed. Then it shuts off (Supposedly). The alarm do work for sure, not super loud but keeps beeping until you either stop the alarm; temp goes back to normal; or I think in about 30 min, it will shut off the heat on its own.
