Using humidity, temperature, light and movement sensors this new IntelliSwitch allows full manual or fully automated operation of the lights, fan and towel rail in your bathroom. It has a battery backup in case of power outages and it all fits within a standard light switch plate. A big step forward in bathroom automation.
