The device has a local LCD display which either shows the temperature or the humidity. 4 buttons allow switching between minimum, maximum or actual values, humidity versus temperature and Fahrenheit versus Celsius The device can report its values via Z-Wave and allows to set trigger level for direct control of other Z-Wave device when the measured value hits the trigger point. This makes the ST814 a very powerful and flexible tool to measure environmental values and control device within a Z-Wave network.
