A number referring to the value of a point on an EventSensor. If the point class is temperature, then this object is the temperature in its configured scale (default is Fahrenheit). If the point class is contact closure or relay, then this object is either 0 (open) or 1 (closed). If the point class is humidity, then this object is the percent relative humidity. If the point class is analog input, then this object is the signed input value in tenths of the configured units. For any point class except relay, this object is read-only. For relays, setting this object to 1 closes the relay, while setting it to 0 opens it. Setting it to any value greater than 1 closes the relay for that many seconds (up to 3600), after which time it opens the relay. This works regardless of the control mode of the relay.
