|
|
// Summary: st::PollingSensor is a generic class which inherits from st::Sensor. This is the
|
|
// parent class for the st::PS_Illuminace, st::PS_Water, and PS_TemperatureHumidity classes.
|
|
//
|
|
// In general, this file should not need to be modified.
|
|
//
|
|
// st::PollingSensor() constructor requires the following arguments
|
|
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType tile name
|
|
// - long interval - REQUIRED - the polling interval in seconds
|
|
// - long offset - REQUIRED - the polling interval offset in seconds - used to prevent all polling sensors from executing at the same time
|
|
