// File: PS_MKR_THERM.cpp
// Authors: Dan G Ogorchock
//
// Summary: PS_MKR_THERM is a class which implements the SmartThings "Temperature Measurement"
// device capability.
// It inherits from the st::PollingSensor class. This class implements support for
// Arduino MKR THERM Thermocouple Shield.
//
// Create an instance of this class in your sketch's global variable section
// For Example: st::PS_MKR_THERM sensor1(F("temperature1"), 120, 3);
//
// st::PS_TemperatureHumidity() constructor requires the following arguments
// - String &name - REQUIRED - the name of the object - must match the Groovy ST_Anything DeviceType
// - 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
//
// This class supports receiving configuration data from the SmartThings cloud via the ST App. A user preference
// can be configured in your phone's ST App, and then the "Configure" tile will send the data for all sensors to
// the ST Shield. For PollingSensors, this data is handled in the beSMart() function.
//
// TODO: Determine a method to persist the ST Cloud's Polling Interval data
//
// Change History:
//
// Date Who What
// ---- --- ----
// 2019-06-23 Dan Ogorchock Original Creation
// 2019-06-24 Dan Ogorchock Improved false reading handling
