 *  MiniSplit App
 *  Functions:
 *		Controls my dumb Fujitsu mini splits in conjunction with Broadlink IR blasters, and an HE Virtual Thermostat device
 *      Allows for using mini split Dry mode as part of cooling process, or stand alone.
 *
 *		I wrote this after attempting this with RM, it's just to slow and tedious for coding complex logic, IMHO.
 *		Also I could not get the HVAC manager app functional with my Fujitsu devices
 *
 *	Preinstallation Requirements
 *	1. Install IR Blasters, this app is designed to work with Broadlink devices using the now withdrawn Broadlink Mini Driver app at
 *		https://community.hubitat.com/t/withdrawn-native-broadlink-rm-rm-pro-rm-mini-sp-driver-rc-hvac-manager/31344
 *
 *  2. Create working IR code sets for cooling (multiple temperatures), heat (multiple temperatures) dry, off, and more as necessary
 *
 *  3. Must have a working Virtual Thermostat (or perhaps a real device).
 *		I use a Virtual Thermostat averaging temperatures from 3 devices using the HE Average Temperature app at
 *		https://github.com/hubitat/HubitatPublic/tree/master/example-apps
 *		Changed the app created child from a virtual temperature sensor device to a virtual thermostat.
 *
 *	4. A dashboard displaying the Virtual Thermostat device or some other method for control
 *
 *	How to store Mini Split IR codes for Fujitsu units. (Your remote key names and setup may vary)
 *	1. Set mini-split device power ON, pressing the remote's Stop/Start key. Mini-Split device powers on with last setting stored in the REMOTE device.
 *	2. Set device to exact temperature, mode, swing state, louver settings, and Fan (auto suggested) speed, and other settings wanted
 *  3. Press remote's Start/Stop key setting power to OFF.
 *  4. Set IR blaster into learning mode
 *  5. Aim remote at the blaster then press remote's Start/Stop key, setting power ON
 *			(the Off IR code is sent anytime power is On)
 *  6. Save and name the IR codes
 *		My IR code names and settings
 *		AC On2169 - Mode: Cool, Temperature 21C 69F, Fan: auto (swing, louvers and other settings: whatever you want)
 *		AC On2271 - Mode: Cool, Temperature 22C 71F, Fan: auto (swing, louvers and other settings: whatever you want)
 *		AC On2373 - Mode: Cool, Temperature 23C 73F, Fan: auto (swing, louvers and other settings: whatever you want)
 *		AC On2475 - Mode: Cool, Temperature 24C 75F, Fan: auto (swing, louvers and other settings: whatever you want)
 *		AC On2577 - Mode: Cool, Temperature 25C 77F, Fan: auto (swing, louvers and other settings: whatever you want) not currently used
 *      ACDry74Swing - Mode: Dry, Temperature: 74F 25C Swing: On (swing, louvers and other settings: whatever you want)
 *				Dry may or may not utilize temperature or fan speed setting depending upon the mini-split hardware,
 8				check the manufacturer's operating manual
 *      ACFanSwing - Mode: Fan, Temperature: n/a Swing: On (swing, louvers and other settings: whatever you want)
 *		AC Off - Mode: off
 *  7. Adjust IR code names in the code as necessary
 *
 *	Notes:
 *	Most Mini-splits use Celcious for native temperature settings. When using Fahrenheit, temperature is appoximate.
 *	Most Mini-splits have a built in non accessable thermostat.
 *  IR communication is one way, from remote or IR blaster to mini-split
 *  When an Ir code is store with a blank in it's name, the Broadlink app replaces the space with a _ character.
 *		However when specifying the name in the sendStoredCode command, the _ character cannot be specified.
 *		Probably best not to use embedded blanks with IR command names. I learned the hard way.

 *
 *  Jul 19, 2022	v0.1.6 Change cooling to use newly added non-swing codes
 *  Aug 20, 2021 v0.1.6 Add support for Dry codes with temperatures using mode Dry and Dry+ 
 *									added codes ACDry(72|76|78)Swing used along with existing ACDry74Swing
 *  Aug 09, 2021 v0.1.5 When cool: change to use colder settings making  fan run faster in auto mode and perhaps blow colder 
 *  Aug 09, 2021 v0.1.5 add support for dry+ mode same as cool but only uses dry. Must set cool temp prior to setting dry+ no temps are shown
 *  Jul 22, 2021 v0.1.4 delay on dashboard due to additional 2 second delay. Change order of IR command and dashboard display update
 *  Jul 20, 2021 v0.1.4 in qHandler routine double send command due to occasional missed IR Blaster command sends, or mini-split device failing to respond
 *  Oct 15, 2020 v0.1.3 Add flag that stops this app from processing HSM Away and Night Mode changes when using Thermostat Scheduler. 
 *  Oct 14, 2020 v0.1.2 When outside temperature below setting value, do not use now inefficient MiniSplits for heating divert to baseboards, except on emergency heat.
 *							Fix issue where heat and cool would not occur.
 *  Oct 13, 2020 v0.1.2 Setup for individually controlling each miniSplit. Add Label to define app name. 
 *  Aug 15, 2020 v0.1.1 Add optional command queueing to buffer and remove many unneeded commands that may conflict
 *							due to commands entered from dashboard such as temperature down or up tapping on icon
 *							This is in addition to the Temperature Handler delay
 *						add optional input setting for number of milliseconds to delay command runin from 0 to 2000 default 1000
 *							This slows things down a little but hopefully stops a deluge of commands and IR triggering
 *  Jul 19, 2020 v0.1.0 Add optional user coolplus dry and fan offsets overriding hysterisis
 *						Display MyCool set points or Dry and Fan
 *  Jul 14, 2020 v0.0.9T Occasional error on transmission. Use a 125ms delay between all device commands vs issue all 5 at once
 *  Jul 05, 2020 v0.0.9 confirm all ccalculation fields are BigDecimal, adjust AC ir cooling codes
 *  Jun 30, 2020 v0.0.8 Fix BigDecimal problem calculating dryPoint and fanPoint
 *  Jun 30, 2020 v0.0.7 Add bool for standard cooling or extended cooling logic
 *							standard Cool mode directly controlled by thermostat
 *							add logic for heat and emergency heat
 *							Attempted setting mode 'mycool' but dashboard hides temperature controls so used input seting.
 *  Jun 28, 2020 v0.0.6 Set the cooling cycle as follows applies when mode is cool and globalMyCool is true
 *					cooling >=cooling set point
 *					drying	>=cooling set point - hysterisis
 *					fan		>=cooling set point - hysterisis*2
 *					off		< cooling set point - hysterisis*2
 *  Jun 28, 2020 v0.0.5 Process HSM arming Status
 *  Jun 28, 2020 v0.0.4	Change pauseExecution to a runIn
 *  Jun 27, 2020 v0.0.3	Support user defined thermostat mode: dry Turn on dry when idle and mode=dry regardless of temperature
 *							Used virtual thermostat command setSupportedThermostatModes adding dry
 *								with string [cool, off, dry, fan, heat, auto, emergency heat] also ajusting settings order on device
 *  						Subscribe to thermostatMode changes
 *							set Fan mode to dry, cool, or off giving clear visual operational indication
 *  Jun 26, 2020 v0.0.2	Delay temperature and coolSetPoint changes or 2 seconds allowing any virtual thermostat operating mode changes to complete
 *						set fan operating mode to dry when using dry mode, otherwise set fan mode to on
 *  Jun 25, 2020 v0.0.1	Use thermostatModeHandler for all IR processing, dont set operating mode to dry
 *  Jun 25, 2020 v0.0.0	Create
