 *  tvWrangler App
 *  Functions:
 *		Controls on and off for TV, Cable Box, and sound system using a virtual switch displayed on a dashboard
 *           triggering an Ir Blaster
 *      Stops sound system popping by controlling sequence of on and off. Logic copied from replaced RM rules.
 *		Allow 10 seconds for TV to fully turn on before it responds to Off commands
 *		Allow 3 seconds for TV to fully turn off before it responds to On commands
 *      Just to much of a pain doing this with Hubitat Rule Machine
 *
 *		Note: The cable box may to have a 20 second time frame where it wont react to the blaster after a blaster valid command
 *				however it always reacts to manual remote
 *				Cable box is very sensitive to IR blaster's distance and position sometimes refusing to respond
