/**
PI Talk media GPIO controler
Hubitat driver to connect to rasbery pi and talk
capability 
Notification,Chime,Alarm,MusicPlayer,SpeechSynthesis,buton,Presence,Temp,Volts
=====================================================================================
Reads text on the pi or you can play any mp3 file on your pi through pi speakers.

Requires other packages in this directory be installed on the pi under a php webserver.
to take the commands.

v1.0  09/08/2021 

-------------------------------------------------
you need to install these files on your pi 
talk.php <-- this driver talks to this file
temp.php <-- this file post back to this driver
input-scan.php <-- Safe loading of get and post
talk.sh  <-- this runs in a loop to take action
temp-chart.sh <-- Draws a png temp chart in /images 

install-talk.sh <-- Installs extra programs on pi
