# This script uses a Pir sensor and a IR diode to turn on a tv when motion is detected.
# It uses time to only turn on tv at daytime. 
# It also has a time out, if no motion is detected for a set period the tv is turned off.
# Another function is to send Mqtt messages when tv is turned on or off.
#
# The software irsend from Lirc is used to send codes.
