Added an off function to reset the timer, when at least one entity is turned off manually (https://community.home-assistant.io/t/appdaemon-motion-detectionlights-version-1-1/6632)

motion_lights.py

import appdaemon.appapi as appapi
##############################################################################################
# Args:
#
# sensor: binary sensor to use as trigger. several motion detectors are seperated with ,
# entity_on : entity to turn on when detecting motion, can be a light, script, scene or anything else that can be turned on. more lights are sepetated with ,
# entity_off : entity to turn off when detecting motion, can be a light, script or anything else that can be turned off. Can also be a scene which will be turned on. more lights are sepetated with ,
# delay: amount of time after turning on to turn off again. If not specified defaults to 60 seconds.
#
# Release Notes
#
# Version 1.1:
#   Added option for several lights, scripts, scenes (Rene Tode)
#   Added option for several motiondetectors (Rene Tode)
#   Added option to just turn out light after timer ended (Rene Tode)
#   Added controle if timer from motionsensor is longer then the delay (Rene Tode)
#   Changed handlenaming bug (Rene Tode)
#   Changed reset flow (Rene Tode)
# Version 1.0:
#   Initial Version (aimc)
