#   Info: Checks the presence of a given MAC thru router and reports changes back to domoticz
#   Add to crontab for recurrent check
#   how to determine encrypted password TPlink, see https://www.home-assistant.io/components/device_tracker.tplink/ 
# Python 3.6
# Customize check(switchid_in_domoticz, "Optional human name for log",presence_status_according_to_router)
# and all credentials and IP addresses
