ZWaveJS - PING dead nodes

##############################################################################
# Automation requirements: all z-wave devices should contain
# enabled 'sensor.*_node_status' and 'button.*_ping' entities
# This automation is pressing ping button up to 5 times every 15 seconds until
# a node becomes alive. The automation is queued to avoid zwave network traffic jam.

# Template to collect _node_status entities for non-battery powered z-wave devices
# Pinging battery powered devices repeatedly is not good idea as they need to be woken up.
# The output of this temlate can be used in the trigger definition of the automation above.
# Using the template in the trigger or in a template sensor is not recommended because
# it will be executed on each state change of each z-wave entity causing resource loss.
