# Pi-hole HA Sync - Mirror blocking state across DNS nodes
#  Keep Pi-hole blocking on docker_10 and docker_14 in lockstep.
# -------------------------------------------------------------------
# Notes: Uses switch.pi_hole + switch.pi_hole_2 from the Pi-hole integration.
# Notes: Auto re-enables Pi-hole after 60 minutes of being off.
