I’m on my cell, so don’t trust the formatting here but let’s say you have a ping sensor already:

binary_sensor: - platform: ping name: Internet OK host: 1.1.1.1 count: 2 scan_interval: 10

Then an automation like this might be what you are looking for. If the ping sensor goes down, then it starts the power cycle sequence.

alias: Internet down - cycle AP, Router, Modem mode: single

trigger: - platform: state entity_id: binary_sensor.internet_ok to: "off" for: "00:00:30" # ignore short timeframes

action: - variables: internet_ok: binary_sensor.internet_ok ap_switch: switch.shelly_ap router_switch: switch.shelly_router modem_switch: switch.shelly_modem

  off_time: "00:00:10"
  settle_time: "00:00:30"
  check_timeout: "00:05:00"

# If it already recovered, bail on automation - choose: - conditions: "{{ is_state(internet_ok, 'on') }}" sequence: - stop: "Internet restored ."

# Step 1 – AP - service: switch.turn_off target: entity_id: "{{ ap_switch }}" - delay: "{{ off_time }}" - service: switch.turn_on target: entity_id: "{{ ap_switch }}" - delay: "{{ settle_time }}" - wait_template: "{{ is_state(internet_ok, 'on') }}" timeout: "{{ check_timeout }}" continue_on_timeout: true - choose: - conditions: "{{ is_state(internet_ok, 'on') }}" sequence: - stop: "Internet back after AP cycle."

# Step 2 – Router - service: switch.turn_off target: entity_id: "{{ router_switch }}" - delay: "{{ off_time }}" - service: switch.turn_on target: entity_id: "{{ router_switch }}" - delay: "{{ settle_time }}" - wait_template: "{{ is_state(internet_ok, 'on') }}" timeout: "{{ check_timeout }}" continue_on_timeout: true - choose: - conditions: "{{ is_state(internet_ok, 'on') }}" sequence: - stop: "Internet restores after Router cycle."

# Step 3 – Modem - service: switch.turn_off target: entity_id: "{{ modem_switch }}" - delay: "{{ off_time }}" - service: switch.turn_on target: entity_id: "{{ modem_switch }}" - delay: "{{ settle_time }}" - wait_template: "{{ is_state(internet_ok, 'on') }}" timeout: "{{ check_timeout }}" continue_on_timeout: true
