Disable internet to any device

[pilotak]

That’s exacly why chose Mikrotik due to its flexibility.

1. I use this one and at my friend’s home there is this one where he is using it for the same purpose. But any Mikrotik will be fine
2. It’s generic component for running scripts not just for disabling internet.

Here is the guide in Mikrotik

• Create separate login credentials for HASS

• Create firewall rule: Chain=forward, Src. MAC Address=00:00:00:00:00:00 (select device address), Action=reject, Reject With=icmp admin prohibited after save you will see an id of the rule ie.: 10 (you will use this number in scripts)

• Give your device static IP address in DHCP section ie.: 192.168.0.100

• Create script with name internet_tom_on this will enable firewall rule you created above (it will block new connections), next line is also important as it closes all connections made before enabling firewall rule

/ip firewall filter enable 10
:foreach i in=[/ip firewall connection find where src-address~"^192.168.0.100:.*\$"] do={ /ip firewall connection remove $i }

• Create script with name internet_tom_off

/ip firewall filter disable 10

In HASS config:

script:
internet_tom_on:
    sequence:
      - service: mikrotik.run_script
        data:
          name: internet_tom_on
      - service: input_boolean.turn_on
        data:
          entity_id: input_boolean.internet_tom

  internet_tom_off:
    sequence:
      - service: mikrotik.run_script
        data:
          name: internet_tom_off
      - service: input_boolean.turn_off
        data:
          entity_id: input_boolean.internet_tom

input_boolean:
  internet_tom:

switch:
  - platform: template
    switches:
      internet_tom:
        value_template: "{{ is_state('input_boolean.internet_tom', 'on') }}"
        turn_on:
          service: script.turn_on
          data:
            entity_id: script.internet_tom_on
        turn_off:
          service: script.turn_on
          data:
            entity_id: script.internet_tom_off
