How to set packet size for Ping

[placid surge]

Is it somehow possible to set the packet size for the Ping integration? I have intermittent problems with MTU size between sites and it will be very useful to be able to ping with two packet sizes. This would be the -s option for the Ping command.

If it's not documented (and I don't see it), probably not possible.

instead of using the ping integration you could build your own ping sensor with the shell_command integration which would allow you to call a ping with any paramaters you like and capture the response.

another option might be to use uptime kuma addon, i think you can specify size on that but i am not sure i havent used it that much and not at all for a while

Thanks - I'll check this out. If I don't have to write scripts, it will be a win 🙂

Look like shell and scripts for me..

OK it works.

Maybe this helps someone:
In configuration.yaml:

shell_command:
  ping_that_ip: ping [the ip] -c 5 -s 1500

You need a helper:

input_number.that_ip_big_mtu_ping

In Automations:

id: '[your id]'
alias: Ping A Big MTU

  - trigger: time_pattern
    seconds: '60'
