Webhooks to change command_line switch state

Configuration
1

in my configuration i have command_line switch looking like this to use some external device:

switch:
  - platform: command_line
    switches:
      jadalnia:
        command_on: "curl 'http://ip/relay?something'1"
        command_off: "curl 'http://ip/relay?something2'"
        command_state: "curl 'http://ip/relay?something3'"
        value_template: '{{ value == "1" }}'
    scan_interval: 5

It works fine, and state of switch refreshes correctly.

I want to have as small delay as possible in case device will be switched in other way (not by HA) but to avoid unnecessary traffic every 5 seconds in my network I wanted to change scan_interval into some webhook to HA to be called by this device (it can do that) to change state of command_line switch entity. This would reduce traffic in my network. I was trying to find solution but with no success.

Yes, we need a option for manual scan via webhook or something else, it is more efficient and energy-saving than scan every xx seconds.

Automation could do this by create 1 helper with 4 tasks, but it is not tidy and will cause on-off loop sometimes…
