Event address changed

[Domoticatorino]

Hi,
I surf on the forum without success.

I have to create an event script and I have to manage the value only if it is changed. 

Code:

value = event.getvalue()

    if value == true then
    require("user.telegram")
    message = 'ALARM'
    res, err = telegram(message)
    log(res, err)
    else
  require("user.telegram")
    message = 'NOT ALARM'
    res, err = telegram(message)
    log(res, err)
    end

The problem is that everytime there's a KNX telegram sending I receive a message. Which command can I use please?

Thanks.

BR
