How to get value from an object?

[sck]

Yes, when you use event script and event.getvalue() then you will get last value from the object which triggers the event script. In your case is a 1bit object. If you want the dimming value do the same for 3bit dimming object.  Alternatively you can do value = grp.getvalue('1/1/1') but this is will be checked each time a script is triggered(in case of event)

Thank you for your prompt response but I am afraid I don´t get it. On the one hand, you mention doing the same for 3bit dimming objects but I don´t know what you are referring to. 
On the other hand, you talk about getting the value from 1/1/1 which I also don´t understand since when doing that I only get true or false
