How to get value from an object?

[Daniel]

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)
