Not sure about that, though there will be a new function grp.checkvalue(alias, value [, delta]) which tells whether the value should be sent or not. It can be used for your task (you can create your own wrapper function and put it into common functions):
Code:
value = 50
if grp.checkvalue('1/4/1', value) then
grp.write('1/2/1', value)
end
