I am using a script to do or and and using the tags, the script changes the value of the command address correctly, but it does not change the answer, if instead I command address directly from the LM the answer changes me, what can be, already happened to others?
A thousand thanks

A thousand thanks Sorry this is the script
Code: -- POSSIBILITA DI FARE AND , OR , O MEDIE
-- ASSEGNANDO TAG PER IDENTIFICARE OPERANDI E METTERE USCITA SU INDIRIZZO DI GRUPPO
if not client then
-- each group has 3 fields:
-- tag - status object tag
-- output - status output object
-- mode - calculate mode (and/or/avg)
groups = {
{ tag = 'OR1', output = '5/0/1', mode = 'or' },
{ tag = 'OR2', output = '5/0/8', mode = 'or' },
{ tag = 'OR3', output = '5/0/3', mode = 'or' },

}
-- time to wait between last telegram from any status in group and update

-- object value cache

-- object datatype cache

-- send update only when value changes
grp.checkupdate = function(alias, value)

This should be resident script and it only send value on change not each time.
