Hello guys i want your help with a script.
we have underfloor heating and pwm valves and i need the LM  to send a value (3%) to the heating if the value of the valve Is < 3% 
every 30 minutes. 
can anyone help me with the script ?

Do you need this to happen instantly or a script which runs every 30 min is fine to check the status and update?

i want to happend  instantly..
i made a event base script  base on the valve group address

 if (0) then
value = 6
  sleep(40)
    grp.write('4/1/1', value)
end


but lm send many times the value with result to overload the tp

Use this:

Code:

value = event.getvalue()
minvalue = 3

if value < minvalue then
  grp.write(event.dst, minvalue)
end

Use this:

Code:

value = event.getvalue()
minvalue = 3

if value < minvalue then
  grp.write(event.dst, minvalue)
end

Thank you it works perfectly !!!
