Scripting

[mariosp]

Explain exactly what do you want this script to do.

so its a littlebit complicated.
I have underfloor heating i want the pwm valves to not close and i want to change the %of the opening valve i want if the actual temperature 
is higher than then setpoint to write to the group address of the heating actuator the setpoint - the offset that my client will set 
but if the actual temperature is lower than the set i want to write to  group address of the heating actuator the actual temperature so it will open more if need it heres is the script that i end up. Thank you in advance! 

Code:

if event.getvalue() then
-- actual temperature of room1
  local actual_temp1 = grp.getvalue('12/0/5')
  -- group address of the heating actuator for temperature
  local fake_temp_addr1 = '3/3/1'
-- virtual group address that i created for mosaic
  local offsetvalue = grp.getvalue('32/1/69')
-- master setpoint for all rooms    
  local value_temp = grp.getvalue('12/1/0')
  --setpoint of room
  local value_temp1 = grp.getvalue('3/1/1')
-- for mosaic because that i made it with rotary dimmer
  local offset = value_temp - offsetvalue * 0.01


if actual_temp1 >= value_temp or  value_temp1
  then
grp.write(fake_temp_addr1,offset)
 
else
  grp.write(fake_temp_addr1,actual_temp1)
