Script LUA for Room Test -some problem with danfoss-

[guantolento]

Hi friends,
iam made some test with 2 bathroom. the situation is the same:

1 danfoss room to read the real temperature
2 danfoss valve one in each bathroom
1 SP virtual to command the 2 danfoss valve SP

i use the SP virtual to setting the temperature ,and this script copy the SP to the danfoss.

Code: Select all

sp1Name    = 'SP Bagni'     --nome set point virtuale zona bagni
spR1       = 23                      --nome valvola fisica 1
spR2       = 82                      --nome valvola fisica 2
T1         = otherdevices[sp1Name]   --lettura temperatura set point virtuale zona bagni
VT1      = tonumber(otherdevices['SP Bagni']) --valore del setpoint virtuale zona bagni

pfx      = '>>> [Temperatura] >>>' --prefisso log Temperatura

commandArray = {}

if devicechanged[sp1Name] then
      commandArray[#commandArray + 1] = {['UpdateDevice']=spR1..'|0|'..tostring(T1)}
      commandArray[#commandArray + 1] = {['UpdateDevice']=spR2..'|0|'..tostring(T1)}
      print (pfx..' SetPoint Modificato / Valore Attuale '..sp1Name..' : '..VT1..'')
   end
return commandArray

if the set point of danfoss or room temperature change start another script to put on or off the boyler.

Code: Select all

tUse      = tonumber(otherdevices['SP Bagno Grande']) --valore del setpoint valvola bagno grande
tDelta    = tonumber(uservariables['T Delta Bagni']) --valore della variabile delta bagni
tAct      = tonumber(otherdevices['T Bagni']) --valore della temperatura letta dal termometro bagno grande
debugger = 0

pfx      = '>>> [Temperatura] >>>' --prefisso log Temperatura

commandArray = {}
    if devicechanged['SP Bagno Grande'] or devicechanged['T Bagni'] then 
        if (tAct < (tUse - tDelta)) and (otherdevices['Accensione Caldaia Bagni'] == 'Off') then
            commandArray['Accensione Caldaia Bagni'] = 'On'
            print (pfx..'T ° Attuale Bagni / T ° Set Bagno Grande: '..tAct..'/'..tUse..' (±'..tDelta..') Richiesta Accensione Caldaia Bagni')
        elseif (tAct > (tUse + tDelta)) and (otherdevices['Accensione Caldaia Bagni'] == 'On') then
            commandArray['Accensione Caldaia Bagni'] = 'Off'
            print (pfx..'T ° Attuale Bagni / T ° Set Bagno Grande: '..tAct..'/'..tUse..' (±'..tDelta..') Richiesta Spegnimento Caldaia Bagni')
        else
            if debugger == 1 then
                print ('>>> [Temperatura] NTD >>> T ° Attuale Bagni / T ° Set Bagno Grande: '..tAct..'/'..tUse..' (±'..tDelta..') Nessuna Azione da intraprendere ['..otherdevices['T Bagni']..']')
            end
        end
    end
    return commandArray

in apparence the script work ok, but from the log i view some problem. here the log:

in red the issue. in 1 second the system pull off and on the boyler. i don't so why but for a moment the value of SP Bagno Grande is read as 18 but instead is at 23. 18 is the value before the change. why this ????
another question, why sometimes the Virtual SP goes in red but work of with schedule ? it's normal ?
