hi,
in my house i have this configuration:
- SP room sensor A ( need command 2 SP Valve)
- SP room sensor B ( need command 2 SP Valve)
- SP room sensor C ( need command 3 SP Valve)
iam newbe, i need with LUA script every times change the SP room sensor A, change the value SP to 2 valve. with this metod i can schedulate only 3 device instead 7. i have another problem. i think must use a variables.
example SP room sensor A changed from 16 to 18
the SP of valve A must changed from 16 to 18
the SP of valve B must changed from 16.5 to 18.5 (the gap is alway +0.5 because the radiators is more high and the termostatic valve is at 1.8mt instead 1.10)
someone can help me ?

i take some test for modify a set point with a test script:
Code: Select all
commandArray = {}
if devicechanged['Cucina Pensili - S1'] then
if (otherdevices['Cucina Pensili - S1'] == 'On') then
commandArray['SetSetpoint:82']='22'
commandArray['SetSetpoint:23']='22'
commandArray['Cameretta Comò - S1'] = 'On'
elseif (otherdevices['Cucina Pensili - S1'] == 'Off') then
commandArray['SetSetpoint:82']='16'
commandArray['SetSetpoint:23']='16'
commandArray['Cameretta Comò - S1'] = 'Off'
end
end
return commandArray
but the 2 setpoint don't work . why ?

There's a function for this in my pass2php script.
Check the __verwarming.php file on my Github.
I set my valves x degrees lower/higher depending on the difference between room temperature and room setpoint.

Hi at all,
actually i use this LUA script to copy the value of SP Camere (Virtual SP beacuse the fisic SP Danfoss Room don't work) to 2 fisic SP Valves Danfoss.
Code: Select all
sp2Name = 'SP Camere' --nome del set point virtuale zona camere
spR3 = 25 --nome valvola fisica 3
spR4 = 30 --nome valvola fisica 4
T2 = otherdevices[sp2Name] --lettura temperatura set point virtuale zona camere
VT2 = tonumber(otherdevices['SP Camere']) --valore del set point virtuale zona camere
pfx = '>>> [Temperatura] >>>' --prefisso log Temperatura
commandArray = {}
if devicechanged[sp2Name] then
commandArray[#commandArray + 1] = {['UpdateDevice']=spR3..'|0|'..tostring(T2)}
commandArray[#commandArray + 1] = {['UpdateDevice']=spR4..'|0|'..tostring(tonumber(T2)+1.5)}
print (pfx..' SetPoint Modificato / Valore Attuale '..sp2Name..' : '..VT2..'')
end
return commandArray
the first valve has the same SP, the second has SP + 1.5. i use this from 1 week and work ok.
