scripting knx

[ALEJANDRO]

Good morning,

I'm having a problem with the functions and I don't know how to solve it.

Here's the problem:

I currently have three logic machines taking KNX data from temperature, humidity, and CO2 sensors. I need them to calculate the average temperature, CO2, and humidity. But I only want to calculate this for the sensors located in rented properties.

I have the following variables.


Rented or non-rented status of 27 dwellings in group addresses from 2/0/176 to 2/0/202:

- Rented = 1

- Non-rented = 0
Temperature values delivered by each dwelling sensor:

'0/0/11','0/0/27','0/0/43','0/0/59','0/0/75','0/0/91','0/0/107',

'0/0/123','0/0/139','0/0/155','0/0/171','0/0/187','0/0/203',

'0/0/219','0/0/235','0/0/251',

'0/1/11','0/1/27','0/1/43','0/1/59','0/1/75','0/1/91','0/1/107',

'0/1/123','0/1/139','0/1/155','0/1/171'

Variable where the average building temperature will be stored:

2/0/164

And now I'll show you the code I wrote:









-- Direcciones de estado de las 27 viviendas (0=libre, 1=alquilada, 2=mantenimiento, 3=ocupada)
local estados = {}
for i = 1, 27 do
    estados[i] = '2/0/' .. (175 + i)  -- 176 → 202
end

-- Direcciones de temperatura individuales
local direcciones_temp = {
    '0/0/11','0/0/27','0/0/43','0/0/59','0/0/75','0/0/91','0/0/107',
    '0/0/123','0/0/139','0/0/155','0/0/171','0/0/187','0/0/203',
    '0/0/219','0/0/235','0/0/251',
    '0/1/11','0/1/27','0/1/43','0/1/59','0/1/75','0/1/91','0/1/107',
    '0/1/123','0/1/139','0/1/155','0/1/171'
}

-- Dirección donde guardar la temperatura media
local destino1 = '2/0/164'

-- Rango válido de temperaturas
local min_temp = -20
local max_temp = 60

-- Intervalo de espera: 5 minutos (300 segundos)
local INTERVALO = 300


-- ============================================================
-- BUCLE PRINCIPAL (TU MISMO CÓDIGO, REPITIÉNDOSE PARA SIEMPRE)
-- ============================================================

while true do

    local suma = 0
    local contador = 0

    -- Recorrer las 27 viviendas
    for i = 1, 27 do
        local estado = grp.getvalue(estados[i])
        local valor = grp.getvalue(direcciones_temp[i])

        -- Solo usar temperatura si la vivienda está alquilada
        if estado == 1 then
            if valor ~= nil and type(valor) == "number" then
                if valor >= min_temp and valor <= max_temp then
                    suma = suma + valor
                    contador = contador + 1
                else
                    log("Temperatura fuera de rango en " .. direcciones_temp[i] .. ": " .. tostring(valor))
                end
            else
                log("Valor de temperatura inválido o nulo en " .. direcciones_temp[i])
            end
        end
    end

    -- Guardar la media si hay datos válidos
    if contador > 0 then
        local media = suma / contador
        grp.write(destino1, media)
        log("Temperatura media (solo alquilados) actualizada en " .. destino1 .. ": " .. media)
    else
        log("No hay viviendas alquiladas con temperatura válida para calcular la media")
    end

    -- Esperar 5 minutos antes de repetir
    os.sleep(INTERVALO)

end





Lo he intentado por todos los medios posibles y no me  calcula la temperatura media y cuando lo hace satura la memoria de la logic machine.

What script type are you using? The correct approach is to use a scheduled script that runs every 5 minutes and remove the while loop and os.sleep at the end.

What is the data type of rented status object. Is it boolean or 1 byte?

Buenas tardes,

Estaba ocupado con la construcción. Adjunto fotos del tipo de datos utilizado para los estados de las propiedades; es la versión 7.2.

En cuanto al script, se trata de un script basado en eventos.

[admin]

It can't be an event script. Make a scheduled script as suggested earlier.

I haven't tried yet to create scripts scheduled at specific times and dates; I'm worried that the code won't understand that it needs to update the average temperature every 5 or 10 minutes.
