Time delay command: suggestion

Wed, 13 May 2026 07:08:50 +0000

Hi,
I am preparing a logic to manage an heating system.

Considering that I have to set TOF or TON (set to ON or OFF a grp address only if the condition is valid for more than 5 or 10 minutes).

Using "os.delay" for minutes is not suggested as you know.

Which is the best approach to manage it?

Thanks.

Hi everybody,
with this script I would like to send a notification (by mail) if an alarm sensor (tag alarm) goes to true but only if this sensor own to a sector (tag "area_x_sector_x) is armed.
The sensor has a second tag "sensore_area_x_settore_x) in order to verify if it owns to the sector armed.
It does not work because the tag value is empty.

How can be possible? Is it possible to use 2 tags for a grp address?

Thanks.

kWh meter, a ZIV E0090 P1 port

Modbus help

Wed, 22 Apr 2026 09:35:37 +0000

When using LM5 for Modbus communication, if the resident script queries the register status while the event script is writing to the register, it may not be possible to write to the register. How can this be better resolved?

Hello everyone,

we have a customer that has this Videoplayer

This device has a RS232 interface to control it.
Is there a way to connect and control it with the Logicmachine via RS232 ?

Thanks
Kind regards

Blink Output LM5R

Mon, 20 Apr 2026 07:47:12 +0000

Hi

I need a digital output from the reactor that makes a lamp flash. Is it possible to create a reusable function that does this, passing it the flashing time?

Thank you very much.

TAG filtering in script

Fri, 17 Apr 2026 14:09:46 +0000

Good morning

I've already created applications that, in the event of an alarm, send emails to a specific email list. Now the client is asking me if I can differentiate the emails sent based on the alarm. I was wondering if it's possible to use tags to differentiate who gets emails or text messages. How can I use tags?

Thanks

API Datadis

Thu, 16 Apr 2026 11:32:11 +0000

Hola
Necesito integrar la API de Datadis (https://datadis.es/home), que permite acceder a los datos de consumo eléctrico de los contadores inteligentes en España, en una aplicación Wiser para KNX.

Datadis requiere la creación de un nombre de usuario y una contraseña, así como un token de acceso.

¿Cuál es la mejor manera de hacerlo?

Gracias.

Lua script connecting to own KNXnet/IP tunnelling server — status 8

Wed, 08 Apr 2026 13:39:34 +0000

I am trying to send individual address KNX property write/read frames from a Lua event script on LM5 (IP Routing mode, KNX address 2.1.5). The script opens a UDP socket and sends a CONNECT_REQUEST . The CONNECT_RESPONSE always returns status 0x08 (which I assume is no more connections). This happens even after a reboot with no other clients connected. ETS connects successfully using NAT mode. Is it possible for a Lua script to connect to the LM's own tunnelling server, and if so what is the correct approach?

scripting knx

Wed, 08 Apr 2026 06:28:37 +0000

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:

Code:
-- 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.

Object not shown in Objects' tab

Sun, 05 Apr 2026 20:46:08 +0000

I have an object from ETS 31/0/45 but this object is not displayed in the Object tab. Also I can not add another object with the same address.
If I find ID thru

Code:
local obj = grp.find('31/0/45')

if obj then

  for k,v in pairs(obj) do

    log(k .. ' = ' .. tostring(v))

  end

else

  log('not found')

end

and delete this object with "grp.delete(id)", and then add it manually, the operation is successful but it again dissapears from the list.

Could you advice?

Thanks

get version of installed app

Sat, 21 Mar 2026 13:33:37 +0000

Hello everyone,

I’m trying to find out how to determine the version of an installed application, basically the information that appears in the control file.

I don’t know whether it’s stored in a database or in a file somewhere.

Thanks for the help.

Syslog differences between Resident and Event Scripts

Thu, 12 Mar 2026 20:59:59 +0000

I have the exact same Syslog set up in my Resident and Event Scripts - the Resident Scripts Syslog works, however the Event scripts doesnt

The syslog set up that works in Resident is

local socket = require("socket")

-------------------------------------------------
-- SYSLOG CONFIG
-------------------------------------------------

local SYSLOG_HOST = "192.168.1.51"
local SYSLOG_PORT = 1514

local HOSTNAME = "logicmachine"
local APPNAME = "solar-master"

local LOG_INTERVAL = 60 -- seconds

-------------------------------------------------
-- PERSISTENT UDP SOCKET
-------------------------------------------------

storage.syslog_socket = storage.syslog_socket or socket.udp()

local udp = storage.syslog_socket
udpettimeout(0)

-------------------------------------------------
-- RFC5424 TIMESTAMP
-------------------------------------------------

local function rfc5424_time()

local now = os.time()
local utc = os.time(os.date("!*t", now))
local offset = os.difftime(now, utc)

local sign = "+"
if offset < 0 then sign = "-" end

offset = math.abs(offset)

local hours = math.floor(offset / 3600)
local mins = math.floor((offset % 3600) / 60)

return os.date("%Y-%m-%dT%H:%M:%S") ..
string.format("%s%02d:%02d", sign, hours, mins)

end

-------------------------------------------------
-- SYSLOG SENDER
-------------------------------------------------

local function slog(fields)

local timestamp = rfc5424_time()

local msg = "<14>1 "..timestamp.." "..HOSTNAME.." "..APPNAME.." - - - "..fields

udpendto(msg, SYSLOG_HOST, SYSLOG_PORT)

end

What needs to change for an Event Script to behave the same way and allow for logging to an external syslog server?

Thanks
