grp.create() - tomnord - 02.02.2024

I'm trying to figure out how to generate a series of viritual adresses. example:

room_nr = {name=, datatype=, }
functions =

etc...

I want GA's to be named something like this: "room_nr""function"

i guess I need a for loop, based on room_nr, but how do I separate the different roomnumbers in the table?
It's most likely easy, brain is in weekend mode Smile

Use this as a starting point:

Code:
for i = 1, 10 do

  name = 'room ' .. i

  log(name)

end

RE: grp.create() - tomnord - 12.02.2024

What is the best way, when using grp.create, to check if the GA is allready created? I'm thinking of making a dynamic script, so that when I add new GA's and tag them correctly the script will generate new virtual GA's.

RE: grp.create() - admin - 12.02.2024

You can use grp.find().

RE: grp.create() - tomnord - 12.02.2024

Regarding this, and the funcion string.gsub() my pattern is '_PV' but i also have some GA's named '_PV3'. is there any way to make this function to apply only with _PV and not _PV3?

RE: grp.create() - admin - 12.02.2024

If your string ends with _PV then you can use _PV$ regular expression. See this for more info: https://www.lua.org/manual/5.1/manual.html#5.4.1

I use function block like this when automatically generating addresses in my programs...

Code:
--**********CREATE GROUP ADDRESSES******************

function createga(groupaddress,datatype,name)

  exist = grp.alias(groupaddress)

  if exist == nil then

    address = grp.create({

    datatype = datatype,

    address = groupaddress,

    name = name,

    comment = 'Automatically created object',

    units = '',

    tags = { },

    })

  end

end

On some systems I use user script where I put all needed group addresses (so they all are on the same file and it's quite easy to change them)..

User script (HEATING_config):

Code:
Main_GA = '33'

group_address_for_frontend_update = '/0/0'        --If any modifications on values or chart must be updated, this variable is used.

group_address_for_backend_update = '/0/1'        --If any modifications on values or data file must be updated, this variable is used.

Scheduled/Resident/Event script:

Code:
require('user.HEATING_config')

createga( Main_GA .. group_address_for_backend_update, dt.bool,'HEATING - Update backend')

createga( Main_GA .. group_address_for_frontend_update, dt.bool,'HEATING - Update frontend')

--DO SOMETHING

Hope this helps...

Thanks guys. I'll do some testing

RE: grp.create() - victor.back - 12.04.2024

Hi I have a function in a script for creating the necessarily groupadresses. But in this script it´s not creating the adresses, can I ask if someone can see what can be the issue?

Code:
-- Skapa nödvändiga gruppadresser

local function skapaGruppadresser()

    local maxZoner = 25  -- Antagande att det finns max 25 zoner

    for i = 100, 121 do

        -- Adresser och namn för zonerna

        local varaktighetAddress = '40/2/' .. i

        local dagligVaraktighetAddress = '40/4/' .. i

        local varaktighetName = 'Varaktighet Zon ' .. i

        local dagligVaraktighetName = 'Daglig Varaktighet Zon ' .. i

        -- Skapa adress för varaktighet om den inte redan finns

        if not grp.find(varaktighetAddress) then

            grp.create({datatype = 'dt.text', address = varaktighetAddress, name = varaktighetName})

        end

        -- Skapa adress för daglig varaktighet om den inte redan finns

        if not grp.find(dagligVaraktighetAddress) then

            grp.create({datatype = 'dt.text', address = dagligVaraktighetAddress, name = dagligVaraktighetName})

        end

    end

    -- Skapa återställningsflagga om den inte redan finns

    local resetAddress = '40/3/0'

    if not grp.find(resetAddress) then

        grp.create({datatype = 'dt.bool', address = resetAddress, name = 'Återställningsflagga'})

    end

end

skapaGruppadresser()

datatype field should be either dt.text (without quotes) or 'text'
