Processing KNX Addresses

[AISystem]

This would lead to the possibility of many errors, can't it be done with a resident script that monitors states and processes events? I tried to write something similar, but apparently I don't understand the system's workings very well and it doesn't work for me.

Code:

local function object_exists(obj_address)
  local obj = grp.find(obj_address)
  return obj ~= nil
end

-- table with the addresses of function_one
local function_one = {}
for i = 1, 60 do
  for j = 11, 241, 10 do
    local function_one_address = i .. "/2/" .. j
    if object_exists(function_one_address) then
      function_one[(i - 1) * 24 + (j - 11) / 10 + 1] = function_one_address
    end
  end
end

-- table with the addresses of group_numbers
local group_numbers = {}
for i = 1, 60 do
  for j = 11, 241, 10 do
    local group_numbers_address = i .. "/3/" .. j
    if object_exists(group_numbers_address) then
      group_numbers[(i - 1) * 24 + (j - 11) / 10 + 1] = group_numbers_address
    end
  end
end

-- create client
client = require('localbus').new(0.1)

local function update_group_numbers_for_group(group_number)
  local has_true_function_one = false
  for j, function_one_item in ipairs(function_one) do
    if tonumber(function_one_item:match("(%d+)/2/%d+")) == group_number then
      if grp.getvalue(function_one_item) == 1 then
        has_true_function_one = true
        break
      end
    end
  end

  for j, group_number_item in ipairs(group_numbers) do
    if tonumber(group_number_item:match("(%d+)/3/%d+")) == group_number then
      local current_group_number_state = grp.getvalue(group_number_item)
      if has_true_function_one and current_group_number_state == 1 then
        grp.write(group_number_item, 0)
      elseif not has_true_function_one and current_group_number_state == 0 then
        grp.write(group_number_item, 1)
      end
    end
  end
end

-- set function to handle events from group addresses
client:sethandler('groupwrite', function(event)
  local address = event.dst
  local value = tonumber(event.datahex, 16) or 0

  -- check if the address is in the list of function_one addresses
  for i, function_one_item in ipairs(function_one) do
    if address == function_one_item then
      local group_number = tonumber(function_one_item:match("(%d+)/2/%d+"))
      update_group_numbers_for_group(group_number)
      break
    end
  end
end)

-- start the client for data exchange on the local bus
client:loop(1)
