Processing KNX Addresses

[AISystem]

I generally don't understand something. I tried using the advice you gave me, but apparently I'm not using them correctly.

Code:

local inputgroup = {}
local groupobjects = {}

for i = 1, 60 do
  groupobjects[i] = {}

  for j = 11, 241, 10 do
    local addr = i .. "/2/" .. j
    local status, value = pcall(grp.getvalue, addr)

    if status and value ~= nil then
      inputgroup[addr] = i
      groupobjects[i][addr] = value
    end
  end
end

local function updategroup(group)
  local objects = groupobjects[group]
  local groupon = false

  for addr, value in pairs(objects) do
    if value then
      groupon = true
      break
    end
  end

  log(groupon)

  local controlAddress = group .. '/2/0'
  local isControlEnabled = grp.getvalue(controlAddress)

  if isControlEnabled and isControlEnabled ~= nil then
    local changeState = not groupon

    for i = 11, 161, 10 do
      local address3 = group .. '/3/' .. i
      local address5 = group .. '/5/' .. (i + 7)

      if pcall(grp.getvalue, address3) then
        grp.checkwrite(address3, changeState)
      end

      if pcall(grp.getvalue, address5) then
        grp.checkwrite(address5, changeState)
      end
    end
  end
end


local function onStateChange(event)
  local addr = event.dst
  local group = inputgroup[addr]

  if group then
    local value = tonumber(event.datahex, 16) ~= 0
    groupobjects[group][addr] = value
    updategroup(group)
  end
end


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

if event then
  for group = 1, 60 do
    for device = 11, 161, 10 do
      local address = group .. '/2/' .. device
      if pcall(grp.getvalue, address) then
        event.register(address, onStateChange, 'groupwrite')
      end
    end
  end
else
  log('event not available')
end

while true do
  client:loop(1)
end
