Something like 1/1/203 - input1, 1/2/203 - input2, 3/2/203 - output.

Another option is to tag objects with multiple tags (something like "input", "room_1_203") and find other objects using these tag. Or you can create a lookup table with all addresses that the script will use to find input/output objects.

(13.04.2022, 11:21)admin Wrote: Here's a solution with a lookup table. All input objects should have a common tag to which an event script is attached. Fill the addrlist table with group addresses as needed. Each entry is a single room (input 1/2 + output).

The script finds the second input based on the group address that triggered the script and writes the maximum between two inputs to the output object.

Code:

addrlist = {
  {
    input1 = '1/1/1',
    input2 = '1/1/2',
    output = '1/1/3',
  },
  {
    input1 = '1/1/4',
    input2 = '1/1/5',
    output = '1/1/6',
  },
  {
    input1 = '1/2/4',
    input2 = '1/2/5',
    output = '1/2/6',
  },
}

for _, addrs in ipairs(addrlist) do
  if event.dst == addrs.input1 then
    altinput = addrs.input2
    output = addrs.output
    break
  elseif event.dst == addrs.input2 then
    altinput = addrs.input1
    output = addrs.output
    break
  end
end

if altinput and output then
  value1 = event.getvalue()
  value2 = grp.getvalue(altinput)

  grp.checkwrite(output, math.max(value1, value2))
end
