Use Apple Airtag instead of Rfid tag

You need to create a group objects that controls your door lock (the group name is 'open' in this example), then add the id (the variable open_lock is for this purposes), then each time you will scan the device it will opens the door. In the same style you can add more different id for different group objects. (After changes do not forget to disable/enable the resident script)

Code:

require('ow')

function findDifferences(list, prev_list)
  local new_ids = {}
  local removed_ids = {}

  -- Check for new IDs
  if list then
    for id, _ in pairs(list) do
      if not prev_list or not prev_list[id] then
        table.insert(new_ids, id)
      end
    end
  end

  -- Check for removed IDs
  if prev_list then
    for id, _ in pairs(prev_list) do
      if not list[id] then
        table.insert(removed_ids, id)
      end
    end
  end

  return new_ids, removed_ids
end

local temperat_sens = "28.DBCA83050000"
local open_lock = "01.CE6371690000" -- your id to open door lock


list = ow.list()

local new_ids, removed_ids = findDifferences(list, prev_list)

if #new_ids > 0 then
  log("New IDs:")
  for _, id in ipairs(new_ids) do
    log(id, list[id])
    if list[id] == temperat_sens then
      grp.write('temperat', true)
    elseif list[id] == open_lock then
      grp.write('open', true) -- your object that controls door lock
    end
  end
end

if #removed_ids > 0 then
  log("Removed IDs:")
  for _, id in ipairs(removed_ids) do
    log(id, prev_list[id])
  end
end

prev_list = list
