1-wire keyfob and reader

[admin]

Here's a basic example, create a resident script with sleep time = 0. os.sleep at the end tells how often the 1-Wire bus is polled for new devices. Can you explain what kind of task do you have, some kind of access / door control or similar? I can provide a better example if the details are known

Code:

if not ow then
  require('ow')
  
  -- list of allowed devices
  allowed = { '3A.B9901C000000' }
end

-- list of connected devices
visible = ow.list(true)

-- find if any allowed devices are present
for _, id1 in ipairs(visible) do
  for _, id2 in ipairs(allowed) do
    if id1 == id2 then
      -- do something here
    end
  end
end

os.sleep(0.5)
