Here is some example code to dump the values of any_key():

class AnyKeyLogger
  def init()
    tasmota.add_driver(self)
  end

  def any_key(cmd, idx)
    #device_save << 24 | key << 16 | state << 8 | device
    var device_state = (idx >> 24) & 0xFF
    var key = (idx >> 16) & 0xFF
    var state = (idx >> 8) & 0xFF
    var device = idx & 0xff
    log(f"---: FUNC_ANY_KEY {device_state=:2i} {key=:2i} {state=:2i} {device=:2i}")
  end
end
