Here is a logger example:

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 {idx:08X} {device_state=:2i} {key=:2i} {state=:2i} {device=:2i}")
  end

  def button_pressed(cmd, idx)
  	var button = (idx >> 16) & 0xFF
  	var last_state = (idx >> 8) & 0xFF
  	var index = (idx & 0xFF)
    log(f"---: FUNC_BUTTON_PRESSED {button=:2i} {last_state=:2i} {index=:2i}")
  end

  def button_multi_pressed(cmd, idx)
    var press_counter = (idx >> 8) & 0xFF
  	var index = (idx & 0xFF)
    log(f"---: FUNC_BUTTON_MULTI_PRESSED {press_counter=:2i} {index=:2i}")
  end
