Is a modbus digital input fast enough to detect a DoubleClick?

Hello

I wonder if i will use in my project a Modbus input it will be enough quick (responsive) to use for DoubleClick event?

Thank you

It looks like sofar working (if limiting number of modbus devices).

I using the following setup:

uart:
  - id: mbus_fast
    tx_pin: 17
    rx_pin: 16
    baud_rate: 115200 #115200
    stop_bits: 1

  - id: mbus
    tx_pin: 1 
    rx_pin: 3
    baud_rate: 9600 #9600
    stop_bits: 1


modbus:
  - id: ga_f_eloszto_modbus1
    uart_id: mbus

  - id: ga_f_eloszto_modbus2
    uart_id: mbus_fast
    
modbus_controller:
  - id: ga_f_eloszto_mbsl32di_1
    ## the Modbus device addr
    address: 10
    modbus_id: ga_f_eloszto_modbus2
    setup_priority: -20
    update_interval: 0.08s

  - id: ga_f_eloszto_mbsl32di_2
    ## the Modbus device addr
    address: 11
    modbus_id: ga_f_eloszto_modbus2
    setup_priority: -20
    update_interval: 0.08s
    #command_throttle: 100ms

  - id: ga_f_eloszto_24c3d32
    ## the Modbus device addr
    address: 30
    modbus_id: ga_f_eloszto_modbus1
    setup_priority: -10
    #update_interval: 1s

Please note even if i add one new device with a very slow update interval “15s” it became unstable.

Also i force to read 4 Byte intsed of 2 ( response_size ) in order to limit a number of transaction on the bus:

- platform: modbus_controller
  internal: true
  modbus_controller_id: ga_f_eloszto_mbsl32di_1
  name: ga_f_eloszto_1_I01
  id: ga_f_eloszto_1_I01
  register_type: holding
  response_size: 4 # Reading 4 byte to cache the other registry content (only 2read possible in this rate on the fast_modebus wire)
  address: 0 #0x40001
  bitmask: 0x2
  on_multi_click:
    - timing:
        - ON for 40ms to 400ms
        - OFF for 40ms to 400ms
        - ON for 40ms to 400ms
        - OFF for at least 430ms
      then:
        - text_sensor.template.publish:
            id: ga_f_eloszto_kiseloszoba_Kapcsolo_KEYS
            state: !lambda 'return "double_01";'
    - timing:
        - ON for 40ms to 400ms
        - OFF for 40ms to 400ms
        - ON for 40ms to 400ms
        - OFF for 40ms to 400ms
        - ON for 40ms to 400ms
        - OFF for at least 50ms
      then:
        - text_sensor.template.publish:
            id: ga_f_eloszto_kiseloszoba_Kapcsolo_KEYS
            state: !lambda 'return "triple_01";'
