Revesing switch on led lights

Configuration
1

Hello everybody.
I have problem with reversing switch on UI interface.
When I turn on led lights, switch coming back and on few moment turning on. The same sytuation is when i turn leds off. value_template read value of register and my leds slowly ignites during 2,5 sec(change value of register during 2,5 sec). Is it posible to make some delay of read value_template? this is code:

    led3:
      friendly_name: "Led Sala3"
      level_template: "{{ (states('sensor.ledsala3') | int(0) * 1.0) | round(0) | int(0) }}"
      value_template: "{{ states('sensor.ledsala3') | int(0) > 0 }}"
      turn_on:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: 255
      turn_off:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: 0
      set_level:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: "{{ brightness }}"

Try this:

    led3:
      friendly_name: "Led Sala3"
      level_template: "{{ (states('sensor.ledsala3') | int(0) * 1.0) | round(0) | int(0) }}"
      value_template: "{{ states('sensor.ledsala3') | int(0) > 0 }}"
      turn_on:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: 255
        - delay: 1
        - service: homeassistant.update_entity
          entity_id: sensor.ledsala3
      turn_off:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: 0
        - delay: 1
        - service: homeassistant.update_entity
          entity_id: sensor.ledsala3
      set_level:
        - service: modbus.write_register
          data_template:
            hub: "hub1"
            unit: 5
            address: 2
            value: "{{ brightness }}"
        - delay: 1
        - service: homeassistant.update_entity
          entity_id: sensor.ledsala3

You may not need the delays.
