Modbus RTU - connection problem if more than one connected device

Good morning,

When I have only one device connected on modbus RTU than everything works fine.
When three of them are connected (the same devices) through Modbus RTU than my entities are unavalable.

What could be the problem?

Code:

modbus:

  - name: hub1

    type: serial

    method: rtu

    port: /dev/ttyUSB0

    baudrate: 19200

    stopbits: 1

    bytesize: 8

    parity: N

    timeout: 30

    delay: 20

    retry_on_empty: true

    close_comm_on_error: false

    retries: 5

    sensors:

      - name: "inv01 org Work state"

        scan_interval: 40

        data_type: int16

        slave: 6

        address: 25288

Code for multiple connections:

modbus:

  - name: hub1

    type: serial

    method: rtu

    port: /dev/ttyUSB0

    baudrate: 19200

    stopbits: 1

    bytesize: 8

    parity: N

    timeout: 10

    delay: 5

    retry_on_empty: true

    close_comm_on_error: false

    retries: 5

    sensors:

      - name: "inv01 org Work state"

        scan_interval: 5

        data_type: int16

        slave: 6

        address: 25288


  - name: hub2

    type: serial

    method: rtu

    port: /dev/ttyUSB1

    baudrate: 19200

    stopbits: 1

    bytesize: 8

    parity: N

    timeout: 10

    delay: 5

    retry_on_empty: true

    close_comm_on_error: false

    retries: 5

    sensors:

      - name: "inv02 org Work state"

        scan_interval: 5

        data_type: int16

        slave: 6

        address: 25288

If you can change slave id. You only need one adapter

hey did u ever figure this out???
