RTU OVER TCP Unable to decode response

HA modbus RTU OVER TCP connect ESP_easy ser2net, can’t recieve full data bytes, NO CRC BYTES. As the modbus protcol ,the recieve datas should be 9,but in fact only 7


My configration code is below.

modbus:
  - name: "SMA"
    type: rtuovertcp
    host: 192.168.0.124
    port: 502
    delay: 5
    timeout: 5
    sensors:
      - name: IM1281B
        unit_of_measurement: ℃
        slave: 2
        address: 0078
        count: 1
        data_type: uint
        scale: 0.01
        precision: 2
        scan_interval: 30

when i use the modbusscan tool to test the device, the datas are full and correct ,but the modbusscan tool “Valid Slave Responses” is 0.

when i use the modbusPoll tool to test the device, the datas are full and correct ,but the modbusPoll tool shows “Checksum error”.

I found the reason . My power meter(IM1281B) is not a standard modbus protocol device. In it’s protocol, a register has 4 bytes datas, but standard modbus protocol only has 2 bytes datas in a register.
