Modbus sensor with multiple registers broken after update to 2023.8.2

Configuration
1

Hello!

After updating from version 2023.8.1 to 2023.8.2, my modbus sensors stopped working.

There is a release note regarding modbus for version 2023.8.2, and I think this change has something to do with it, but I don’t understand how to make it work again. Anyone who knows?

This is my config that has been working up until now

- name: Input_Sensor_Register_41_Plus
  unique_id: input_sensor_register_41_plus
  slave: 1
  address: 40
  slave_count: 5 # count - 1
  input_type: input
  count: 6 # total number of registers to read
  scale: 1
  offset: 0
  precision: 0
  data_type: int16
  scan_interval: 15

- name: Holding_Sensor_Register_1_Plus
  unique_id: holding_sensor_register_1_plus
  slave: 1
  address: 0
  slave_count: 98 # count - 1
  input_type: holding
  count: 99 # total number of registers to read
  scale: 1
  offset: 0
  precision: 0
  data_type: int16
  scan_interval: 15

EDIT: Tried going back to version 2023.8.1 and then all the sensors work again, so it’s definitely something in version 2023.8.2 that’s causing this.

If I use this config and only reads two registers it works as before 2023.8.2, but if I increase to three registers, I get no value on any of the sensors.

- name: Input_Sensor_Register_1_Plus
  unique_id: input_sensor_register_1_plus
  slave: 1
  address: 0
  slave_count: 1 # count - 1
  input_type: input
  count: 2 # total number of registers to read
  scale: 1
  offset: 0
  precision: 0
  data_type: int16
  scan_interval: 15

- name: Input_Sensor_Register_3_Plus
  unique_id: input_sensor_register_3_plus
  slave: 1
  address: 2
  slave_count: 1 # count - 1
  input_type: input
  count: 2 # total number of registers to read
  scale: 1
  offset: 0
  precision: 0
  data_type: int16
  scan_interval: 15

Any update on this? I have the same issue.

It seems that the problem has been solved in version 2023.8.4 if you remove “count” and “slave” from the configuration.

- name: Holding_Sensor_Register_1_Plus
  unique_id: holding_sensor_register_1_plus
#  slave: 1
  address: 0
  slave_count: 98 # count - 1
  input_type: holding
#  count: 99 # total number of registers to read
  scale: 1
  offset: 0
  precision: 0
  data_type: int16
  scan_interval: 15
