Modbus climate integration problem

[francescoguidetti]

The problem

This is th configuration of my climate device:

• name: "AC 1" address: 1005 target_temp_register: 1004 temp_step: 1 hvac_mode_register: address: 1001 values: state_auto: 0 state_cool: 4 state_heat: 1 state_fan_only: 3 state_dry: 2 write_registers: true hvac_onoff_register: 1000 write_registers: true

When I call the service climate.turn_on, the integration write with function code 16 the value 1 in register 1000 (hvac_onoff) and the value 1 in register 1001 (hvac_mode) and this is incorrect if I want turn on the device in cold mode and my device stop working correctly Climate.turn on should write only in register 1000 (hvac_onoff) There is another service (climate.set_hvac_mode) to set the mode

This log have nothing to do with the modbus integration. If you think there are a problem in the integration, you need to supply a debug log for the integration as pr documentation of the modbus integration.

[francescoguidetti]

I added these lines in configuration.yaml

logger: logs: homeassistant.components.modbus: debug pymodbus: debug

but nothing interesting in log:

home-assistant_2023-06-22T11-20-42.196Z.log

what i'm missing ?

[janiversen]

you did not restart HA.

[francescoguidetti]

I have already restarted HA but I did it again , and checked again the configuration
but nothing in log

home-assistant_2023-06-22T15-11-54.110Z.log

[janiversen]

then the debug is not added as pr documentation. Once active you will see hex dumps of what is being sent and received.

Restarting the integration is not enough, so please be sure you restarted the whole HA.

[francescoguidetti]

In attachment part of my configuration.yaml I restarted Home assistant and the whole system but I cannot see hex dump. Are you shure that the log of modbus integration in core 2023.6.3 is working correctly? I checked again and again but I cannot find anything wrong in my setup Thanks for your patience and support

configuration.yaml.txt

[janiversen]

It works on my system.
