Climate not working anymore : ConversionError description="HVACStatus value not initialized. Can not write new mode."

[hkienlen]

The problem

When changing climate mode, or preset, I got the following error :

Failed to perform the action climate/set_hvac_mode. <ConversionError description="HVACStatus value not initialized. Can not write new mode." device_name="Thermostat.shiatsu Mode"/>

Climate mode is not set.

This happens for every climate device. I'm running KNX climate devices

It was running fine until this spring then I didn't had to use climate anymore. But fall is coming ;)

Hi 👋!
If you use controller_status_address in your knx climate configuration, you will also need to have a readable controller_status_state_address. This DPT now supports both, heat/cool and preset options. In order to send a new value it has to be initialised to not mess with the other value. (Previously it always just assumed "heating").

Please note that it is very unusual to have this DPT as writable address - maybe double check your actuator configuration if it supports DPT 20.102 as writable mode.

From KNX specifications:

DPT_HVACStatus is a non-standard DPT that is used by an HVAC Room controller to report the
currently set HVAC Mode by means of a status/diagnostic Datapoint.

Please also note that there is a bug with decoding controller_status DPT currently. #124257 will fix that.

Hi :)
Thanks for your feedback.
Are you not confusing with operation_mode_address / operation_mode_state_address or controller_mode_address / controller_mode_state_address ?

All my climate devices are configured as follows :

- name: Thermostat.shiatsu
temperature_address:              '8/1/17'
on_off_address:                   '4/0/17'
on_off_state_address:             '4/1/17'
target_temperature_address:       '4/2/17'
target_temperature_state_address: '4/3/17'
controller_status_address:        '4/6/17'
controller_status_state_address:  '4/7/17'
temperature_step:                       0.5
max_temp:                               28
min_temp:                               15
operation_mode_address:         '4/4/17'
operation_mode_state_address:   '4/5/17'

[farmio]

No I'm not.
Is your controller_status_state_address: '4/7/17' readable from bus (read flag)?

In doubt just try to comment out controller_status_address.

[hkienlen]

@farmio , you got it !
Commenting out controller_status_address did it
Thanks 🙏
