MODBUS Climate lacks option to set HVAC_Modes

[stefanschaedeli]

The problem

I try to manage my Boiler temperature and operation mode with the Climate module, which works great for the temp setting. Unfortunately, I can define the register for and the options of operating modes (the config is not accepted, nor ca I change in the GUI etc.

core-2022.10.5

Example YAML snippet

- name: "HovalConnect"
  type: tcp
  host: 10.11.11.8
  port: 502

#Climate  
  climates:
    - name: "Hoval Boiler"
      address: 1500
      input_type: holding
      count: 1
      max_temp: 60
      min_temp: 45
      offset: 0
      precision: 1
      scale: 0.1
      target_temp_register: 1497
      temp_step: 1
      temperature_unit: C
      hvac_modes: "standby,Woche 1, Konstant"

Anything in the logs that might be useful for us?

No response

Additional information

It would be enough for me that I can set the modes and chose it from there and use another automation to do the actuall change of the operation mode. I'm just hoping I can get rid of my other "drop down" selector of the operation mode

The problem is that there are no standard way of settings the hvac mode. If you know how to do it on your system define an extra register and use that.

Thanks for the feedback, I have the register for that already, but how can I use it in the climate config?

[janiversen]

you cannot it is separate. But you can add automation that combines the two.

[stefanschaedeli]

Sorry, now I got confused :D How would I combine with automation, I have only one setting which is auto:

`
if CONF_HVAC_MODE_REGISTER in config:
mode_config = config[CONF_HVAC_MODE_REGISTER]
self._hvac_mode_register = mode_config[CONF_ADDRESS]
self._attr_hvac_modes = cast(list[HVACMode], [])
self._attr_hvac_mode = None
self._hvac_mode_mapping: list[tuple[int, HVACMode]] = []
mode_value_config = mode_config[CONF_HVAC_MODE_VALUES]
for hvac_mode in HVACMode:
if hvac_mode.value in mode_value_config:
self._hvac_mode_mapping.append(
(mode_value_config[hvac_mode.value], hvac_mode)
)
self._attr_hvac_modes.append(hvac_mode)
else:
# No HVAC modes defined
self._hvac_mode_register = None
self._attr_hvac_mode = HVACMode.AUTO
self._attr_hvac_modes = [HVACMode.AUTO]

`

The code is indicating that I could pass a information about the modes, but it fails back to only having auto.

[janiversen]

The modbus integration does not support setting of HVAC_MODE ! so if you want it integrated you need to write some automation and combine the extra register with the modbus climate.

[stefanschaedeli]

okey, understood. do you have any example or direction on how the "combin the extra register with modbus climate" ?

[janiversen]

no, I have next to none experience with automation scripts, I am a developer.

amazing :D thanks for confirmation :) Do you have any idea in which production release this could be in?

[avishorp]

It has been merged to the "next" branch, so I suppose it's going to be in the next version, but I'm not sure. ‫בתאריך יום ב׳, 31 באוק׳ 2022 ב-8:20 מאת ‪stefanschaedeli‬‏ <‪ ***@***.***‬‏>:‬

Okey, thanks anyhow :) looking forward for this, thank you for your efforts :) Do you have a "BuyMeACoffee" or something?

[stefanschaedeli]

wop wop, its in the November release ! :)

Tried it out but get an issue unfortuntely ->

climates: - name: "Hoval Boiler" address: 1500 input_type: holding count: 1 max_temp: 60 min_temp: 45 offset: 0 precision: 1 scale: 0.1 target_temp_register: 1497 temp_step: 0.2 temperature_unit: C hvac_mode_register: address: 1496 values: auto: 1 off: 0 heat: 4

Invalid config for [modbus]: [False] is an invalid option for [modbus]. Check: modbus->modbus->0->climates->0->hvac_mode_register->values->False. (See /config/configuration.yaml, line 61).
