VALIDATION_ERROR

[RafalHo]

Hello,

from the very beginning I have a problem with this integration, the HA displays the temperature of domestic water and heating, but I can not change anything, nor, for example, turn off the heating. I can only set the temperature of domestic water. I tried the version with energy support, but there was no new entity for gas or electricity consumption, and I have all this data in the Vicare application.

Below I am pasting the log that was generated when I tried to turn off the heating.

Looks like an auth failure. Are you sure you retrieved the correct client id and use correct username and password?

[RafalHo]

I checked again, but the data is correct.
If they were wrong, would I see the current heating and domestic water temperature in HA?
I can even change the domestic hot water temperature, but I cannot turn off the heating or change to a schedule.

[oischinger]

Maybe it's a read only token or so.
Did you follow the instructions here to create the token: https://github.com/somm15/PyViCare#api-usage-in-postman

[RafalHo]

I did according to this: https://www.home-assistant.io/integrations/vicare/#configuration

[oischinger]

Yes, that's the same.
Maybe it's also the stored token. The integration persists a token in /config (vicare.token I believe) can you tryto delete it?

[RafalHo]

Found the token and removed it (found here: config.storage\vicare_token.save)
I even generated a new Client ID on developer.viessmann.com/en/clients.
Unfortunately, still an error, the log is attached below.
Should I use some other integration instead of the original one (https://www.home-assistant.io/integrations/vicare/)?
Is it possible to read gas and electricity consumption at all through integration?

[Pampasgras]

I have the very same issue when choosing the Auto option in Pyvicare Heating
(I can set the temperature, and read other statistics)

--> I use climate.set_vicare_mode instead
So I cannot use the lovelace thermostat

[oischinger]

Can you please check which vicare_modes your device supports? you should see it as an attribute of the climate entity

[Pampasgras]

Can you please check which vicare_modes your device supports? you should see it as an attribute of the climate entity

hvac_modes:

• heat
• 'off'
• auto

vicare_modes:

• standby
• forcedReduced
• forcedNormal
• heating

Vicare modes are all supported with climate.set_vicare_mode. (tested them all)

climate.set_hvac_mode "heat" --> vicare_mode forcedNormal
climate.set_hvac_mode "off" --> vicare_mode forcedReduced
climate.set_hvac_mode "auto" -->error 422 (I expect vicare_mode heating)

[oischinger]

I have created a branch with a potential fix @KurtSponik : #85

To the others: Can you please provide the same information as @KurtSponik did?
Do all your heating devices have in common that they don't provide domestic hot water?

[ol3k]

I get the same Validation Error (but with dhw mode)

hvac_modes:

• heat
• 'off'
• auto
  min_temp: 3
  max_temp: 37
  preset_modes:
• comfort
• eco
  current_temperature: 28
  temperature: 22
  hvac_action: idle
  preset_mode: null
  room_temperature: null
  active_vicare_program: normal
  active_vicare_mode: dhwAndHeating
  heating_curve_slope: 0.3
  heating_curve_shift: 0
  vicare_modes:

[oischinger]

@ol3k
I'm interested in the data shown in the developer tools like below:

[ol3k]

I think this is the data I copied above (just c&p with mobile phone out of HA, find screenshot attached)

[darianf01]

Same issue as encountered by @ol3k when trying to change the hvac mode

PyViCare.PyViCareUtils.PyViCareCommandError: (PyViCareCommandError(...), 'Command failed with status code 422. Reason given was: VALIDATION_ERROR')
Vitodens 100-w + Vitoconnect OT2 + Vitotrol OT1

[TOMSLAUS]

Same issue to me, error gets thrown when trying to do anything.
