Cannot access hot water temperature

[philipp-kuttner]

The problem

I‘m unable to get the value of the water temperature.
The entity water_heater.vicare_water delivers the state AND the value, but I cannot access only the value.

What version of Home Assistant Core has the issue?

core-2022.11.5

This should be fixed with #84720
can you please check with 2023.01 (yet to be released as stable)

Hi @oischinger.
I updated today to 2023.2.2, but I cannot access to this data.
Do you have any other tips for a solution?

P.S.
I used this entity:
water_heater.vicare_water
But this entity only returns for example "on", not the water temperature.

[rolandsteinmeyer]

I have this in water_heater.vicare_water_0 attributes:

min_temp: 10
max_temp: 60
current_temperature: 48.3
temperature: null
target_temp_high: null
target_temp_low: null
friendly_name: ViCare Water 0
supported_features: 1

current_temperature is ok. target temperature should be in attribute "temperature" but is "null". I can sucessfully set new target temperature with service "water_heater.set_temperature". It just doesn't show in "temperature".
I am not sure, but I think this has worked a few days before. Viessmann may have changed something in the API, there was a service downtimes some days ago.

@philipp-kuttner
You would need to create a template sensor to have a dedicated attribute for the water temp. See https://www.home-assistant.io/integrations/template/

Concerning what @rolandsteinmeyer mentioned: There's currently an issue on PyVicare which was used to report a breaking change: openviess/PyViCare#285
But so far I wasn't aware that the water temperature attribute is affected by this.

@rolandsteinmeyer you can upload the diagnostic data then we can check

[rolandsteinmeyer]

temperature is back today in water_heater. I had some 'EXPIRED TOKEN' errors in the log, it might have sorted itsself out in subsequent requests. Log attached.

PyViCare.PyViCareUtils.PyViCareInternalServerError: (PyViCareInternalServerError(...), 'Request failed with status code 502 and message "INTERNAL_SERVER_ERROR".

Am still not able to turn on DHW on the E3 platform

Hi, is this issue still pending?
I´m trying to use the water temperature as a separate sensor, but my template sensors returns the numeric value with question marks.
code:

• name: 'Brauchwassertemperatur'
  unit_of_measurement: '°C'
  device_class: temperature
  state: “{{ state_attr('water_heater.vicare_water', 'current_temperature') }}”

Result: “51.6”
This non-numeric value cannot be used as statistical data.
Tested the same with the climate.vicare_heating and current temperature: The temperature is also returned as string value with question tags.

@garagenlager Thanks for your code. This helps me a lot. And I fix the problem with the string value.
state: "{{ state_attr('water_heater.vicare_water_1', 'current_temperature') | replace('“', '') | float }}"

[garagenlager]

@ja-m Thanks for your help. Nevertheless, I´m still getting the string value back as result with question tags. The replace order is not executed for some strange reason. It seems that the question tags around the expression "{{....}} cause the problem. If I delete these, the yaml file is not acceted due to syntax error.

[garagenlager]

Hi, just to present the working solution now:

• name: "Brauchwassertemperatur"
  unique_id: "Brauchwassertemperatur"
  unit_of_measurement: °C
  device_class: temperature
  state_class: measurement
  state: "{{ state_attr('water_heater.vicare_water', 'current_temperature') }}"

It seems that the sate class measurement was missing.
