Viessmann Component

Ferdi8819 · May 24, 2022, 11:57am

Hi,

i updated HA today to 2022.5 form i guess 2022.4.

No i lost some entities of my vicare integration.

I don’t get any information about burner modulation or burner starts

Does anybody know what happend?

It has nothing to do with the update. I’m on 2022.5 since release and it worked until 08:32 this morning (CET). Now the most important sensors are unavailable:

binary_sensor.vicare_burner_active
sensor.vicare_burner_hours

Ferdi8819 · May 24, 2022, 3:26pm

I just checked out this python lib:

looks like they fixed something today that meets the problem stated above

mamoel · May 25, 2022, 5:30am

Viessmann changes the API a lot. I’ve never seen an API with so many breaking changes in such a short time.

oischinger · May 25, 2022, 6:54am

It’s also fixed in HA Core now.
The next minor update should resolve the issues

I am gering the same error.
Just from one day to another, without any Updates/changes from my side

This seems to be a server issue recently introduced by Viessmann. Interestingly it doesn’t happen for everyone.

Amgstone · August 15, 2022, 8:53am

good afternoon, tell me how to transfer room_temperature from home assistant to vicare?

wojked · August 16, 2022, 5:31pm

I have two instances of Home Assistant, 2022.8.x

one is running on an Intel machine (no issues with the integration!)
second one is running on RPi (with error the same error)

PyViCare.PyViCareUtils.PyViCareInternalServerError: (PyViCareInternalServerError(…), ‘Request failed with status code 500 and message “Internal server error”

I wonder if the architecture difference is a good debugging direction.

As probably many of us in these days i got a new price from my supplier for gas. So i thought its a good idea to add the price to the energy dashboard to see real time costs.

But unfortunately is the price for gas provided in kwh and in HA its measured in m3.

Whats is the easiest way to add the price now? Is it necessary to recalculate kwh to m3?

verandy · August 22, 2022, 6:28am

verandy · August 22, 2022, 6:29am

Entgegen des Titles ist es recht trivial für die hier nötige Genauigkeit, kWh Preis mal 10 als m3 Preis eingegeben

OZ-70 · August 22, 2022, 3:11pm

Is there anything new to this problem?
I am using HA inside a Docker container on my Synology Diskstation 220+.
Current HA version is 2022.8.5. The problem exists since 7.8.
Maybe this will help to narrow down the problem.
I would be grateful for any help.

oischinger · August 22, 2022, 3:28pm

As a workaround please see https://github.com/home-assistant/core/issues/77050#issuecomment-1221565264

blackfede · August 22, 2022, 4:06pm

Hello to all. I’m quite new to HA and at the moment I’m trying to integrate my Viessman Vitocaldens 222-F with this component. Everything work as a charm, but my device is identified by the PyViCare library as “HeatPump”. The device identifier is “CU401B_S” however this is not an Heat Pump but an Hybrid generator used for both Heating and Hot Water.

I made some test using PyViCare library on a python CLI and I’m able to access all the relevant data (compressor, burner and various temperature). I will open an issue to PyViCare to have my model correctly assigned. However i wonder how I can force the device type inside the Viessman Component in HA.

Here an extract of “download diagnostic”, as you can see the heating type is “auto”.

      "entry_id": "e5285b6427d56d1d59a640f75a3eadf8",

Hey @blackfede ,

When setting up the Integration you can choose the heating type. Default is auto.

blackfede · August 22, 2022, 6:56pm

Thanks! I didn’t think about that possibility.

Federico

blackfede · August 22, 2022, 8:40pm

Hi everybody, digging around i found this site Announcements | Viessmann. It seems that Viessman is announcing here their changing in the API. Hope this can help… even if I understand that the most interested are the guys that are developing PyViCare.
