Home Assistant / API doesn't get data from Viessmann hybrid system

[Mnovu]

The problem

Hello,

I have connected Home Assistant and my Viessmann hybrid system (Vitocal (heating pump) and Vitodens (gas)) via Viessmann API.

In HomeAssistant, however, only Vitodens is recognized, even if I enter "hybrid" or "heatpump". But I need both devices or if only one works, I would need the heat pump.

Overall goal: I as house owner want to use my pv energy to heat up the water in the puffer/water tank.

What am I doing wrong? Or does the API not pass the data?
Thanks for feedback 🙂

P.S. I created a ticket at the Viessmann dev portal too (german only) https://www.viessmann-community.com/t5/Feedback-API/Home-Assistant-API-erkennt-Hybrid-System-bzw-Waermepumpe-nicht/m-p/376282#M241

The integration currently supports only one device (the first one).

https://github.com/home-assistant/core/blob/b323295aa15ff6ac81e46b213a2f22440f0460de/homeassistant/components/vicare/init.py#L85-L87

I have prepared a PR to enable all devices that are reachable by the used PyViCare library. I run this myself with two * Vitodens* via two VitoConnects.

I would be really interested if this also works for your!

[Mnovu]

hey @CFenner thanks for that! Could have looked into the code as well, just didn't think about it :(

Since I am pretty fresh to the show (just started yesterday with HA): How can I test this? Is there an option to enable PRs on the running integration (e.g. enable test versions?). Or any other way?

[CFenner]

So you can simply download PR code and copy the folder vicare from homeassistant/components to config/custom_components/ on your instance.

@joostlek you mentions some script to try out PRs, can you share that?

[joostlek]

cd /config
curl -o- -L https://gist.githubusercontent.com/bdraco/43f8043cb04b9838383fd71353e99b18/raw/core_integration_pr | bash /dev/stdin -d vicare -p 96044

After -d comes the domain and after -p comes the pull request id

[Mnovu]

@CFenner ok, thanks. Will try that and share feedback. This week is quite busy.

Moved testing results over to https://github.com/home-assistant/core/pull/96044#issuecomment-1785759049

[CFenner]

In the api description heat pumps are listed under the paid api plan. Are you aware of this?

[Mnovu]

No, see picture. But it’s hidden :D

@CFenner - thanks a lot for your contribution, i just implemented it in my HA setup as i will extend my current heating system (gaz boiler) with a heatpump in 2 weeks. I also recommend to decrease the nb of api calls by implementing 2 automation (1 at night with 30min delay, and one for daytime with 2 or 3 min interval). i can share the script i use ;-). dont forget to disable the poll feature in the vicare integration

[niouniou49]

@CFenner when HA will have new releases update, will your changes stay or do i need to manually implement them again?

[CFenner]

If you copied the PR content to your custom components folder, it will stay.

[niouniou49]

you mean the vicare folder should be in custom components folder?

[CFenner]

Yes, simply use this script. It will do the rest for you.

[niouniou49]

i just run your command 'cd /config curl -o- -L https://gist.githubusercontent.com/bdraco/43f8043cb04b9838383fd71353e99b18/raw/core_integration_pr | bash /dev/stdin -d vicare -p 96044 without changing anything

[niouniou49]

ok so all good, i guess ;-)

[l2jalbe]

everything is working for me too. I have a lot of viessman device (heat pump, gas heater, inverter and photovoltaic and water solar heater). With 2024.1 update and this PRoject now i can use the supported devices

@CFenner if you need some report/log ask me

[TimHeu]

Hello,

I am an absolute beginner. I would also like to read out several devices. What do I need to download and how can I insert it step by step, and of course where? Maybe someone has the desire and time to explain this to me?

Thank you!
