Hey,
The current temperature of the hot water should be available right now already. It is shown on the theromostat where you change the target temperature for the hot water normally.
For the circulation pump, I will investigate, recorded it on my GitLab issue tracker:
Hey Jan,
Iāll try to work out something to help people in the translation efforts! Stay tuned!
Normally I have created issue tickets for everything you guys reported here and is not resolved yet:
If I missed some, please feel free to report then Iāll add them to prevent that I forget about them.
This afternoon I plan to rework the authentication logic, so that it gets easier to use the application and potentially fix the fetch problems some users reported.
Guys,
Iāve made a major upgrade to the application, this upgrade will however be slightly breaking. Iām sorry for this.
v0.4.1 is now available for testing.
Two major changes occured:
For the migration purposes, you can try to repair the device to get the OAuth2 properly linked. Iāve been unable to try it, since I did not had the old device anymore. If it fails, you might need to re-add the device, Iām terribly sorry for this inconvenience.
In the settings now you only need to enter your Client ID. All other settings are gone, except the retrieval of features.json and installations.json.
Hi Kenny,
Advies is tot update the manual, the callback url in the dev portal nee to be changed to https://callback.athom.com/oauth2/callback.
I have a Vitocal 200-s. But I cannot add vitocal device, I can add vitodens with out direct error. But when I want change the temp I get a error (the expression evaluted to a falsy value.) and I cannot see detail info of the hot water temp. I can also add vitocal with vitotronic 200 but directly with a error/warning about the thermostat_mode.
So the changes to the login methode are good and now working for me.
Bellow Some schreenshots.
Hey,
That good to hear! I did not had time to update the docs yet, the UI should Refer to a getting started which should use the correct info.
I will update other docs also during the next days.
The issue with the thermostat mode was one that I expected. Another user reported the same. It serms some vitocal devices, despite beding the Same model, have different programsā¦
Thats why I added the generic vitocal in hope to fix it. It did not find Your device I understand? I will dig into that because it should find it.

So I can add two types. Where one type gives an error message immediately. The other seems to work at first sight but can not change temperature for example. But the information of the hot water circuit is missing.
I will send my installation.json and feature.json. Maybe this helps you to find the issue. But I am already very happy with the progress, very happy with it.
Thx, further patches and change will be for monday or tuesday.
Hi, since version 0.4 I get Oauth errors.
When I fill in my client-ID again, the app doesnĀ“t confirm with āSavedā.
Reinstalled the app, but no change.
If I try to install my Vitodens 200 E3, the app opens an error message on iam.viessmann.com saying {āerrorā:āinvalid_requestā, āerror_descriptionā:āInvalid redirection URI.ā}
This is still http://localhost:4200/ at Viessmann
Am I getting something wrong or shall I just wait for next week / next version?
Have a nice weekend and thank you again for the work and time! I will be fantastich to have the heating on Homey.
You need to chance the URI to
https://callback.athom.com/oauth2/callback
Iāve just created a new API just to be sure
Thank you, that works!
DidnĀ“t recognise the post above, sorry.
The generic āVitodensā is not working for me, but installation with āVitodens 200/300 with Vitotronic 200ā was working and looks like as before (with 2 circuits).
In Insights are the empty entries now removed.
Thanks for your efforts! Iām currious to the next versions.
Guys,
A quick fix this morning: v0.4.2.
This version should solve the problems with the generic devices I think. It was getting late yesterday and it seems I mixed up the Vitocal/Vitodens devices somehow 
.
Iāve added some more failsafe checks for the values, which should avoid the falsey value too.
PS, now I am going to enjoy my Sunday, no further updates today, Iām sorry.
Kind regards,
Can you guys add multiple clients in the Viessmann portal? I donāt see any add button and I suspect this is a Viessmann bug.
And fyi: I had to remove my old device and add a new one for the breaking changes in 0.4.1 to work again. Repair didnāt work. But no problem, these things happen off course in early dev
Hey,
Each package on the Viesmann website has only 1 active API client.
The only difference with a subscription is the calls per day.
When you edit your existing client, there is a button to add URI.
Perhaps you can add the URI for your additional client here.
However, you will quickly reach the max number of calls per day.
After which your api will no longer communicate.
Hi Kenny,
for me it was now possible to install the generic device āVitadentā, and itās working. It shows also the two circuits.
I was wondering that a window opened during installation, and asked for user name and passowrd of my Viessmann account. This is different to the installations before, but I think this has changed in the new version and is expected behaviour.
So, enjoy now the Sunday. 
But donāt forget to come back with new ideas!
Thatās idd expected behaviour of the new authentication method.
v0.5.0 available for test, if this one is giving good results, Iāll submit this version for certification again.
Changes:
Is it possible to add power consumption for Vitocal devices also please?
Hey @Blooddrunk ,
The features.json which I received from all Vitocal users donāt include the necessary fields which expose the power consumption. For all Vitodens devices I have fields like heating.power.consumption.total, but they (and something similar) donāt appear to be in the features.json files of the Vitocal devices.
Either Viessmann does not provide them, either I look over it, or it is only part of the paid plans.
Kind regards,
