Hi @Daniel_Habath ,
If you can send me yor features output I can add fuelcell data.
Best regards,
Pelle
Hi @Gustaf_Berg,
It is greater (not equal). If you set it to 50° it will trigger when it reaches 50,1° (or more).
Best regards,
Pelle
Hi Pelle,
You mean this one?
Hi @Daniel_Habath,
First, make sure you have added your FuelCell device/installation to Homey (even though fuel cell-specific data is not currently available). Then go to the settings for the Viessmann ViCare app (the same place where you entered the Viessmann Client ID) and scroll down to the troubleshooting section.
Next to “Device Selection,” you will find a button labeled Refresh Devices. Click on it, and then select the device you want to retrieve feature data for (the fuel cell device). After that, click Get Feature Data.
A lot of text should appear in the text field. Then click on Copy to Clipboard. Paste the data into an email and send it to me.
Best regards,
Pelle
Hi Pelle,
I have sent you the data by e-mail
best regards
Daniel
Hi again @Pelle_Rosengren,
You wanted feedback on the flow cards. I think it would be useful to have more cards in AND. Hot water temperature would be nice, so we can skip a warming cycle if the temperature is above a certain set point.
What do you think?
Best regards
Gustaf
I will add it in next release ![]()
Dear Pelle,
I am happy to use this app. We have a Vitocal 250 A with 2 circuits. Circuit one for upstairs rooms with 7 Vicare radiator-valves (E3_RadiatorActuator). Circuit two is floor-heating on the ground floor with the Vitotrol 300-E. Hopefully we can also see the valves per room and adjust if wanted.
I will see witch options are available and witch i miss. If you have questions for me in combination with my system just ask.
Greetings Edwin (NL)
@Pelle_Rosengren ; How often does the app sync(renewal frequency) with the Viessmann servers? Kind regards Leon
Check your settings; default = 1x minute = 1.440minutes/day.
1.440 calls per day is the maximum allowed by the Viessmann free API
The update interval is set to every two minutes to be on the safe side.
Br,
Pelle
Hi @Edwin_Sabel !
If you go to the app settings and under the troubleshooting section first refresh devices, select your device and then choose to “Get feature data”. Copy the data into a text file or directly into a mail. When i have the data I can look into implementing support for it. Send the mail to pelle@forint.se.
Br,
Pelle
Hej Pelle i have vi care thermostatic valves, rum sensors and floor heating unit. I hope you can implement it in the app to.
In Sweden we don’t have ViCare+ upp till now and with this more people can control the temperature in the house (and don’t have to call me to change it on my mobile app) , which is not possible with ViCare basic only one person.

Hej Pelle,
We also have vicare Radiator valves in 2 circuits. For example: In one room we have 3 valves and 1 room Sensor. I set the time programs with the vicare app. But maybe there’s a way to set the temperatures of individual rooms for a specific period with homey? That would be a great feature. It would be great to be able to see/set the temperatures of individual rooms in homey dashboards. Perhaps you can implement something like this? Thank you for your support and development of the Viessmann app!
Greetings,
Thomas
Hej Pelle, we have Ellevio electricity effect subscription between 06:00-22:00 and i want to make a flow combination with POTH that will temporary drop the consumption of the heatpump Vitocal 222A , 252A or 222S , with Nibe you can control the rpm of the compressor to keep the max effect per hour in check. Is there something possible with the app ?
Thanks ,Frank.
Hello,
Homey Pro (Early 2023) Version 12.4.1
Viessmann ViCare v1.0.12
Vitotronic 200 Typ KW2
My Viessmann system has two heating circuits. However, I can only control heating circuit 1 (change the operating mode) with the Homey app.
In addition, the “forced Normal” mode is not available in the “Set operating mode to…” tab in Flow, but it can be set via script.
Thank you in advance
Hello Pelle, the viesman app was installed and works fine but to connect with Homey I had problems in the last step when I added the new Vicare device in Homey: when I was asked to log in with my Vicare log in I got the screen with this error: {“error”:“invalid_request”, “error_description”:“Ongeldige omleidings-URI.”}
Hi,
Not sure if everyone got the message from Viessmann that the API Domain changed from:
Endpoints:
Admin and identity control:
2. Identiteits- en toegangsbeheer (IAM):
- Het domein voor onze identiteitsdiensten wordt ook bijgewerkt. Dit moet in uw applicatie worden bijgewerkt om ervoor te zorgen dat de autorisatie correct blijft werken.
- Oud : https://iam.viessmann.com
- Nieuw : https://iam.viessmann-climatesolutions.com
Endpoints should be used and the current domain will be deactivated end of 2025.
On another note:
My device always opens in the “Hot water Normal” window. I would like it to open the “Heating thermostat window instead” as that is really the only window I need to control. Can I force this somehow?
Also, can I add the device as a Thermostat in Homey so I can control it through “Climate”?
