To connect your Viessmann heating system to the ViCare app, follow these steps:
For registration, create a user account in the app under "Create new account". To create an account, you need to provide the following information:
The ViCare app can be downloaded from the App Store or Google Play Store. Observe the minimum requirements for your operating system.
ViCare is a native app, i.e., developed for mobile operating systems. A PC version is currently unavailable.
The Vitoconnect module can be easily registered using plug & play functionality. All you need to do is scan the included QR code with your smartphone. Make sure that the Vitoconnect module and the Vitotronic control unit of the heating system are connected to power and the internet using the cable included in the delivery. Scanning the code allows you to connect Vitoconnect to your account in the ViCare app. To do this, you need to download the app and create a user account in it.
Simply download the ViCare app to your new device. Then log in using your email address and password. You don't need to create a new account or reconfigure the app. After logging in, you can continue using the ViCare app services.
For security reasons, Vitoconnect is permanently connected to the control unit of the corresponding heating system. Before purchasing a new Viessmann heating system, you need to reset Vitoconnect. To do this, send an email to: td@viessmann.com. This should be done from the address you used to register your Vitoconnect. Then install Vitoconnect and connect it to the new heating system.
The QR code is also attached to the Vitoconnect housing, directly on the circuit board. Disconnect the power and USB cables from Vitoconnect and remove the housing cover. The best way to do this is to pull the housing toward you from below and then lift it. For detailed information, see step 1 in the PDF file "Commissioning".
Basically, the operating system, i.e., the ViCare app, notifies when and what updates are available. You should confirm this notification, then download and install the updates. With the appropriate setting on the smartphone, updates can be downloaded automatically.
All available extensions will be installed along with app updates. Therefore, you should always keep the app up to date. After each update, the notification will indicate what's new and what has changed.
Available for iOS and Android.

If the ViCare app does not connect to the heating system, please check whether an Internet connection is available.
Completely close the app. If you are using an Apple device, double-press the Home button and swipe up to close the app. Then restart the app. The ViCare app should now work again.

Currently, the ViCare app does not support displaying the flow temperature.
To view the boiler water temperature, go to the Settings menu, scroll down to Devices, and select Boiler. The boiler water temperature is displayed for all oil and gas heating systems.

Check the position of your router and inspect all connecting cables.
If both are fine, install a Wi-Fi repeater to boost the signal. This should ensure a stable connection between your smartphone and the heating system.
The actual temperature is displayed only if the app receives this data from the heating system. The heating control unit must support this function. If you have not installed a room thermostat, for example on the remote control, no data is available, and the app will display “--”.
