You can check the signal strength as follows: In the ViCare app under “Settings”, navigate to “Communication module” and then to “Signal strength”.
If the signal is weak or very weak, you can improve it as follows:
- Ensure that there is a stable internet connection from your internet provider.
- If you have recently changed your internet provider and/or router, re-establish the connection.
- If you have an older generation Viessmann heating appliance with the Vitoconnect communication module, try to position it in a location with a stronger signal.
- Use Wi-Fi repeaters to improve the connection between the Vitoconnect and your router.
- If the signal strength is still very low, restart your communication module. To do this, navigate under “Settings” to “Communication module” and click on “Reboot communication module”.
You can also check in the app under “Notifications” whether Viessmann is currently carrying out maintenance work or whether the system is being restored after a temporary outage.
