I have spoke with customer service and went through all of their steps on the phone and no one could get it to connect to the app even though the wifi finds the boiler. Now 8 months later after various app updates, nothing is fixed and it still won't establish connection with the app. Always finds the boiler via wifi but the ViCare app will just say searching for device or whatever. This is probably the worst app I have dealt with with even cheap products having no problem pairing to an app.

Impossible to get support. The app worked fine for a few years, but for the last couple of months, despite the boiler being connected to the WiFi, the app comes up with an error message "Your system is not connected to the internet." I can see that there is data traffic from the boiler to the internet, but the app refuses to find it...

since the latest updates, this has broken the programs. Often, when the boiler should be going into reduced mode, the boiler is showing as in reduced mode but the temperature is no longer being turned down, so you end up in a weird position where the boiler think it is in reduced mode but still actually on, and on at the normal mode temperature.
