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.

I changed my phone and, on the new one, once I log in, I'm required to go through the initial steps once again (confirm the address,scan the qr code). The only problem is that when I scan the code I get the error that the device is already registered but I have no possibility to access it. The message also states to contact the support team... where to contact it, no idea, on the site there is no contact details. It seems to be a "one tine only" kind of app.

I tried creating a new account twice now, using two separate email addresses. I never received the activation email and I am unable to use the app. There is no option to resend activation email or contact support. Very frustrating! 24 hr update: support team responded to my review comment. I received the activation email after following the steps indicated and I managed to add the device in the app. So far so good, seems user friendly enough.
