App is totally unusable. Installed it, registered an account, then tried to create a home - but when I entered the serial number for my boiler, I got a network error message. Tried for the next two days, same thing. Cleared local storage, deleted app, reinstalled app - exactly the same thing. I can't add my boiler to manage it in the app, which is the point of the app! Very disappointed and not a great first impression of Vaillant

Hi Neill, I'm sorry to hear you are having an issue. The app requires the serial number of the Vaillant internet gateway. If you need more support with this, please contact us on 0344 736 0049.

The app is asking for the qr code or serial number of the gateway. I've scanned the barcode at the back of the gateway but it doesnt respond. I've tried inputting all the number on the back of the gateway, and all the numbers on the heating controller but it wont let me get any further. I cant even use the original app any more. Very disappointing.

Just terrible. Have lost pretty much all control over my heating system after being forced to change to this app. Previous VRC700 app wasn't amazing but at least everything worked. Customer service useless, no suggestions beyond restarting or reinstalling, now telling me to "bear with us as we iron out the small issues we are experiencing." Now have rooms in my house that are too cold to be in (including a child's bedroom) and no solution on the horizon. Really wish I hadn't chosen Vaillant.
