Still absolutely sh't and an utter waste of time. Didn't work, years down the line and it still doesn't work. This app is a joke. Between this app and phoning technical JUST TO COMMISSION will waste a whole day. To any other gas engineers out there, it's not worth it.

Works great! I Initially had an issue connecting with the QR code, but then I switched to manual connect by entering the password generated by the boiler control and it was smooth sailing. Much easier to program the boiler with this app than via HMI - especially if the unit is in a tight space. Bravo Viessmann! Best app ever for programming boilers.

Great app, when it works. I barely get to monitor the systems I've installed, all I get is a 403 page when I try to view them. Update - the installs were back for a while, but now I'm back to the 403 page when I go to the monitoring section. Very frustrating since I have a client with issues and I can't see the system.
